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.

&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.

Funnels

<h2>What Are Laboratory Weighing Funnels?</h2>
&nbsp;
Laboratory weighing funnels are single-use antistatic polypropylene (PP) funnels specifically designed for the weighing-and-transfer step in analytical chemistry, pharmaceutical weighing, and sample preparation workflows. Unlike standard powder funnels, weighing funnels have one flat side that allows the funnel to rest stable on a balance pan during mass measurement, and a conical stem sized to the neck of a specific volumetric flask volume. After the sample mass is recorded, the funnel inserts directly into the flask neck, and the sample is transferred by tipping or rinsing&mdash;providing quantitative, loss-free transfer into narrow-neck vessels. Available in extra small (fits microtubes and 5&ndash;20 mL flasks) through extra-extra-large (fits 1000 mL+ vessels). Antistatic weighing funnels are single-use; washing removes the antistatic treatment. Reusable funnels needing autoclave sterilization should be standard polypropylene powder funnels, not antistatic weighing funnels.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Powder funnels with wide stems for smooth solid transfer</li>
<li>Long-stem funnels for controlled pouring into narrow containers</li>
<li>Short-stem funnels for faster liquid transfer</li>
<li>Filter funnels for use with standard filter paper</li>
<li>Chemical-resistant plastic funnels for lab compatibility</li>
<li>Disposable funnels for single-use workflows</li>
</ul>
&nbsp;
<h2>How to Choose Laboratory Weighing Funnels</h2>
&nbsp;
Match Size to Flask Neck
The critical specification for a weighing funnel is the stem outer diameter relative to the flask neck inner diameter. Extra small fits 96-well microtubes and 5&ndash;20 mL volumetric flasks; small fits 20&ndash;50 mL; medium fits 50&ndash;200 mL; large fits 200&ndash;500 mL; extra large fits 500&ndash;1000 mL. A funnel that is too wide will not insert and will spill during transfer&mdash;when in doubt, choose one size smaller.
Disposable Antistatic vs. Reusable PP
For analytical weighing of fine powders, use disposable antistatic PP funnels&mdash;the antistatic surface dissipates charge that causes powder adhesion. For bulk transfer of coarse materials or liquids where static is not an issue, standard reusable polypropylene powder funnels (autoclavable at 121&deg;C, large-bore stem) are more economical and can be sterilized between uses.
Assorted vs. Individual Packs
Assorted packs covering extra small through extra large provide flexibility when flask sizes vary across experiments and reduce the number of individual SKUs to manage. Individual packs are more economical when only one funnel size is used at high volume.
Flat-Side Stability
All antistatic weighing funnels have one flat side on the funnel body. This flat face allows the funnel to rest stably on a balance pan without rolling during the weighing step before transfer&mdash;a design feature absent on standard laboratory funnels.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Antistatic polypropylene weighing funnels achieve antistatic performance through a surface additive incorporated during molding; this is a surface treatment rather than a bulk polymer property. The flat side is designed to rest on a balance pan while keeping the stem vertical for direct transfer into volumetric flasks. As of 2026, these funnels are standard in pharmaceutical QC and analytical chemistry labs for gravimetric transfer workflows compliant with USP procedures.

Microscope Accessories

<h2>What Are Microscope Accessories?</h2>
&nbsp;
Microscope accessories are supplementary components that configure, upgrade, or expand the function of a base microscope beyond its standard out-of-the-box specification. They fall into several categories: imaging accessories (cameras, camera adapters, camera relay lenses) for digital image capture and video documentation; optical accessories (additional or replacement objective lenses, eyepieces, auxiliary objectives for stereo microscopes) that change magnification or improve optical quality; fluorescence accessories (filter cube sets, LED fluorescence modules, mercury lamp adapters, UV/visible filter wheels) for adding or expanding fluorescence capability; stage accessories (multiwell plate holders, slide holders, cross-roller stages, motorized XY stage inserts, focus drives) that expand sample handling; illumination accessories (fiber optic illuminators, ring lights, polarizers, dark-field condensers) for alternative contrast methods; and maintenance and consumable accessories (immersion oil, lens paper, slide cleaning kits, replacement illuminator bulbs). Because accessory designs are instrument-specific (not all cameras, objectives, or stage inserts are universally compatible), identify the microscope model and manufacturer before ordering any accessory. Always identify the exact microscope model and manufacturer before ordering any accessory; thread standards, bayonet mounts, tube lengths, and connector formats vary significantly between brands and generations.

</ul>
&nbsp;
<h2>How to Choose Microscope Accessories</h2>
&nbsp;
Digital cameras and adapters
Microscope cameras attach to the trinocular port (or monocular camera port on some models) via a C-mount camera adapter with an integrated relay lens. The relay lens magnification (typically 0.35x, 0.5x, or 1x) determines the effective field of view on the camera sensor. Choose a CMOS camera with 5 to 20 megapixels for brightfield documentation and routine fluorescence; scientific CMOS (sCMOS) or cooled CCD cameras for low-light fluorescence quantification. Confirm the camera software is compatible with the microscope's control software (if motorized).
Objective lenses
Replacement or additional objectives must match the microscope's objective thread standard and tube length (160 mm finite or infinity-corrected). Never mix finite-optics and infinity-corrected objectives on the same nosepiece; the image-forming properties are incompatible. Plan-apochromat objectives in the same brand family as the microscope are the safest choice for optical performance and parfocality with the existing objective set.
Fluorescence filter cube sets
Fluorescence filter cubes contain an excitation bandpass filter, a dichroic mirror, and an emission bandpass filter, which are the three components that define which fluorescent dye or protein is imaged. Common filter sets: DAPI (Ex 360/40, Di 400LP, Em 460/50); FITC/GFP (Ex 470/40, Di 495LP, Em 525/50); TRITC/mCherry (Ex 550/25, Di 565LP, Em 605/70); Cy5 (Ex 620/60, Di 660LP, Em 700/75). Confirm the cube block type (Olympus U-MF2, Nikon B-2A, Zeiss 38HE, or other) matches the filter cube turret of the specific microscope model.
Stage inserts and sample holders
Stage inserts expand sample compatibility: multiwell plate holders (96-well, 384-well, 6-well) for high-content imaging; glass-bottom dish holders for live-cell imaging with oil-immersion objectives; slide holder adapters for larger or smaller slide formats; and universal stage inserts for non-standard containers. Confirm the stage insert dimensions match the microscope's mechanical stage cutout and that the height profile is compatible with the condenser working distance for transmitted illumination.
LED fluorescence modules
LED fluorescence modules replace or augment mercury arc lamps in the fluorescence port of existing microscopes, providing individual LED channels for DAPI, GFP, TRITC, and Cy5 excitation. LED upgrades are available as bolt-on add-ons for many research-grade inverted and upright microscopes and significantly extend the fluorescence illumination service life from 200 to 300 hours (mercury) to 50,000+ hours (LED). Confirm the LED module's mounting standard and control interface (USB, TTL, or software-triggered) is compatible with the microscope.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Immersion oil for oil-immersion microscopy must match the refractive index for which the objective is designed; standard immersion oil has a refractive index of 1.515 at 23 degrees C (per ASTM and DIN standards). Using oils with different refractive indices introduces spherical aberration. Viscosity matters for the application: low-viscosity oils (Type A, 150 mPas) spread easily and are used for fast scanning; high-viscosity oils (Type B, 1250 mPas) resist creep at elevated stage temperatures. Clean all residual immersion oil from objectives immediately after each use with lens tissue dampened with appropriate lens cleaning solution; dried immersion oil is difficult to remove and can permanently damage the objective coating.&nbsp;

Benchtop Recappers

<h2>What Are Benchtop Recappers?</h2>
&nbsp;
Benchtop recappers are compact, motor-driven instruments that automate the opening and sealing of screw-cap or push-cap sample storage tubes in standard rack formats (24-, 48-, and 96-position). They are used in biobanks, clinical sample management laboratories, genomics core facilities, and other environments where large numbers of cryogenic or ambient-storage tubes require repeated capping and decapping. Manual recapping at scale is a leading contributor to repetitive strain injury (RSI) in high-throughput sample preparation workflows.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>RFID-enabled racks for reliable sample tracking</li>
<li>SBS-format compatibility for standardized laboratory workflows</li>
<li>Automated capper and decapper functionality for improved efficiency</li>
<li>Secure and consistent tube sealing with CT&trade; caps</li>
<li>Compact benchtop designs that maximize laboratory space</li>
</ul>
&nbsp;
<h2>How to Choose a Benchtop Recapper</h2>
&nbsp;
Throughput Format (24 / 48 / 96)
Select the rack format that matches your primary tube storage system. A 96-position automated device can process a full rack in under 60 seconds, while a semi-automated 8-channel row decapper can complete a single row in under 5 seconds, making it suitable for moderate-throughput laboratories without full-rack automation requirements.
Cap Type Compatibility
Confirm whether your tubes use screw caps or push caps, as each requires a different capping mechanism. Screw-cap recappers apply a preset torque value, typically between 1 and 5 N&middot;cm, and automatically stop when the proper seal is achieved. Push-cap systems rely on controlled vertical force. Multi-format adapters can support several tube brands within a single instrument.
Standalone vs. Integrated Systems
Standalone benchtop recappers are suitable for laboratories without dedicated automation infrastructure, while integrated models connect with Hamilton, Tecan, or Beckman Coulter workstations through SBS-format racks and software interfaces. Laboratories requiring LIMS connectivity and sample traceability should consider systems with built-in 1D and 2D barcode scanning capabilities.
Tube Diameter Range
Most automated recappers support standard collection tubes ranging from 13 to 16 mm in diameter and 75 to 115 mm in height. Verify compatibility with your cryovials or specialty microtubes before purchasing, particularly when using proprietary storage systems.
Maintenance Requirements
Pneumatics-free designs eliminate the need for compressed-air infrastructure and generally reduce maintenance demands. Pneumatic systems may offer high performance but require periodic servicing and access to a laboratory air supply.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Rack format (24, 48, or 96 tubes) establishes the maximum throughput of a benchtop recapper. Torque settings must be compatible with the selected tube and cap combination, since excessive torque can crack caps while insufficient torque can lead to evaporation or contamination. SBS-format compliance ensures interoperability with industry-standard racks and automated workflows. As of 2026, many benchtop recappers incorporate IoT-enabled monitoring, barcode integration, and LIMS connectivity to improve sample traceability and reduce manual documentation requirements in high-throughput laboratories.

Cryogenic Vials

<h2>What Are Cryogenic Vials?</h2>
&nbsp;
Cryogenic vials are specialized screw-cap laboratory containers manufactured from cryogenic-grade virgin polypropylene (PP) and designed to withstand extreme temperatures ranging from &minus;196&deg;C in liquid nitrogen storage to +121&deg;C during steam autoclaving. They serve as the primary storage vessel for biological materials requiring long-term preservation, including cell lines, serum, plasma, blood samples, DNA, RNA, microbial cultures, and other biospecimens. Common vial capacities include 1.2 mL, 1.5 mL, 1.8 mL, 2 mL, 3 mL, and 5 mL, with the 2 mL format being the most widely used standard for cell culture and biobanking applications. Most cryogenic vials feature leak-resistant screw caps with silicone sealing gaskets and dedicated writing areas for sample identification. For storage in liquid nitrogen, it is important to use vials specifically certified for cryogenic applications, as standard laboratory tubes are not designed to tolerate temperatures as low as &minus;196&deg;C.

</ul>
&nbsp;
<h2>How to Choose Cryogenic Vials</h2>
&nbsp;
Thread Type: Internal vs. External
Thread design influences both contamination control and workflow compatibility. Internal-thread vials position the sealing mechanism inside the neck of the vial, reducing the external surface area exposed to contaminants and making them a common choice for cell culture and biosafety-sensitive applications. External-thread vials place the threads on the outside of the vial neck, maximizing internal storage volume and improving compatibility with automated capping, decapping, and robotic handling systems. Laboratories using automated biobanking workflows often prefer external-thread formats.
Volume Selection
Vial capacity should match the intended sample type and storage requirements. The 1.8&ndash;2.0 mL size is commonly used for cell lines, serum aliquots, and general biospecimen storage because it fits standard cryogenic storage boxes. Smaller 1.2 mL formats support high-density storage of limited-volume samples, while larger 3&ndash;5 mL vials are suitable for tissue specimens, bacterial glycerol stocks, and applications requiring larger sample volumes.
Sterility and Purity Certification
For cell culture, molecular biology, and clinical research applications, cryogenic vials should be supplied with certifications confirming they are RNase-free, DNase-free, non-pyrogenic, and endotoxin-free. Many laboratories also prefer gamma-sterilized vials, which reduce contamination risk and eliminate the need for additional sterilization before use. Traceable lot documentation and certificates of conformity are often required in regulated environments.
Self-Standing vs. Round Bottom Designs
Self-standing cryogenic vials feature a molded base that allows them to remain upright on laboratory benches without additional support, reducing the risk of spills during sample handling. Round-bottom designs are compatible with a broader range of storage racks and cryogenic systems but generally require a rack or holder during bench-top use. The choice largely depends on laboratory workflow and storage equipment.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Cryogenic vials are typically manufactured from high-purity polypropylene because of its excellent durability and resistance to ultra-low temperatures. Products intended for liquid nitrogen immersion should carry explicit certification for liquid-phase storage, as some vials are approved only for vapor-phase applications. Vial dimensions, particularly outer diameter, determine compatibility with freezer boxes, racks, and automated storage systems, so measurements should be confirmed before mixing products from different manufacturers. Modern biobanking facilities increasingly use externally threaded, 2D-barcoded cryogenic vials integrated with laboratory information management systems (LIMS) to improve inventory tracking, sample traceability, and large-scale repository management.

Test Tubes

<h2 dir="ltr">What are Test Tubes?</h2>
 Test tubes for laboratory use are open-ended, cylindrical glass or plastic tubes used to hold, mix, incubate, and heat liquid and solid samples across a broad range of applications: bacteriological culture, tissue culture, clinical chemistry, serological assays, immunology, and general sample processing. Choose borosilicate glass for reusable, high-temperature, or chemically demanding applications; choose polystyrene disposable 12&times;75 mm tubes for flow cytometry and colorimetric assays; choose polypropylene capped tubes for microbial culture with anaerobic or gas-generating organisms.

<h2 dir="ltr">How to Choose Test Tubes</h2>
 Material: Glass vs. Polypropylene vs. Polystyrene Borosilicate glass 3.3 (ASTM E438 Type I, Class B) test tubes withstand direct flame, autoclave sterilization at 121 &deg;C, and most solvents, acids, and bases. They are reusable and autoclavable, making them cost-effective over high-volume laboratory runs. Polystyrene (PS) disposable tubes offer outstanding optical clarity for flow cytometry (FACS), cell counting, and OD-based colorimetric assays, but cannot be autoclaved and should not be used with aromatic solvents or strong acids. Polypropylene (PP) tubes are chemically resistant, autoclavable, and available with screw caps for anaerobic culture or gas-generating reactions. Rimmed vs. Rimless Rimless test tubes (fire-polished ends) allow easier insertion of rubber or silicone stoppers and are preferred for plugging with cotton wool for microbial culture. Rimmed tubes have a flared lip that facilitates pouring and is compatible with spring-metal tube closures. Confirm your closure type before ordering in bulk. Size and Volume The most common test tube dimensions in clinical and research labs: 12&times;75 mm: ~5 mL capacity; standard for flow cytometry, FACS, serology 13&times;100 mm: ~10 mL; general culture and chemistry 16&times;100 mm: ~14 mL; culture and chemistry 16&times;125 mm: ~17 mL; microbiological culture 18&times;150 mm: ~25 mL; larger-volume digests and culture Wall thickness of 1.2 mm (light wall, borosilicate 3.3) is the standard for general lab use; heavy-wall versions are used for digestions and applications involving vacuum or pressure. Sterile vs. Non-Sterile Sterile borosilicate glass culture tubes (individually wrapped or bulk-sterilized) are required for microbial culture, cell culture, and any application where contamination would invalidate the result. Non-sterile tubes are adequate for chemistry, spectroscopy, and other abiotic applications. Disposable PS tubes from Corning (PYREX&trade;) and Globe Scientific are supplied sterile or non-sterile; confirm the specification on the lot certificate. 
<h2 dir="ltr"> Specifications Context</h2>
 Borosilicate glass 3.3 test tubes have a linear thermal expansion coefficient of 3.3 &times; 10⁻⁶ K⁻&sup1;, providing resistance to thermal shock from room temperature to 300 &deg;C (direct flame) and from 0 to 121 &deg;C (autoclave cycles). Light-wall tubes (1.2 mm uniform wall thickness) provide the standard for general laboratory use; heavy-wall variants (2.0 mm) are used for digestion vessels and pressurized applications. Corning PYREX&trade; disposable round-bottom rimless glass tubes for tissue culture conform to ASTM standards and are the reference format for bacteriological serology and cell wash procedures.

Sample Cups

<h2 dir="ltr">What are Automation Sample Cups?</h2>
 Automation sample cups (also called analyzer sample cups, autosampler cups, or J-cups) are small-volume polystyrene or polypropylene vessels designed to hold aliquoted patient specimens for direct loading into automated clinical chemistry analyzers, immunoassay platforms, hematology analyzers, and ICP-MS/ICP-OES spectrometers. They are used when an analyzer's primary tube handler cannot directly aspirate from a standard 15 mL or 50 mL collection tube&mdash;typically because the sample volume is insufficient, a diluted aliquot is required, or a specific cup geometry is mandated by the instrument's sampling needle. Globe Scientific offers the largest selection of alternate (OEM-equivalent) sample cups for laboratory analyzers, providing significant per-cup savings versus manufacturer-supplied consumables. Choose analyzer sample cups by instrument model first&mdash;dimensional compatibility is non-negotiable&mdash;then optimize for material (PS for optical clarity, PP for chemical resistance) and volume.

<h2 dir="ltr"> How to Choose Automation Sample Cups</h2>
 Instrument Compatibility: Dimensional Match is Mandatory Automation sample cups must match the exact outer diameter, height, and cup-bottom geometry specified by the instrument manufacturer. A cup that is 0.5 mm too wide or too narrow will not seat correctly in the autosampler rotor, causing aspiration failures, pipetting errors, or instrument alarms. Globe Scientific engineers and validates each alternate cup to OEM specifications for named analyzer platforms; confirm the instrument model against the catalog's compatibility list before ordering. Volume: 0.5 mL vs. 1.5 mL vs. 2.0 mL 0.5 mL cups (13.55 &times; 24.50 mm, polystyrene) are used on chemistry analyzers including Beckman CX series, Alpha Wassermann, Bio-Chem Labs, and DPC Immulite platforms. 1.5 mL cups (13.8 &times; 22.60 mm) are used on BioMerieux AG-2/ASCA and MLA 1600C platforms. Larger 2.0 mL cups are used on Roche cobas and Horiba ABX platforms. The minimum working volume of the cup must exceed the analyzer's dead volume (typically 150&ndash;400 &micro;L) plus the required sample volume. Material: Polystyrene vs. Polypropylene Polystyrene (PS) sample cups provide excellent optical clarity for colorimetric-based analyzers that photometrically read the cup contents and have low protein adsorption for routine chemistry analytes. Polypropylene (PP) cups are used when the sample contains organic solvents, strong acids (trace element analysis), or when acid-wash protocols are required for ICP-MS autosampler systems. MoldPro and Globe Scientific PP autosampler cups for PerkinElmer, Agilent, and Shimadzu ICP systems are manufactured from virgin PP with ultra-low metal content verified by ICP-MS lot testing. With or Without Caps/Inserts Sample cups with caps are used when the aliquot must be sealed to prevent evaporation or cross-contamination during batch loading. Insert cups (smaller inner cup that sits inside a standard tube) allow aliquoted samples to be loaded directly without relabeling &mdash; a common efficiency gain in high-volume core labs. Confirm whether your instrument's autosampler accepts capped cups or requires open-top formats. ICP-MS vs. Clinical Chemistry Applications ICP-MS autosampler cups require certified ultra-low metal content (verified by ICP-MS at ppb level), manufactured from virgin PP without metal-containing additives, dyes, or fillers. Standard PS clinical chemistry cups contain low-level metal additives from colorants and should not be used for trace element or heavy metal analysis. Always use metal-free certified cups for any elemental analysis application. 
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific analyzer sample cups are manufactured to exact OEM specifications and provide equivalent precision and optical properties to original manufacturer cups. PS cups have optical clarity with &ge;90% light transmission in the visible spectrum, required for photometric analyzers. PP ICP-MS autosampler cups meet ultra-low metal content specifications: typically &lt;1 ppb for Fe, Zn, Cu, Pb, Mn, and other analytes commonly measured in trace element panels. Cup dimensions are held to &plusmn;0.1 mm tolerance on O.D. to ensure consistent seating in autosampler rotors. As of 2026, Globe Scientific is the most widely stocked alternate analyzer consumable brand through lab distributors, including MBP, offering per-cup savings of 20&ndash;40% versus OEM pricing for high-volume clinical labs.

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>

&bull; Standard cryo boxes for cryogenic vial storage &bull; Freezer storage boxes for ultra low temperature use &bull; Cardboard cryo boxes for cost effective storage &bull; Polypropylene cryo boxes for durability and reuse &bull; Grid format boxes for easy sample organization &bull; Hinged lid cryo boxes for quick access &bull; Color coded storage boxes for sample identification &bull; Cryo storage boxes for 1.5 mL and 2.0 mL vials
&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.

Centrifuge Bottles

<h2 data-section-id="1x7fdl3" data-start="0" data-end="31">What Are Centrifuge Bottles?</h2>
&nbsp;
Centrifuge bottles are large-volume vessels made from polypropylene copolymer (PPCO) or polypropylene (PP), designed for low- to moderate-speed centrifugation of biological and chemical samples. Available in volumes ranging from 250 mL to 1,000 mL, these bottles feature a bottle-shaped body with either a flat or rounded bottom and are designed to fit swing-bucket and fixed-angle rotors used in preparative centrifuges and floor-standing centrifuge systems.
They are commonly used for large-scale mammalian cell culture harvesting, ammonium sulfate protein precipitation, bacterial cell pelleting, density-gradient separations, and biopharmaceutical process clarification where standard centrifuge tubes do not provide sufficient capacity.
Use centrifuge bottles when processing volumes exceed 250 mL per run and your centrifuge rotor is designed for bottle-format vessels. Always verify fill requirements and rotor compatibility before use.

&nbsp;
<h2 data-section-id="152gqj6" data-start="991" data-end="1026">How to Choose Centrifuge Bottles</h2>
&nbsp;
Material: PPCO vs PP
Polypropylene copolymer (PPCO) centrifuge bottles offer enhanced flexibility and impact resistance compared to standard polypropylene. This helps reduce the risk of cracking during repeated autoclaving cycles or accidental handling impacts. PPCO bottles are translucent, allowing users to visually monitor samples without removing bottles from the rotor.
Standard polypropylene bottles provide similar chemical resistance but are generally more rigid. Selection should be based on the application's mechanical and chemical requirements.
Volume Selection: 250 mL, 500 mL, and 1,000 mL
250 mL centrifuge bottles are typically used for process volumes between 200 and 225 mL and are suitable for medium-scale laboratory workflows.
500 mL centrifuge bottles accommodate process volumes of approximately 400&ndash;450 mL and are commonly used for larger culture harvests and clarification procedures.
1,000 mL centrifuge bottles are designed for high-volume applications including bacterial fermentation harvesting, large-scale density-gradient preparation, and manufacturing-scale clarification processes. Because of their larger size, these bottles generally have lower maximum centrifugal force ratings than smaller formats.
Cap Type: Standard Screw Cap vs Sealing Cap
Standard polypropylene screw caps provide reliable leak protection during routine centrifugation and storage applications.
Sealing cap assemblies incorporate additional gasket-based sealing systems that improve containment during higher-speed centrifugation and when handling biohazardous materials. These sealing systems are commonly used when aerosol containment or enhanced sample security is required.
Rotor and Adapter Compatibility
Centrifuge bottles must be matched to compatible rotor systems and adapters. Bottle dimensions, neck designs, and rotor requirements vary by manufacturer and volume. Before purchasing, laboratories should verify compatibility between the bottle, rotor, and any required adapters to ensure safe operation.
Fill Level Requirements
Proper fill volume is critical for safe centrifugation. Most centrifuge bottles should be filled to at least 80% of their total capacity to prevent excessive stress on the bottle walls during centrifugation. Underfilled bottles may deform or collapse under centrifugal force. For some larger formats, maximum fill recommendations may also apply and should be verified with manufacturer specifications.
&nbsp;
<h2 data-section-id="1mxgh1c" data-start="3525" data-end="3561">Compare Centrifuge Bottle Formats</h2>
&nbsp;
250 mL PPCO centrifuge bottles are manufactured from polypropylene copolymer and are typically supplied in packs of four bottles per case. When used with appropriate sealing cap assemblies, they can support significantly higher centrifugal forces than standard-cap configurations.
500 mL PPCO centrifuge bottles provide increased sample capacity for larger-volume processing applications. These bottles are commonly supplied with standard screw caps and are packaged in case quantities of four bottles.
1,000 mL PPCO centrifuge bottles are intended for large-scale harvesting and clarification workflows. Although they provide the highest volume capacity, they generally operate at lower maximum centrifugal force ratings than smaller bottle formats. Packaging typically consists of four bottles per case.
