Cell Culture Plates

<h2 class="p2"> What are Cell Culture Plates?</h2>
 Cell culture plates are sterile, single-use polystyrene multi-well vessels used to grow, treat, and analyze cells in parallel across multiple conditions in a single vessel. All formats are E-beam sterilized to SAL 10⁻⁶, certified DNase/RNase-free and non-pyrogenic, and individually wrapped in peelable film. Choose TC-treated flat-bottom plates for adherent mammalian cell culture, assays, and transfection; choose non-treated plates for suspension, hematopoietic, and hybridoma cells; choose glass-bottom plates for live-cell confocal and high-resolution fluorescence imaging.

<h2 class="p2">How to Choose Cell Culture Plates</h2>
 Well Count by Application Scale 6-well plates (9.4 cm&sup2;/well) are the standard for transfection, siRNA knockdown, Western blot sample preparation, luciferase reporter assays, and colony counting &mdash; any protocol that requires &ge;5 &times; 10⁶ cells per condition. 12-well plates (3.8 cm&sup2;/well) support medium-scale culture for ELISA lysate preparation, flow cytometry staining, and viral infection studies. 24-well plates (1.9 cm&sup2;/well) are versatile for drug dose-response at medium throughput, primary cell culture, and viral plaque assays. 48-well plates (0.95 cm&sup2;/well) bridge 24-well and 96-well scale for intermediate throughput experiments. 96-well plates (0.32 cm&sup2;/well) are the workhorse for high-throughput cell viability (MTS, MTT, CCK-8), cytotoxicity, ELISA, reporter gene, and compound screening assays. 384-well plates are used for ultra-high-throughput screening (HTS), where reagent cost per well drives miniaturization. TC-Treated vs. Non-Treated vs. Glass Bottom TC-treated (vacuum plasma&ndash;treated, contact angle &lt;10&deg;) flat-bottom plates support adherent mammalian cell monolayer formation &mdash; required for HeLa, HEK293 (adherent), CHO-K1, Vero, A549, MCF-7, and primary cells. Non-treated plates maintain a hydrophobic surface that prevents attachment &mdash; used for suspension cell lines (Jurkat, K562, HL-60), hybridoma culture, and spheroid/organoid formation in U-bottom wells. Glass-bottom plates combine a polystyrene plate body with a borosilicate coverglass floor (0.16&ndash;0.19 mm thickness), matching the No. 1.5 coverglass standard required for confocal, TIRF, and super-resolution microscopy. Flat vs. Round (U) vs. V-Bottom Well Geometry Flat-bottom wells provide a flat imaging surface for phase-contrast and fluorescence microscopy, uniform cell monolayer coverage, and reliable OD measurements in plate readers. Round (U)-bottom wells concentrate cells and particles to the well centre by gravity &mdash; used for rosette assays, hemagglutination inhibition (HAI), and hanging-drop spheroid culture. V-bottom wells have a sharp vertex that pellets cells tightly for wash steps in flow cytometry and immunophenotyping panels. Plate Lid and Evaporation Management NEST Scientific cell culture plates ship with a clear polystyrene lid. For high-throughput assays running 72&ndash;96 hours, edge-well evaporation in 96-well and 384-well formats can introduce artefacts; NEST Low Evaporation EDGE plates have an inter-wall design that reduces edge-well evaporation by maintaining humidity in the peripheral wells during long incubations.

<h2 class="p2">What are TC-Treated Cell Culture Plates?</h2>
 TC-treated (tissue culture&ndash;treated) cell culture plates are sterile, single-use multi-well polystyrene plates whose well surfaces have been modified by vacuum plasma treatment to introduce negatively charged oxygen-containing groups (carboxyl, carbonyl, hydroxyl), reducing the water contact angle from ~75&ndash;90&deg; (untreated PS) to below 10&deg; (hydrophilic). This surface modification directly enables attachment, spreading, and monolayer formation of adherent mammalian cell lines. TC-treated plates are the default format for all adherent mammalian cultures, cell-based assays, ELISA preparation, compound cytotoxicity screening, transfection, and gene expression studies.&nbsp; 
<h2 class="p1">What you will find:</h2>
&nbsp;
&bull; 6, 12, 24, 48, and 96 well formats for different workflows &bull; Tissue-culture-treated surfaces for reliable cell attachment &bull; Clear plates for easy monitoring under the microscope &bull; Uniform wells for consistent seeding and growth &bull; Sterile options to maintain clean conditions &bull; Lids designed to reduce contamination and evaporation
&nbsp;
<h2 class="p2">How to Choose TC-Treated Cell Culture Plates</h2>
 Well Format by Cell Number and Assay Type 6-well TC-treated plates (9.4 cm&sup2;/well) are the standard for Western blot preparation, siRNA transfection, viral infection, protein overexpression, and colony-forming unit (CFU) assays requiring &ge;3 &times; 10⁶ cells per condition. 12-well plates (3.8 cm&sup2;/well) suit medium-scale reporter assays, luciferase quantification, and ELISA from cell lysate. 24-well plates (1.9 cm&sup2;/well) are versatile for cytotoxicity dose-response in 4&ndash;6 conditions per plate, primary cell experiments, and viral plaque assays. 96-well flat-bottom TC-treated plates (0.32 cm&sup2;/well) are the universal format for cell viability (MTS, MTT, CCK-8), compound screening, ELISA, reporter gene assays, and qPCR lysate preparation across 8&ndash;12 concentrations with triplicate wells. 384-well plates reduce reagent cost per compound for HTS drug discovery programs. Lot-to-Lot TC Treatment Consistency For longitudinal drug screening, biomarker validation, or multi-site studies, lot-to-lot variation in TC treatment can alter cell attachment density, proliferation rate, and assay Z-factor. NEST Scientific verifies vacuum plasma treatment by water contact angle goniometry on each manufacturing lot; the release criterion is contact angle &lt;10&deg;. Request lot certificates when adopting TC-treated plates for GLP- or GMP-regulated assay workflows. Low-Evaporation EDGE Plates For 96-well dose-response assays running 72&ndash;96 hours, peripheral (edge) well evaporation can increase medium osmolality in the outer ring by 10&ndash;20% versus inner wells, introducing a systematic bias in IC50 determinations. NEST Low Evaporation EDGE 96-well TC-treated plates use an internal well ridge design that reduces edge-well evaporation during extended incubations. Use EDGE plates for any dose-response study where incubation time exceeds 48 hours. Cell Line Compatibility TC-treated NEST plates support attachment and monolayer culture of: HeLa (cervical), HEK293 (adherent), A549 (lung), MCF-7 (breast), U2OS (bone), CHO-K1 (ovary, adherent), Vero (kidney), MDCK (canine kidney), NIH 3T3 (mouse fibroblast), MRC-5, 2BS, 293T, L-929, and standard primary cultures including dermal fibroblasts, endothelial cells, and epithelial cells. Do NOT use TC-treated plates for Jurkat, K562, HL-60, suspension CHO-S, hybridomas, Sf9, Hi5, or any non-adherent cell line. Plate Reader and Automation Compatibility NEST Scientific TC-treated 96-well flat plates are compatible with all common microplate readers (BioTek Synergy H1, Molecular Devices SpectraMax i3x, PerkinElmer EnVision, BMG Labtech CLARIOstar) for absorbance, fluorescence intensity, and luminescence detection. Plates conform to ANSI/SLAS 1-2004 through 4-2004 SBS dimensions for automated liquid handlers (Tecan Fluent, Hamilton STAR, Beckman Coulter Biomek i7).

Storage Boxes & Racks

<h2 data-section-id="1hv97bw" data-start="0" data-end="47">What Are Laboratory Storage Boxes and Racks?</h2>
&nbsp;
Laboratory storage boxes and racks are essential organizational systems used to store, organize, and protect cryogenic vials, microcentrifuge tubes, centrifuge tubes, and microscope slides across freezers, cold rooms, and benchtop environments. Storage boxes are typically lidded, grid-based containers used for long-term sample organization in ultra-low temperature conditions, while racks are open-frame supports used for active handling during laboratory workflows such as pipetting, vortexing, and reaction setup.
Cryogenic storage boxes are commonly designed to hold 81 vials (9&times;9 format) or 100 vials (10&times;10 format), and are compatible with storage conditions ranging from &ndash;196 &deg;C in liquid nitrogen vapor phase to +121 &deg;C for autoclave sterilization (depending on material). Tube racks, on the other hand, provide stable upright positioning of tubes during active benchwork and are not primarily intended for long-term freezer storage.

<h2 data-section-id="flyrii" data-start="1159" data-end="1199">How to Choose Storage Boxes and Racks</h2>
&nbsp;
Vial Format and Capacity
The first selection criterion is compatibility with tube size and grid layout. The most common format is the 81-place (9&times;9) box designed for 1.0&ndash;2.0 mL cryovials. Smaller or specialized formats may accommodate 5 mL tubes or different vial diameters depending on grid spacing. Proper matching ensures secure fit, easy retrieval, and consistent sample organization in high-density storage systems.
Temperature Range
Material selection determines allowable storage conditions. Polycarbonate cryogenic boxes are the most versatile, supporting temperatures from liquid nitrogen levels (&ndash;196 &deg;C) through &ndash;80 &deg;C freezer storage and up to autoclave sterilization at +121 &deg;C. Cardboard freezer boxes with moisture-resistant coating are designed for economical freezer storage and can withstand ultra-low temperatures, but they are not suitable for autoclaving or long-term moisture exposure.
Tube Rack Materials and Use
Polypropylene racks are widely used because they are autoclavable and chemically resistant, making them suitable for sterile workflows. ABS and polystyrene racks provide lower-cost alternatives for general laboratory bench use but are not designed for autoclave conditions. For freezer organization, stainless steel racks are often used to hold multiple cryoboxes within &ndash;80 &deg;C upright freezer systems, improving accessibility and spatial organization.
Slide Storage Boxes
Microscope slide storage boxes are designed to protect standard 25 &times; 75 mm slides. They are available in 25-, 50-, and 100-slide capacities. Polypropylene versions are autoclavable and suitable for sterilized workflows, while fiberboard or ABS versions are typically used for room-temperature archival storage and transport.
Color Coding and Sample Identification
Color-coded storage boxes are widely used in biobanking and high-throughput laboratories to quickly differentiate sample groups without opening boxes or reading labels at freezer temperatures. Common systems include multiple lid colors paired with alphanumeric grids inside the box, enabling precise sample tracking and retrieval in large inventories.
&nbsp;
<h2 data-section-id="1jl751w" data-start="4067" data-end="4092">Specifications Context</h2>
&nbsp;
Modern polycarbonate cryogenic storage boxes are engineered for extreme temperature stability, typically rated from &ndash;196 &deg;C to +121 &deg;C, allowing use across liquid nitrogen vapor phase storage, &ndash;80 &deg;C freezers, and autoclave sterilization cycles. Cardboard freezer boxes are coated to resist moisture ingress and are optimized for cost-efficient high-density storage in ultra-low temperature environments.
The 81-place (9&times;9 grid) polycarbonate cryobox remains the standard format in most biorepositories and clinical research facilities due to its compatibility with SBS footprint freezer systems and automated inventory tracking workflows. These systems are widely used in genomics, cell banking, and pharmaceutical research environments.

Cell Scrapers

<h2 dir="ltr"> What are Cell Scrapers?</h2>
 Cell scrapers are sterile, single-use disposable tools with a polystyrene handle and a free-rotating polyethylene blade used to mechanically detach and harvest adherent mammalian cells from the TC-treated surface of culture flasks, dishes, and multi-well plates when enzymatic detachment (trypsin, Accutase, Dispase) is not appropriate. The free-rotating blade mechanism allows the angle to be adjusted by applying gentle pressure on the handle &mdash; the blade twists to align with the vessel surface for consistent, complete cell removal across the full growth area. Choose the 13 mm blade for T25 and T75 flasks and multi-well plates; choose the 20 mm blade for T175, T225, and 100&ndash;150 mm dishes, where a wider blade reduces the number of passes needed to clear the full growth surface.

</ul>
<h2 dir="ltr"> How to Choose Cell Scrapers</h2>
 When to Use Cell Scrapers Instead of Trypsin Cell scraping is the correct harvesting method when:
<ol>
<li style="text-align: left;">Trypsinization damages the protein or surface marker of interest; scraping preserves surface antigens, including CD markers for flow cytometry and receptor proteins for biochemical assays.&nbsp;</li>
<li style="text-align: left;">The cell line does not detach effectively with trypsin (some primary cells, fibroblasts in dense monolayers, epithelial cells after extended culture)</li>
<li style="text-align: left;">Harvest must be complete and rapid for protein or RNA extraction protocols with RNase-sensitive targets, where trypsin incubation time introduces RNA degradation risk</li>
<li style="text-align: left;">The downstream assay uses cells in medium without trypsin carryover (some enzyme assays, reporter gene assays, and cell viability assays where trypsin activity in the sample affects results). </li>
</ol>
Blade Size by Vessel Format The 13 mm blade (catalog 710001, 220 mm handle) is designed for T25 and T75 flasks and multi-well plates (6-well through 24-well). The blade width covers approximately 1&ndash;1.5 passes across a T75 flask width for complete surface coverage. The 20 mm blade (catalog 710011, 280 mm handle) suits T175 and T225 flasks, 100 mm and 150 mm dishes, and any large-surface vessel where the wider blade reduces scraping passes needed and operator fatigue. Both blade sizes fit through the standard T-flask neck opening. Free-Rotating Blade Mechanism NEST Scientific cell scrapers use a free-rotating blade that pivots relative to the handle on a hinge mechanism. Applying gentle lateral pressure on the handle adjusts the blade angle, allowing it to maintain flush contact with the vessel floor during the scraping stroke &mdash; improving cell detachment yield compared to fixed-blade scrapers, where the blade angle may not match the vessel floor geometry. After the push stroke, rotating the handle slightly returns the blade to the correct alignment for the next stroke. Scraping Technique Add 1&ndash;2 mL of culture medium or PBS to the vessel before scraping to lubricate the surface and prevent cells from drying. Work systematically across the flask or dish in parallel overlapping strokes. For T-flasks, tilt the flask at 20&ndash;30&deg; to pool the cell suspension at the low end after scraping, then pipette out the suspension. Do not press excessively &mdash; scraping force sufficient to detach cells should not require grinding the blade into the vessel floor, which damages cells and the scraper. 
<h2 style="text-align: left;"> Specifications Context</h2>
 NEST Scientific cell scrapers (catalog 710001 and 710011) are manufactured with a polystyrene handle and polyethylene blade.

Centrifuge Tubes

<h2>What Are Centrifuge Tubes?</h2>
 Centrifuge tubes are cylindrical laboratory containers with caps that are used to separate, pellet, and store biological or chemical samples through centrifugal force. They are commonly made from polypropylene (PP) or polystyrene (PS) and are available in sizes ranging from small 0.5 mL microtubes to larger 50 mL conical tubes. These tubes are widely used for cell pelleting, protein precipitation, DNA and RNA extraction, tissue homogenate clarification, and long-term sample storage. Depending on the material, they can withstand temperatures from &minus;80 &deg;C to +121 &deg;C.
In short, the best centrifuge tube depends on your centrifuge rotor, required g-force, sample volume, and sterility needs.

&nbsp;
<h2>How to Choose Centrifuge Tubes</h2>
 Volume and Rotor Compatibility
Select a tube size that matches both your sample volume and centrifuge rotor. Microtubes ranging from 0.5&ndash;2 mL are commonly used in microcentrifuges and can typically handle speeds up to 20,000 &times; g. Midi tubes in the 5&ndash;10 mL range are suitable for intermediate sample volumes, while 15 mL and 50 mL conical tubes are commonly used in clinical, research, and preparative centrifuges.
Material: Polypropylene vs. Polystyrene
Polypropylene (PP) tubes offer excellent chemical resistance and can tolerate temperatures from &minus;80 &deg;C to +121 &deg;C. They are suitable for autoclaving and exposure to many laboratory solvents. Polystyrene (PS) tubes provide superior optical clarity, making it easier to visually inspect samples and liquid levels, but they have lower resistance to solvents and extreme temperatures.
Sterility and Contamination Control
Sterile centrifuge tubes are typically gamma- or E-beam-irradiated and certified free of RNase, DNase, and pyrogens. These tubes are recommended for RNA extraction, cell culture, and clinical applications where contamination must be minimized. Non-sterile tubes may still be RNase- and DNase-free and are often suitable for routine DNA work and general sample storage.
Cap Design
Attached screw caps help prevent cap mix-ups and sample contamination, especially in high-throughput laboratories. Separate caps can be quicker to open and may be preferred in workflows that require frequent access to samples. If tubes will be used with automated systems, cap dimensions should be verified for compatibility with liquid handling equipment.
Packaging Options
Racked tubes provide convenient organization and allow direct pipetting while the tubes remain in the rack. Bulk-bagged tubes offer a more economical option for laboratories that process large volumes of samples and already have tube storage systems in place.
<h2> Comparing Common Centrifuge Tube Types</h2>
 Microtubes (0.5&ndash;2 mL) are ideal for PCR preparation, microcentrifuge applications, and storage of small sample volumes. They can generally withstand centrifugal forces up to 20,000 &times; g.
Midi tubes (5&ndash;10 mL) are designed for intermediate sample volumes such as culture supernatants and can typically tolerate forces up to 16,000 &times; g.
Sterile 15 mL conical tubes are frequently used for cell pelleting, RNA extraction, and clinical sample processing, with typical ratings between 12,000 and 15,000 &times; g.
Sterile 50 mL conical tubes are commonly selected for larger-volume applications including tissue culture work, density gradient preparation, and large-scale sample processing.
Polystyrene conical tubes in 15 mL and 50 mL formats are often chosen when visual sample inspection is important and solvent exposure is minimal.
<h2> Specifications and Features</h2>
 Polypropylene centrifuge tubes from Globe Scientific and Nest Scientific are manufactured from USP Class VI virgin resin and do not contain plasticizers or processing additives. Sterile products are typically irradiated to achieve a sterility assurance level (SAL) of 10⁻⁶. Most 15 mL tubes feature graduation marks at 1 mL intervals, while 50 mL tubes are usually graduated every 5 mL. MBP offers both bagged and racked centrifuge tube formats, including 15 mL and 50 mL conical tubes as well as smaller microtube and midi tube options.

<h2 data-section-id="1f93yys" data-start="914" data-end="963">How to Choose From All Centrifuge Tube Formats</h2>
&nbsp;
Volume and Rotor Compatibility
Selecting the correct tube size is essential for safe and efficient centrifugation. Microtubes ranging from 0.5&ndash;2 mL are designed for microcentrifuges, while 5&ndash;10 mL midi tubes fit compatible benchtop centrifuge rotors. Larger 15 mL and 50 mL conical tubes are commonly used in clinical and research centrifuges. Always verify rotor compatibility before introducing a new tube format into your workflow.
Sterility Requirements
For sensitive applications such as RNA extraction, cell culture, and clinical diagnostics, sterile tubes certified free of RNase, DNase, and pyrogens are recommended. Non-sterile tubes can provide a cost-effective solution for routine DNA analysis, protein assays, and general sample storage where sterility is not critical.
Material Selection
Polypropylene tubes offer excellent durability, can be autoclaved at 121 &deg;C, and resist many laboratory chemicals and solvents. Polystyrene tubes provide superior transparency, making it easier to monitor liquid levels and sample contents, although they are less resistant to heat and solvents.
Packaging and Inventory Planning
Microtubes are commonly available in pack sizes ranging from 500 to 1,000 units, while 15 mL and 50 mL conical tubes are often supplied in cases of 500. Laboratories with consistent usage may benefit from establishing recurring purchase orders to ensure uninterrupted supply.

All Centrifuge Tubes

<h2 data-section-id="hcowtr" data-start="0" data-end="45">What Are 15 mL and 50 mL Centrifuge Tubes?</h2>
&nbsp;
15 mL and 50 mL centrifuge tubes are conical-bottom vessels in polypropylene (PP) or polystyrene (PS), the two most commonly used tube formats in research and clinical laboratories worldwide. The 15 mL tube is the standard for cell pelleting, RNA isolation, small-scale protein purification, and clinical sample preparation. The 50 mL tube handles larger culture volumes, gradient preparation, tissue homogenate clarification, and bulk precipitation steps. Both formats from Globe Scientific and Nest Scientific are rated to 12,000&ndash;15,000 &times; g in a supported rotor.
15 mL for cell and molecular workflows under 12 mL; 50 mL for culture volumes, gradients, and any prep where a 15 mL conical runs out of headroom.

<h2 data-section-id="1j0vxh6" data-start="772" data-end="821">How to Choose 15 mL and 50 mL Centrifuge Tubes</h2>
&nbsp;
Material: PP vs PS
Polypropylene tubes (Globe Scientific, Nest Scientific) are resistant to most organic solvents, stable from &minus;80 &deg;C to +121 &deg;C, and autoclavable. Polystyrene tubes offer greater optical clarity &mdash; the tube wall is transparent enough to read the sample meniscus and assess pellet quality without removing the tube from the rack. Choose PS when visual inspection is a workflow step; choose PP for all other applications.
Sterility Grade
Sterile tubes (gamma- or E-beam-irradiated, RNase-free, DNase-free, non-pyrogenic) are required for RNA work, primary cell culture, and clinical sample handling. Non-sterile, DNase/RNase-free tubes are appropriate and more cost-effective for DNA extractions, protein assays, and general preparative spins.
Cap Style: Flat-Top vs Plug-Seal
Flat-top screw caps (high-density polyethylene, HDPE) provide a flat writing surface for sample labeling and a double-threaded design that reduces cross-threading in high-throughput workflows. Plug-seal screw caps (HDPE or PP) create a secondary internal seal for leak-prone applications. Attached caps come pre-assembled on sterile tubes; separate caps are standard on non-sterile tubes.
Pack Format: Racked vs Bagged
Racked tubes (foam or PS rack, 50 &times; 15 mL or 25 &times; 50 mL per rack, 500 per case) allow direct pipetting without removing tubes and enable viewing of graduations without disturbing the rack. Bagged tubes (25 or 50 per bag, 500 per case) offer a lower cost per tube and suit labs with robotic liquid handlers or in-house racking systems.

<h2 data-section-id="1riycx1" data-start="904" data-end="950">How to Choose Large Volume Centrifuge Tubes</h2>
&nbsp;
250 mL vs 500 mL
Choose 250 mL tubes when process volumes per tube run 150&ndash;240 mL &mdash; overfilling beyond ~80% of rated volume risks spill and cap failure. 500 mL tubes are used for volumes from 300&ndash;480 mL, common in vaccine and viral vector production, large-scale mammalian cell culture harvest, and preparative density-gradient centrifugation. The 500 mL tube has a larger diameter (95 mm) and shorter height (146 mm) than the 250 mL tube (60 mm &times; 160 mm), requiring a different rotor adapter.
Support Cushions and Rotor Compatibility
Large volume centrifuge tubes require properly fitted rotor support cushions (typically made from polyetherimide or similar materials) unless the rotor is specifically designed for direct tube support. These cushions prevent tube wall deformation under centrifugal force. Without correct support, tube failure may occur. Compatibility between tubes, cushions, and rotor buckets must always be confirmed before use.
Cap Type: Plug-Seal vs Flat Screw Cap
Plug-seal screw caps made from high-density polyethylene (HDPE) provide an internal sealing mechanism that improves leak resistance during high-force centrifugation, especially with viscous or biohazardous materials. Flat screw caps are generally used for lower-risk applications involving mixing or storage. Large volume polypropylene tubes are typically supplied with plug-seal caps rated for reliable containment under pressure conditions.
Sterility and Certification
Sterile large volume centrifuge tubes are gamma-irradiated to achieve a sterility assurance level (SAL) of 10⁻⁶ and are required for applications such as viral vector production, vaccine manufacturing, and primary cell culture workflows. Non-sterile RNase-free and DNase-free tubes are suitable for chemical processing steps and downstream analytical procedures where sterility is not critical.

<h2 data-section-id="1njhdwk" data-start="971" data-end="1011">How to Choose 500 mL Centrifuge Tubes</h2>
&nbsp;
Rotor Compatibility First
500 mL centrifuge tubes require a compatible swing-bucket rotor system that can accommodate a 95 mm tube diameter along with appropriate PEI support cushions. Common compatible systems include Thermo Fisher TX-750 and equivalent swing-bucket rotor models. It is essential to confirm both rotor bucket compatibility and correct cushion part numbers before use.
Using 500 mL tubes without proper support cushions or in incompatible rotors can lead to tube deformation or failure even at relatively low centrifugal forces.
Sterility for Bioproduction Workflows
Sterile 500 mL centrifuge tubes are gamma-irradiated to a sterility assurance level (SAL) of 10⁻⁶ and are certified RNase-free, DNase-free, and non-pyrogenic. These are required for bioproduction applications such as viral vector manufacturing, vaccine production, and primary cell culture workflows.
Non-sterile tubes may be used for downstream processing steps, chemical precipitation, or other laboratory applications where sterility is not required.
Cap Integrity and Leak Prevention
500 mL tubes are equipped with HDPE plug-seal screw caps that create an internal compression seal within the tube neck. This design provides leak resistance up to 95 kPa (14 psi), which is important for handling biohazardous or high-risk samples such as BSL-2 cell lines or viral vectors.
Proper cap closure is critical before centrifugation; caps must be fully tightened without cross-threading to ensure safe operation.
Pack Size and Ordering Considerations
These tubes are typically supplied in packs of 5 tubes per bag and 8 bags per case, totaling 40 tubes per case. Because of the relatively low number of tubes per case compared to smaller formats, laboratories performing high-throughput bioprocessing often maintain standing purchase orders to avoid supply interruptions.

<h2 dir="ltr"> Key BioFactory Accessory Categories</h2>
 BioFactory Cap with Silicone Tube (CPC or Luer Connector) The BioFactory cap with silicone tube is the primary closed-transfer accessory: an adaptor cap that fits the narrow-mouth port of the BioFactory unit, pre-assembled with 80 cm of silicone tubing and a terminal connector &mdash; either a male CPC (clamped pressure connector / quick-connect) or a standard Luer lock &mdash; for coupling to peristaltic pumps, other BioFactory units, centrifuge tubes, or PETG media bottle assemblies. Two tubing I.D. &times; O.D. configurations are available: 1/4" I.D. &times; 3/8" O.D. and 3/8" I.D. &times; 5/8" O.D., covering standard peristaltic pump head bore sizes. The female sealing cap included with each assembly caps the connector between uses, maintaining sterility. Overcaps: Vented and Solid Overcaps are secondary dust and contamination barriers placed directly on top of the BioFactory adaptor caps during culture incubation. The vented overcap contains a 0.22 &micro;m hydrophobic breathable membrane, allowing gas exchange through the cap stack while blocking particles and microbial contamination &mdash; used during active shaker or orbital incubation when the unit's primary cap is an adaptor cap rather than a vented cap. The solid overcap provides an additional dust and contamination seal with no gas exchange &mdash; used for short-term storage or transport outside the incubator. SPT-50 Silicone Hose SPT-50 silicone hose (3/8" I.D. &times; 5/8" O.D., 50 inches / 15 meters) is the bulk tubing used to connect multiple BioFactory units in series, connect BioFactory ports to peristaltic pump heads, or extend the reach of the transfer cap assembly. SPT-50 tubing is manufactured from silicone, is individually wrapped and sterile, and passes dissolution testing per BPOG (BioPhorum Operations Group) criteria per NEST product documentation, supporting its use in biopharmaceutical production environments. Premium Accessory Package NEST offers a BioFactory Accessory Premium Package that includes 2 different adaptor caps, 1 hose clamp, 1 adaptor connector, 1 vent filter (50 mm), 1 additional hose clamp, and 15 m of SPT-50 silicone hose &mdash; all individually wrapped and sterile in a single kit. This package provides all components needed to set up a closed-system BioFactory media management workflow from a single kit, reducing the number of individual part orders required. Vent Filters for Gas Exchange Management For BioFactory units using adaptor caps rather than standard vented caps, 50 mm inline vent filters (0.22 &micro;m hydrophobic PTFE membrane) are installed on the air inlet/outlet tubing line to maintain sterile gas exchange during media addition, harvest, and incubation. The vent filter is rated for high flow rates without creating excessive back-pressure that would resist liquid movement through the system. Compatibility: Narrow-Mouth BioFactory Units Only All BioFactory accessory caps and tubing assemblies are designed exclusively for the narrow-mouth BioFactory configuration. Wide-mouth BioFactory units use standard wide-mouth vent and plug seal caps only; they are not compatible with accessory cap assemblies. Confirm that your BioFactory units have narrow-mouth ports before ordering the accessory cap set. 
<h2 dir="ltr"> Specifications Context</h2>
 NEST BioFactory&trade; accessory silicone tubing and cap assemblies are manufactured from USP Class VI silicone (TPE/silicone) and polycarbonate or PP cap bodies, individually wrapped and sterile. All components have passed dissolution testing per BPOG dissolution test criteria conducted by a certified third-party laboratory per NEST Scientific documentation. The standard Luer head connections conform to ISO 594 / GB/T 1962 for reliable compatibility with standard laboratory fittings. Vent filters use a 0.22 &micro;m hydrophobic PTFE membrane; overcaps use a 0.22 &micro;m hydrophobic membrane. NEST BioFactory accessories are carried by MBP alongside BioFactory units.

Latex Gloves

<h2>What are latex examination gloves?</h2>
&nbsp;
Latex examination gloves are single-use disposable hand protection items made from natural rubber latex (NRL), which is derived from the sap of the rubber tree (Hevea brasiliensis). They are designed to meet ASTM D3578 standards for strength, elasticity, fit, and barrier integrity.
Compared with synthetic alternatives like nitrile, latex gloves have a lower elastic stiffness, meaning they stretch more easily and conform closely to the shape of the hand. This gives them superior tactile sensitivity, which is why they are still widely used in precision laboratory work, dental procedures, surgical environments, and fine sample manipulation tasks. Most modern latex gloves are powder-free, using chlorination or polymer coatings to allow easy donning without contamination risks.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>
Powder-free latex gloves for reduced contamination risk and cleaner samples
</li>
<li>
Examination-grade latex gloves for versatile laboratory use and diagnostics
</li>
<li>
High-dexterity latex gloves for precise handling during intricate tasks
</li>
</ul>
&nbsp;
<h2>How to choose latex examination gloves</h2>
&nbsp;
Tensile strength and elongation
Latex gloves are tested under ASTM D3578, which requires high elasticity and durability. They must withstand significant stretching without tearing, ensuring reliability during pipetting, dissection, and clinical procedures. This high elongation capacity is one of the main performance advantages of latex over nitrile.
AQL and medical-grade standards
Medical-grade latex gloves typically have an AQL of 2.5 or lower, meaning very low acceptable defect rates. These are required for laboratory, clinical, and pharmaceutical applications involving biological or chemical exposure. Industrial-grade gloves with higher AQL values are not suitable for controlled or regulated environments.
Powder-free requirement
All laboratory latex gloves should be powder-free. Powdered versions are no longer appropriate for scientific or clinical use because they can contaminate cell cultures, PCR reactions, and sensitive analytical assays. Powder-free gloves use chlorination or polymer coatings instead of cornstarch powder.
Grip and surface texture
Latex gloves may be smooth or textured. Textured fingertips improve grip during wet procedures such as pipetting, centrifuge tube handling, or tissue manipulation. Smooth versions are easier to don but offer less grip in wet environments.
Latex allergy risk
Natural rubber latex contains allergenic proteins that can trigger reactions in sensitive individuals. Because of this, laboratories must assess allergy risk and ensure nitrile alternatives are available. Repeated exposure increases sensitization risk, so many facilities have shifted fully to nitrile.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Latex examination gloves are governed by ASTM D3578, which defines mechanical strength, elongation, and quality requirements. Additional standards such as ASTM D5712 and ASTM D6124 assess protein content and residual powder levels. Medical-grade latex gloves are regulated as Class II medical devices in many regions and require compliance documentation such as FDA 510(k) clearance for clinical use. As of 2026, powder-free latex gloves remain common in surgical, dental, and high-dexterity laboratory applications, although many general labs now prefer nitrile due to allergy considerations.

Nitrile Gloves

<h2 data-section-id="upfogw" data-start="0" data-end="38">What are nitrile laboratory gloves?</h2>
&nbsp;
Nitrile laboratory gloves are single-use disposable hand protection items made from nitrile butadiene rubber (NBR), a fully synthetic material that contains no natural rubber proteins. Because of this, they are inherently latex-free and are widely used as the standard glove type in modern research, clinical, pharmaceutical, and diagnostic laboratories.
They are designed to provide a strong balance between chemical resistance, puncture resistance, and tactile sensitivity. Compared to natural rubber latex, nitrile gloves are typically around three times more resistant to punctures at the same thickness. Most nitrile gloves used in laboratories are medical-grade with AQL &le; 2.5, meaning they meet strict quality control limits for defects and are suitable for regulated environments. ASTM D6319 defines their performance requirements, including minimum tensile strength, elongation, and barrier integrity.

<h2 data-section-id="1apuf9x" data-start="1144" data-end="1186">How to choose nitrile laboratory gloves</h2>
&nbsp;
Thickness and application
Nitrile gloves come in different thicknesses depending on the task. Thinner gloves (around 3 mil) are used for high-dexterity work such as pipetting, PCR setup, and delicate cell culture tasks where precision is important. Medium thickness gloves (4&ndash;5 mil) are the standard choice for general laboratory work, clinical diagnostics, and pharmaceutical handling because they balance protection and flexibility. Thicker gloves (6 mil and above) are used when handling stronger chemicals, hazardous reagents, or when additional puncture resistance is needed.
AQL grade
AQL (Acceptable Quality Level) indicates defect rate. Medical-grade nitrile gloves typically have an AQL of 2.5 or lower and are required for work involving biological samples, pathogens, or pharmaceutical materials. Industrial-grade gloves with higher AQL values are not suitable for regulated laboratory or clinical use.
Color selection
Nitrile gloves are available in different colors such as blue, black, and purple. Blue is the most common because it provides strong visibility and easy detection of tears or contamination. Black gloves are often used in industrial or chemical environments, while purple gloves are sometimes used in clinical settings to differentiate them from latex products. Color does not affect chemical protection or performance at the same thickness.
Chemotherapy and hazardous drug resistance
Some nitrile gloves are specifically tested under ASTM D6978 for resistance to chemotherapy drugs and hazardous pharmaceuticals. These are required in oncology, compounding pharmacies, and laboratories handling cytotoxic agents. Standard nitrile gloves without this certification should not be assumed to provide protection against these compounds.
Chemical resistance limits
Nitrile gloves provide good resistance to oils, alcohols, dilute acids, and many aqueous solutions. However, they are not suitable for strong solvents such as acetone, toluene, chloroform, or other highly aggressive organic chemicals. For those, specialized glove materials must be selected based on chemical compatibility charts.

Cover Glass

<h2 data-section-id="smj2kt" data-start="0" data-end="23">What Is Cover Glass?</h2>
&nbsp;
Cover glass (also called coverslips or cover slips) are ultra-thin glass slips placed over a specimen mounted on a microscope slide. They may be rectangular, square, or circular depending on the application. Their main function is to protect the specimen from contamination and physical damage while also creating a uniform optical surface for high-quality imaging.
A critical factor in cover glass selection is thickness, since microscope objectives are optically corrected for specific coverslip standards. The two most common grades are No. 1 (nominal 150 &micro;m, range 130&ndash;170 &micro;m) and No. 1.5 (nominal 175 &micro;m, &plusmn;15 &micro;m). In most modern microscopy systems, No. 1.5 cover glass is preferred, especially for high-numerical aperture (high-NA) objectives used in fluorescence and confocal microscopy. Using the wrong thickness can introduce spherical aberration and reduce image sharpness.

&nbsp;
<h2 data-section-id="5ihghg" data-start="910" data-end="938">How to Choose Cover Glass</h2>
&nbsp;
Thickness: No. 1 vs No. 1.5
No. 1.5 cover glass (175 &micro;m nominal) is the standard choice for most modern objectives because it matches the optical correction of high-NA lenses used in advanced imaging. No. 1 cover glass (150 &micro;m nominal) should only be used when the microscope objective is specifically designed or labeled for that thickness. Mismatching cover glass thickness and objective correction leads to image distortion and reduced resolution, particularly at higher magnifications.
Shape: Square, Rectangular, or Circular
Square coverslips (commonly 18 &times; 18 mm or 22 &times; 22 mm) are used for routine microscopy and tissue sectioning. Rectangular coverslips (such as 24 &times; 50 mm or 24 &times; 60 mm) are preferred for larger specimens like extended tissue sections or blood smears. Circular coverslips are used in specialized applications such as glass-bottom culture dishes and live-cell imaging systems.
Surface Quality: Standard vs Pre-Cleaned vs Low-Autofluorescence
Standard cover glass may require cleaning before use, while pre-cleaned coverslips are ready for immediate mounting and help reduce particulate artifacts that interfere with imaging. For fluorescence and advanced imaging applications, low-autofluorescence or precision-grade cover glass is preferred because it reduces background signal and improves contrast and signal-to-noise ratio.
Quantity and Packaging
Cover glass is typically supplied in packs based on count or weight, with common packaging sizes ranging from 100 to 500 pieces per box. High-throughput laboratories often purchase in case quantities for cost efficiency and consistent supply management. MBP can assist with selecting appropriate pack sizes based on laboratory workflow and volume requirements.
&nbsp;
<h2 data-section-id="1jl751w" data-start="3288" data-end="3313">Specifications Context</h2>
&nbsp;
Cover glass thickness is defined by industry standards rather than exact uniform measurement: No. 1 typically ranges from 130&ndash;170 &micro;m (nominal 150 &micro;m), while No. 1.5 typically ranges from 160&ndash;190 &micro;m (nominal 175 &micro;m). High-precision No. 1.5H cover glass offers tighter tolerances (approximately &plusmn;5 &micro;m) and is used in high-resolution confocal and super-resolution microscopy where optical consistency is critical. Standard borosilicate cover glass has a refractive index of approximately 1.515&ndash;1.523, which matches the correction assumptions of most microscope objectives.

Cryo Boxes

<h2>What Are Cryo Boxes?</h2>
&nbsp;
Cryo boxes are lidded, gridded storage containers designed to organize cryogenic vials, microcentrifuge tubes, and centrifuge tubes inside ultra-low temperature (ULT) freezers at &minus;80&deg;C, vapor-phase liquid nitrogen refrigerators (&minus;150 to &minus;190&deg;C), and cryogenic dewars. The two primary materials are water-resistant coated cardboard (economical, single-use) and rigid polycarbonate or polypropylene (reusable, autoclavable, transparent). Standard well configurations&mdash;25 (5&times;5), 81 (9&times;9), and 100 (10&times;10)&mdash;in 2-inch and 3-inch box heights match common cryogenic vial sizes. The alphanumeric grid on the lid helps with sample tracking in LIMS systems. Cardboard cryo boxes are vapor-phase LN2 rated only; polycarbonate is required for autoclave use or liquid-phase LN2 immersion.
&nbsp;
<h2>What you will find:</h2>
&nbsp;

&nbsp;
<h2>How to Choose Cryo Boxes</h2>
&nbsp;
Material: Cardboard vs. Polycarbonate vs. Polypropylene
Cardboard cryo boxes are economical and used for long-term storage at &minus;80&deg;C or vapor-phase LN2. They are single-use and not autoclavable. Polycarbonate (PC) boxes are durable, transparent, and autoclavable at 121&deg;C, making them suitable for frequent handling. Polypropylene (PP) boxes also tolerate autoclaving and offer higher chemical resistance than PC. Choice depends on reuse frequency and sterilization needs.
Well Count and Vial Size
81-well (9&times;9) boxes fit standard 1.8&ndash;2.0 mL cryogenic vials up to ~13 mm outer diameter. 100-well (10&times;10) boxes are used for smaller 1.2&ndash;1.5 mL vials and microcentrifuge tubes up to ~12 mm OD. Always match vial diameter with box well size before ordering.
Box Height: 2-Inch vs. 3-Inch
2-inch boxes are standard for 1&ndash;2 mL cryovials and are most commonly used in biobanking. 3-inch boxes are for larger 3&ndash;5 mL vials and certain centrifuge tubes where extra depth is required.
LN2 Phase Compatibility
Both cardboard and hard-wall boxes can be used in vapor-phase LN2. Only polycarbonate or polypropylene boxes should be used for liquid-phase LN2 because cardboard can break down when submerged.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Cryo boxes are typically rated from &minus;196&deg;C to +121&deg;C depending on material. Cardboard is suitable for vapor-phase LN2 only, while hard-wall plastic boxes can handle more demanding workflows. Proper selection depends on vial size, storage temperature, and how frequently samples are accessed.
