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.

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.

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.

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.

<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="1k6o3gy" data-start="0" data-end="50">What Are Midicentrifuge Tubes (5 mL and 10 mL)?</h2>
&nbsp;
Midicentrifuge tubes are polypropylene conical tubes available in 5 mL and 10 mL capacities, designed for laboratory workflows that require sample volumes larger than standard microtubes but smaller than traditional 15 mL conical tubes. These tubes provide an efficient solution for intermediate-volume applications and are commonly used in cell culture, protein purification, gradient fraction collection, virus concentration, and clinical specimen processing.
By filling the gap between 2 mL microcentrifuge tubes and 15 mL conical tubes, midi tubes help optimize sample handling and centrifugation efficiency while reducing unnecessary tube volume and excess headspace.
Midicentrifuge tubes are ideal for sample volumes between approximately 2 mL and 12 mL, especially when a 15 mL conical tube is too large for the application or incompatible with the available rotor setup.

&nbsp;
Selecting the Appropriate Volume
The choice between 5 mL and 10 mL tubes depends on the volume of your samples and workflow requirements.
5 mL midi tubes are well suited for applications involving smaller sample volumes, typically below 4.5 mL. They minimize excess headspace and can improve pellet formation during lower-speed centrifugation procedures.
10 mL midi tubes are commonly used for larger intermediate-volume applications, including culture supernatant collection, protein purification workflows, and virus concentration protocols requiring volumes between 6 mL and 10 mL.
Rotor Compatibility
Before purchasing midi tubes, verify that your centrifuge rotor or adapter system is designed to accommodate 5 mL or 10 mL formats. While many benchtop centrifuges support these tubes through dedicated adapters, compatibility varies by manufacturer and rotor model.
The standard dimensions of Globe Scientific 10 mL centrifuge tubes are compatible with many commonly used conical tube adapters found in research and clinical laboratories.
Sterility and Cap Design
Sterile midi tubes with attached screw caps are recommended for cell culture, clinical specimens, and applications where contamination control is essential. Attached caps also reduce the risk of sample mix-ups and accidental contamination.
Non-sterile tubes with separate caps may offer a more economical option for routine laboratory procedures where sterility is not required.
Packaging Considerations
Most midi tubes are supplied in bagged packaging rather than racks. A common configuration includes 100 tubes per bag, making them suitable for laboratories that process moderate to high sample volumes. Reviewing expected usage rates can help determine appropriate ordering quantities and inventory levels.

Transport Tubes

<h2 dir="ltr">What are Transport Tubes?</h2>
 Transport tubes are sterile, leak-proof screw-cap tubes used for collecting, transporting, and temporarily storing biological specimens from the collection site to the testing laboratory. They span a broad category: empty specimen containers (15 mL and 50 mL self-standing conical tubes), pre-filled saline transport tubes, UTM (Universal Transport Medium) tubes, and specialty specimen vials. All transport tubes share three required attributes&mdash;leak-proof construction, sterility confirmation, and compatibility with the downstream assay's matrix requirements. Choose the transport tube type based on the specimen, the target analyte, and the assay platform it will be processed on.

<h2 dir="ltr">How to Choose Transport Tubes</h2>
 Material: Polypropylene (PP) vs. Polystyrene (PS) PP conical transport tubes are chemical-resistant, autoclavable, and certified DNase/RNase-free in molecular-grade formats. PS transport tubes (30 mL translucent format, Globe Scientific) are lighter and less expensive but not autoclavable. For nucleic acid work, DNA/RNA-free certified PP is the standard. For specimen transport requiring centrifugation, PP is preferred due to higher g-force tolerance (PP rated to &ge;10,000 &times; g in most formats). Self-Standing vs. Rack Format Self-standing (skirted-base) conical tubes stand upright without a rack, reducing knock-over risk during aliquoting and transport. Rack-based tubes require a separate holder. Globe Scientific self-standing 50 mL PP transport tubes feature a printed graduation, white frosted writing area, and are available sterile, non-sterile, or metal-free. Sterile tubes are RNase/DNase-free and pyrogen-free per the lot certificate. Sterile vs. Non-Sterile Sterile tubes (ISO 11137 radiation sterilization, SAL 10⁻⁶) are required for culture, NAAT, and any specimen where contamination would invalidate the result. Non-sterile metal-free PP tubes are suited to trace-element analysis and environmental sampling where sterility is not required but metal contamination would interfere. Volume 15 mL tubes are standard for most clinical specimen aliquots, urine transfers, and culture setups. 50 mL tubes are used for higher-volume specimens (24-hour urine aliquots, stool homogenates, bulk transport of tissue homogenates). Globe Scientific 30 mL tubes with integral spoon are designed specifically for fecal specimen self-collection. Media and Additives Empty transport tubes (no fill) are the base format; select a pre-filled tube (saline, UTM, boric acid) based on the specimen type and analyte stability requirements. For nucleic acid targets, pre-filled tubes with DNA/RNA Shield, UTM, or saline are the appropriate formats. 
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific self-standing 50 mL conical transport tubes are manufactured from USP Class VI medical-grade PP with a conical bottom skirt for freestanding stability. Printed graduation marks (1 mL intervals) and a frosted writing area are standard features. Sterile versions are individually wrapped and certified RNase-free, DNase-free, and pyrogen-free per lot certificate, consistent with ISO 9001:2015 manufacturing standards. Non-sterile metal-free versions are supplied with a separate natural screw cap and are tested for trace metals via ICP-MS before lot release. MBP's transport tubes catalog includes Globe Scientific and NEST Scientific formats in multiple pack sizes (25/bag and bulk packs of 500).

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. MBP supplies Globe Scientific and NEST Scientific test tube lines for research and clinical labs across the USA, Canada, and worldwide. &nbsp;
