Sample Storage Container

<h2 dir="ltr">What are Urine Collection Products?</h2>
 Urine collection products for laboratory use are containers and preservative systems designed to collect, stabilize, and transport urine specimens for urinalysis (UA), urine culture (C&amp;S), nucleic acid-based testing (NAAT for STIs), cell-free DNA (cfDNA) liquid biopsy, and 24-hour timed collections. Formats include sterile cups (30&ndash;60 mL), preservative tubes (5&ndash;50 mL), vacuum-draw urine transfer tubes, 24-hour collection containers (2&ndash;3 L), and preservative-prefilled devices for ambient-temperature stabilization of DNA, RNA, and proteins. Choose urine collection products with an active preservative when specimens cannot be processed within 2 hours of collection, when samples must be shipped to a centralized lab, or when nucleic acid integrity over 24+ hours is required.

<h2 dir="ltr"> How to Choose Urine Collection Products</h2>
 Application: Culture vs. NAAT vs. Nucleic Acid Research For culture (C&amp;S), use sterile cups or boric acid preservative tubes. For NAAT (STI panels for Chlamydia, Gonorrhea), use sterile cups or manufacturer-validated transfer tubes; confirm with your platform's IFU (e.g., Hologic Aptima Combo 2 uses a specific urine transport tube). For nucleic acid research (cfDNA, RNA, protein), use dedicated urine preservative tubes (Norgen, Streck) that stabilize analytes for up to 72 hours at room temperature. Volume: Random vs. 24-Hour Collection Random midstream urine (10&ndash;30 mL) is adequate for urinalysis, culture, and NAAT. Timed 24-hour collections (total volume 500&ndash;3000 mL) require large-volume containers with the appropriate preservative for the ordered panel. Mixing 24-hour containers with different preservatives is a common error&mdash;verify the correct preservative type with the laboratory before dispensing to the patient. Preservative Compatibility Boric acid tubes maintain bacterial counts for culture up to 24 hours at room temperature. Boric acid is NOT compatible with NAAT workflows&mdash;it inhibits PCR. For NAAT, use plain sterile containers or manufacturer-specific transfer tubes. For liquid biopsy cfDNA, Streck Cell-Free DNA Urine Preservative maintains cell integrity and prevents genomic DNA contamination for up to 72 hours. Sterility All urine containers intended for culture must be certified sterile. Containers for NAAT must be certified DNase-free and RNase-free to prevent nucleic acid contamination from the container. Confirm sterility and nuclease-free certification in the manufacturer's datasheet before use in molecular workflows. Automated Compatibility For high-throughput labs using automated urine analyzers (Sysmex UF-5000, Siemens CLINITEK), confirm that the collection tube format and cap design are compatible with tube-handling robotics. Copan UriSponge&reg; (FDA-cleared October 2024) is a boric-acid-free device validated for direct loading on WASP&reg; automation systems. 
&nbsp;
<h2 dir="ltr">Specifications Context</h2>
 Standard urine collection cups are manufactured from transparent polypropylene (PP) or polystyrene (PS) with wide-mouth, screw-cap lids. Sterile cups rated for culture meet ISO 7886 and are non-pyrogenic. Boric acid preservative tubes contain approximately 1.8% boric acid, stabilizing bacterial counts by creating a bacteriostatic environment. Norgen urine preservative tubes (5&ndash;50 mL, available in multiple sizes) stabilize DNA, RNA, microRNA, and protein from fresh urine for over 2 years at room temperature per manufacturer validation data. As of 2026, liquid biopsy studies using urine cfDNA routinely use Streck Cell-Free DNA Urine Preservative (3 mL per 30 mL urine) as the standard stabilization protocol in published clinical research protocols.

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.

Transfer Pipettes

<h2>What are disposable transfer pipettes?</h2>
&nbsp;
Disposable transfer pipettes are single-use plastic liquid-handling tools made from low-density polyethylene (LDPE). They are designed as a one-piece bulb-and-stem system used for transferring, dispensing, and handling small volumes of liquids in laboratory workflows.
They are commonly used as a safer and more convenient alternative to glass Pasteur pipettes. Being plastic and disposable, they eliminate the risk of breakage, reduce cross-contamination, and remove the need for separate rubber bulbs. The flexible bulb allows controlled aspiration and dispensing of reagents, samples, and solutions.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Graduated transfer pipettes &ndash; for approximate volume measurement and controlled dispensing</li>
<li>Non-graduated transfer pipettes &ndash; for simple liquid transfer without measurement markings</li>
<li>Fine-tip transfer pipettes &ndash; for small droplets and precise spot dispensing</li>
<li>Sterile transfer pipettes &ndash; for microbiology and contamination-sensitive workflows</li>
<li>Non-sterile transfer pipettes &ndash; for routine laboratory use</li>
<li>Disposable Pasteur pipettes &ndash; for general single-use liquid handling</li>
</ul>
&nbsp;
<h2>How to choose transfer pipettes</h2>
&nbsp;
Tip style Fine-tip pipettes are used for precise work such as microplate spotting and small-volume handling. Standard tips are suitable for general transfers, while wide-bore designs are better for viscous liquids or blood samples. Longer stems help access deep containers.
Capacity and volume handling Select pipettes based on typical working volumes. Smaller pipettes are suitable for low-volume transfers, while larger ones are used for routine sample handling. The effective draw volume depends on bulb capacity and usage technique.
Graduated vs non-graduated Graduated pipettes allow approximate volume estimation and are useful in clinical and diagnostic workflows. Non-graduated pipettes are intended for general dispensing where precise measurement is not required.
Sterility requirements Sterile pipettes are used in microbiology, cell culture, and clinical applications where contamination control is essential. Non-sterile versions are suitable for general laboratory and teaching use.
Length and accessibility Long pipettes are preferred for deep vessels such as flasks and bottles, while shorter designs are used for compact tubes and small workspaces.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Disposable LDPE transfer pipettes are widely used laboratory consumables for general-purpose liquid handling in research, clinical, and educational environments. They are available in sterile and non-sterile formats with multiple tip designs and capacities to support different workflows.
These pipettes remain a standard alternative to glass Pasteur pipettes due to their safety, low cost, and reduced contamination risk in routine laboratory applications.

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;
&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.

Biopsy Cassettes

<h2 data-section-id="1l9wr55" data-start="0" data-end="29">What Are Biopsy Cassettes?</h2>
&nbsp;
Biopsy cassettes are specialized histology cassettes manufactured from acetal polymer (POM) and designed with fine 1 mm square mesh openings instead of the wider slots used in standard tissue cassettes. These fine mesh openings securely retain small tissue specimens such as gastric endoscopic biopsies, prostate needle cores, liver biopsies, and skin punch biopsies that could otherwise be lost during tissue processor agitation, vacuum cycles, and reagent exchanges. Like standard tissue cassettes, biopsy cassettes function as the specimen container throughout processing, embedding, and long-term paraffin block storage. Multi-compartment designs allow multiple tissue cores from different anatomical sites to be processed together while maintaining specimen orientation and identification.
Use biopsy cassettes for specimens smaller than approximately 3 mm. The fine 1 mm mesh is the key feature that prevents specimen loss during processing.

</ul>
&nbsp;
<h2 data-section-id="1h918vw" data-start="992" data-end="1025">How to Choose Biopsy Cassettes</h2>
&nbsp;
Single vs. Multi-Compartment
Single-compartment biopsy cassettes are the standard choice for processing one specimen per paraffin block and are suitable for most diagnostic biopsy applications. Multi-compartment cassettes, including four-compartment and six-compartment formats, allow several biopsy cores from different anatomical locations to be processed in the same cassette while preserving their positional identity. These formats are commonly used for prostate biopsy series and other multi-site sampling procedures.
Mesh Opening Size
Standard biopsy cassettes feature 1 mm square mesh openings that provide an effective balance between specimen retention and reagent flow. For ultrafine tissue cores, dispersed cell pellets, or particularly delicate specimens, microbiopsy or biomesh cassettes with smaller openings ranging from approximately 0.38 mm to 0.6 mm may provide better specimen containment.
Lid Design and Printer Compatibility
Globe Scientific biopsy cassettes utilize an integral click-shut hinged lid that closes securely and can be reopened multiple times without compromising closure integrity. This design is particularly useful during grossing procedures where specimens may need to be inspected before processing. Writing surfaces are available in both 30&deg; and 35&deg; angles to ensure compatibility with Leica and Sakura cassette labeling systems.
Foam Biopsy Pads
Biopsy foam pads are commonly used when processing extremely small tissue fragments. These polyester urethane foam inserts help immobilize specimens within the cassette, maintaining proper orientation and preventing movement during tissue processing while still allowing efficient reagent penetration and drainage.
Compatibility with Base Molds
Biopsy cassettes share the standard histology cassette footprint of approximately 40 &times; 28 &times; 6 mm, allowing compatibility with standard stainless steel and disposable plastic embedding molds. Multi-compartment designs maintain the same external dimensions while providing internal specimen separation.
&nbsp;
<h2 data-section-id="1jl751w" data-start="4594" data-end="4619">Specifications Context</h2>
&nbsp;
Globe Scientific biopsy cassettes are manufactured from durable acetal polymer and feature 1 mm square mesh openings engineered to maximize specimen retention while allowing efficient reagent penetration. The fine mesh design provides a large total open surface area for fluid exchange despite the smaller individual openings. These cassettes are resistant to formalin, xylene, graded alcohols, and acidic decalcifying agents commonly used in histology laboratories. The standard footprint of approximately 40 &times; 28 &times; 6 mm ensures compatibility with Leica ASP, Sakura VIP, Thermo Shandon Excelsior, and most other automated tissue processors. Globe Scientific maintains ISO 9001:2015 certification, and lot-specific conformance documentation is available upon request through MBP.

Sample Vial

<h2>What are Blood Collection Tubes for Nucleic Acid Research?</h2>
&nbsp;
Blood collection tubes for nucleic acid research are evacuated tubes pre-filled with a lysis reagent or anticoagulant that preserve DNA and/or RNA from whole blood specimens collected by standard venipuncture. On blood draw, the lysis reagent immediately inactivates nucleases and preserves both genomic DNA and RNA&mdash;including transcriptomic expression profiles&mdash;from 3&ndash;6 mL of mammalian whole blood. They are used in gene expression analysis, next-generation sequencing, PCR-based molecular diagnostics, cell-free DNA (cfDNA) studies, and biobank archiving. Choose blood collection tubes specifically formulated for nucleic acid preservation when the sample cannot be processed within 2&ndash;4 hours of draw.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Vacuum blood collection tubes for standardized sample volumes</li>
<li>Capillary blood collection tubes for small-volume sampling</li>
<li>Pediatric and micro-collection tubes for difficult draws</li>
<li>Sterile single-use blood collection tubes for diagnostic safety</li>
<li>General-purpose clinical and laboratory blood sampling tubes</li>
</ul>
&nbsp;
<h2>How to Choose Blood Collection Tubes</h2>
&nbsp;
DNA vs RNA vs Dual Preservation
K2 EDTA tubes (lavender cap) prevent clotting and preserve cellular morphology for CBC and flow cytometry, but RNA degrades rapidly without additional stabilization. Blood RNA stabilization tubes preserve intracellular RNA expression profiles, while dual-preservation blood collection tubes stabilize both DNA and RNA simultaneously, enabling downstream molecular analysis from a single specimen.
Blood Volume Per Tube
Standard blood collection tubes typically hold 3 mL or 6 mL. Confirm the draw volume against your extraction kit's minimum input requirement. Many NGS and RT-PCR extraction kits require 1&ndash;3 mL of whole blood per reaction, making 3 mL tubes sufficient for many single downstream applications.
Processing Window
For immediate processing (within 2 hours), standard K2 EDTA tubes are generally suitable. For delayed processing or sample shipment, choose blood collection tubes specifically formulated to stabilize nucleic acids according to the manufacturer's validated storage conditions.
Anticoagulant Type
K2 EDTA is the preferred anticoagulant for most molecular biology applications, including PCR and NGS. K3 EDTA may be used in some automated laboratory systems. Heparin is a known PCR inhibitor and should generally be avoided for nucleic acid workflows. Citrate tubes are not typically used for nucleic acid preservation.
Regulatory Compliance
For clinical or regulatory-submission workflows, confirm whether the blood collection tube has the appropriate regulatory approval or clearance for your intended application. Research-use-only (RUO) products are not intended for diagnostic use unless specifically authorized.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Standard evacuated blood collection tubes are commonly manufactured from medical-grade PET or glass. K2 EDTA tubes should be gently inverted 8&ndash;10 times immediately after collection to ensure complete anticoagulant mixing. Nucleic acid preservation tubes are available for both immediate processing and stabilized transport, depending on the manufacturer. DNA and RNA yield varies with donor characteristics, collection volume, storage conditions, and the extraction method used.

Glass Culture Tubes

<h2 data-section-id="163ce0l" data-start="0" data-end="32">What Are Glass Culture Tubes?</h2>
&nbsp;
Glass culture tubes are cylindrical laboratory vessels used for the cultivation, storage, and handling of biological samples, microbial cultures, and liquid reagents. Available in rimless, stopper-compatible, and screw-cap configurations, these tubes are commonly manufactured from borosilicate glass that meets USP Type I and ASTM E438 Type I Class B specifications. Unlike disposable plastic alternatives, borosilicate glass culture tubes withstand repeated autoclaving, exposure to aggressive chemicals, and routine laboratory sterilization procedures. They remain the preferred choice for reusable microbiology, clinical, and research laboratory applications where durability and chemical resistance are essential.
Choose borosilicate glass culture tubes when your workflow requires sterilization, chemical resistance, or repeated reuse. Choose polystyrene culture tubes for economical, single-use laboratory applications.

<h2 data-section-id="8x2xgg" data-start="974" data-end="1010">How to Choose Glass Culture Tubes</h2>
&nbsp;
Material: Borosilicate vs. Polystyrene
Borosilicate glass culture tubes offer excellent thermal and chemical resistance, making them suitable for repeated autoclaving at 121&deg;C and exposure to most laboratory acids and bases. Their low extractable content minimizes contamination and pH changes during sensitive biological and chemical procedures. Polystyrene culture tubes provide excellent optical clarity and are commonly used for routine laboratory assays and serial dilutions, but they are intended for single-use applications and are not suitable for autoclaving.
&nbsp;
Size and Capacity
The most commonly used culture tube sizes are 16 &times; 75 mm with an approximate capacity of 8 mL and 16 &times; 100 mm with an approximate capacity of 12 mL. Smaller formats such as 12 &times; 75 mm and 13 &times; 100 mm are also available for specialized applications. Selection should be based on sample volume requirements, incubation conditions, and compatibility with existing laboratory racks and equipment.
&nbsp;
Rim Style and Cap Compatibility
Rimless culture tubes are designed for use with cotton plugs, foam stoppers, or push-in closures and are widely used in microbiology laboratories. Screw-cap culture tubes provide a more secure seal for specimen transport, long-term storage, and contamination-sensitive applications. Laboratories should verify tube dimensions and rack compatibility before purchasing.
&nbsp;
Quantity and Pack Format
Culture tubes are commonly supplied in bulk quantities ranging from 250 to 1,000 units per case. High-volume laboratories often purchase case quantities to support routine testing, culture preparation, and clinical workflows while simplifying inventory management and purchasing processes.

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.

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.

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.
