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.

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

Capillary Tubes

<h2 dir="ltr">What are Capillary Tubes? </h2>
 Capillary tubes for laboratory use are thin-walled, open-ended tubes&mdash;typically 75 mm long with an internal diameter of 1.1&ndash;1.2 mm&mdash;that collect microvolume blood samples (40&ndash;80 &micro;L) by capillary action from finger-stick or heel-stick punctures, directly from anticoagulated blood collection tubes, or from blood gas analyzers. They are the primary consumables for the micro-hematocrit (packed cell volume, PCV) determination: tubes are filled, sealed, centrifuged at 10,000&ndash;14,500 RPM for 5 minutes, and the ratio of packed red cells to total blood column is read against a hematocrit chart. Globe Scientific manufactures both soda lime glass and plastic (unbreakable) micro-hematocrit capillary tubes, as well as pre-calibrated borosilicate glass tubes for blood gas applications. Choose heparinized capillary tubes for direct finger-stick collection from untreated blood; choose plain (untreated) tubes when filling from an anticoagulated blood collection tube.

<h2 dir="ltr"> How to Choose Capillary Tubes</h2>
 Plain vs. Heparinized Plain capillary tubes (blue tip, Globe Scientific) are used when filling from a pre-anticoagulated specimen (EDTA or citrate blood collection tube). Heparinized tubes prevent clotting in samples collected directly from a skin puncture: ammonium heparin&ndash;coated tubes (green tip) and sodium heparin&ndash;coated tubes (red tip) are both available. The tip color is the universal identifier &mdash; confirm the coding convention with your supplier before ordering, as some manufacturers reverse the color assignments. Glass vs. Plastic Soda lime glass capillary tubes (Globe Scientific catalog 51602&ndash;51607) provide excellent capillary action, low surface adsorption, and superior optical clarity for reading the hematocrit column. Plastic capillary tubes (catalog 51620) eliminate the sharps hazard from glass breakage during centrifugation&mdash;a significant occupational safety consideration for high-volume clinical labs processing hundreds of hematocrit determinations daily. Both formats fit standard 75 mm hematocrit centrifuges. Pre-Calibrated (Blood Gas) Tubes Pre-calibrated borosilicate glass capillary tubes (Globe Scientific catalog 51628, I.D. 0.55 mm &plusmn; 0.03 mm) are precision-ground for blood gas and co-oximetry analyzers requiring specific internal volume tolerance. These differ from standard hematocrit tubes in inner diameter; using the wrong tube in a blood gas analyzer causes instrument error codes and inaccurate analyte results. Centrifuge Compatibility All 75 mm micro-hematocrit capillary tubes are compatible with standard hematocrit centrifuges rated for 10,000&ndash;14,500 RPM. Confirm your centrifuge head accepts the tube O.D. (1.5 mm &plusmn; 0.05 mm for Globe Scientific glass tubes) before ordering in bulk.
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific soda lime glass micro-hematocrit capillary tubes have an I.D. of 1.15 mm &plusmn; 0.05 mm, O.D. of 1.5 mm &plusmn; 0.05 mm, and a length of 75 mm &plusmn; 1 mm, with a fill volume of approximately 75 &micro;L. The standard centrifugation protocol is 10,000&ndash;14,500 RPM for 5 minutes in a dedicated hematocrit centrifuge. Normal hematocrit ranges: 38&ndash;50% for adult males, 35&ndash;47% for adult females; values outside this range, combined with elevated ESR and other CBC parameters, are used to evaluate anemia, polycythemia, and inflammatory conditions. As of 2026, Globe Scientific is an ISO 9001:2015&ndash;certified manufacturer and MBP-stocked supplier of both glass and plastic capillary tube formats.

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.

&nbsp;
Staining: Coplin Jars Coplin staining jars are vertical-slot containers that hold 5&ndash;10 slides facing outward, immersing them simultaneously in staining reagents &mdash; haematoxylin, eosin, Gram stains, silver stains, and alcohols. Glass Coplin jars are solvent-resistant for xylene and all laboratory alcohols; polypropylene versions are suitable for aqueous and mildly solvent-containing reagents but are not xylene-compatible. &nbsp; Transport: Slide Mailers Three mailer types address different transport needs. Flip-top plastic mailers are reusable for short-range intra-facility transport. Polypropylene mailers with red screw caps provide a leak-proof sealed closure for shipping biological specimens. Cardboard mailers offer a lower-cost option for non-biohazardous, short-distance lab-to-lab sharing. &nbsp; Bench Access: Slide Dispensers Slide dispensers hold up to 72 slides in a tilted stack, dispensing one slide at a time from the front with one-handed access. This prevents contamination from repeatedly handling the full slide stack and reduces breakage during high-volume staining sessions. &nbsp; Archiving: 20-Place File Holders and Cabinets Twenty-place slide file holders accommodate a single case's slides in a flat, portable format suitable for filing or transporting a patient case. Expandable slide storage cabinets provide modular drawer-based storage for collections that grow over time, holding 100&ndash;500+ slides per cabinet unit.

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 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.
&nbsp;
<h2 data-section-id="1jl751w" data-start="4384" data-end="4409">Specifications Context</h2>
&nbsp;
PPCO centrifuge bottles are manufactured from durable polypropylene copolymer materials that offer excellent chemical resistance, translucency for sample visibility, and compatibility with autoclave sterilization procedures. They are widely used with preparative centrifuge systems, including various fixed-angle and swing-bucket rotor configurations.

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.
