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;

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.

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.
MBP supports procurement departments by accepting purchase orders and offering institutional pricing for qualified high-volume customers. <a href="https://mbpinc.net/contact-us">Contact the MBP team today</a> for a customized quote.

<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

Innoculating Needles/Loops

<h2 data-section-id="y6ykl1" data-start="0" data-end="42">What Are Inoculating Loops and Needles?</h2>
&nbsp;
Inoculating loops and needles are essential microbiology tools used to transfer microorganisms between culture media, agar plates, broth tubes, and other laboratory growth systems. An inoculating loop features a small circular end designed to hold a defined volume of liquid culture, while an inoculating needle has a straight tip used for picking colonies and inoculating semi-solid media. Modern disposable versions are manufactured from sterile polypropylene or polystyrene and have largely replaced reusable metal loops in many laboratories, helping reduce cross-contamination risks and eliminating the need for flame sterilization between samples. These tools are widely used in clinical microbiology, research laboratories, pharmaceutical testing, food microbiology, and environmental monitoring applications.

<h2 data-section-id="x4zq8w" data-start="861" data-end="907">How to Choose Inoculating Loops and Needles</h2>
&nbsp;
Volume: 1 &micro;L vs. 10 &micro;L
The choice of loop volume depends on the application. A 1 &micro;L calibrated loop is commonly used for quantitative urine cultures and other procedures where accurate sample volume directly affects colony counts and microbial enumeration. A 10 &micro;L loop is the standard option for routine streak plating, subculturing, and general microorganism transfer where larger sample volumes are beneficial.
Rigidity: Flexible PP vs. Rigid PS
Flexible polypropylene loops are designed to glide smoothly across agar surfaces, minimizing damage to the media during streaking procedures. Rigid polystyrene loops and needles provide greater control when inoculating broth cultures, retrieving colonies, or performing stab inoculations in semi-solid agar. Many laboratories keep both flexible and rigid options available to accommodate different microbiological techniques.
Calibration and Lot Certification
For quantitative microbiology applications, calibrated loops should be selected to ensure consistent volume delivery. Certified loops undergo validation testing to verify that they deliver the specified sample volume accurately. This level of quality assurance is particularly important in clinical laboratories performing urine cultures and other quantitative microbial analyses.
Packaging Format
Individually packaged sterile loops provide maximum sterility assurance and are ideal for low-volume testing environments. Bulk-packaged sterile loops offer a more economical solution for high-throughput laboratories where large quantities are used daily. The choice depends on workflow requirements, usage frequency, and laboratory contamination-control practices.
&nbsp;
<h2 data-section-id="1jl751w" data-start="3179" data-end="3204">Specifications Context</h2>
&nbsp;
Disposable inoculating loops and needles are typically manufactured from medical-grade polypropylene or polystyrene and supplied sterile for immediate use.

<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).

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.

&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.

Biohazard Bags

<h2 dir="ltr">What are Biohazard Bags?</h2>
 Biohazard bags are polyethylene pouches printed with the universal biohazard symbol and standardized warning text, used to contain, transport, and dispose of biological specimens and infectious waste in clinical, diagnostic, and research laboratory settings. They are manufactured in two functionally distinct categories: specimen transport bags (thin-walled LDPE, zipper-closure, with document pouch) for routing patient specimens from collection point to laboratory; and autoclave/waste bags (heavy-gauge polypropylene, heat-sealable) for containing infectious solid waste before steam sterilization at 121&ndash;136 &deg;C. Choose a specimen transport bag for courier or inter-department specimen routing; choose an autoclave bag for infectious solid waste destined for steam sterilization.

<h2 dir="ltr"> How to Choose Biohazard Bags</h2>
 Specimen Transport vs. Waste/Autoclave Function Specimen transport bags (Globe Scientific catalog 4923&ndash;4950) are LDPE, zipper-locked, with a separate document pouch for the requisition form and a tear zone for rapid opening at the receiving lab. They are not rated for autoclaving. Autoclave bags (PP, 0.05 mm, 12&times;26 in. or 24&times;32 in.) withstand 121&ndash;136 &deg;C sterilization cycles and comply with OSHA 29 CFR 1910.1030 markings for biohazardous waste disposal. Size Selection for Specimen Transport Globe Scientific offers 6&times;9 in. (for blood tubes, urine cups, small specimens), 8&times;10 in. (for multiple tubes or swab collections), and 12&times;15 in. (for large containers, pathology specimens). The 6&times;9 in. bag with absorbent pad (catalog 4924) is the most common format for clinical specimen routing; the pad absorbs up to 10 mL of liquid in the event of tube breakage. Absorbent Pad Requirement IATA Dangerous Goods Regulations and the UN3373 Biological Substance Category B shipping requirements mandate an absorbent material sufficient to absorb the total liquid volume of the primary container. The 6&times;9 in. with absorbent pad format meets this requirement for standard tube shipments. Confirm pad absorbency against your primary container volume before use in P650 mailing kits. STAT vs. Standard Globe Scientific STAT bags (catalog 4950) are red-tinted 6&times;9 in. bags with a document pouch and tear zone &mdash; the red color alerts laboratory staff to prioritize the specimen. Use STAT bags for critical or time-sensitive specimens that bypass standard routing. Closure Type Zipper-closure bags allow repeated access and are used where the specimen may need to be resealed for courier transit. Glue-closure (tamper-evident seal) bags prevent re-opening and are preferred for chain-of-custody specimens (forensics, drug testing) and any application where tamper evidence is required.
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific specimen transport bags are manufactured from LDPE with a printed biohazard symbol and special handling checkboxes. The 6&times;9 in. standard format (catalog 4923) and STAT format (4950) hold cases of 1,000 bags (100/pack &times; 10 packs). The 8&times;10 in. (4926) and 12&times;15 in. (4929) formats are cases of 1,000 and 500, respectively. Autoclave bags used for infectious solid waste must comply with OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), which requires fluorescent orange or orange-red color-coding or a biohazard symbol on all containers holding regulated waste. Globe Scientific biohazard bags are manufactured under ISO 9001:2015 quality management standards. Bags are non-sterile; sterile transport systems for specimens requiring sterility assurance should use appropriately certified collection vessels inside the bag.

Plastic Beakers

<h2 data-section-id="174q2lb" data-start="139" data-end="167">What Are Plastic Beakers?</h2>
&nbsp;
Plastic beakers are shatterproof cylindrical laboratory vessels manufactured from polypropylene (PP) or polymethylpentene (PMP), designed for safe and lightweight liquid handling in environments where glass breakage is a concern. Polypropylene (PP) is the most commonly used material due to its strong chemical resistance to dilute acids, bases, alcohols, and most aqueous reagents, along with autoclavability at 121&deg;C and permanently molded graduations that do not fade with use. Polymethylpentene (PMP) offers higher optical clarity and better heat tolerance, making it suitable for applications requiring visual monitoring of solutions. Choose PP plastic beakers for routine buffer preparation, aqueous reagents, teaching labs, and field use; choose glass beakers when working with organic solvents, high temperatures above ~135&deg;C, or when maximum optical clarity is required.

<h2 data-section-id="149sszu" data-start="1054" data-end="1086">How to Choose Plastic Beakers</h2>
&nbsp;
Material: Polypropylene vs. Polymethylpentene
Polypropylene (PP) beakers are the standard choice in most laboratories because they are autoclavable at 121&deg;C, cost-effective, and resistant to a wide range of aqueous reagents including dilute acids and bases. They are typically translucent and designed for general-purpose laboratory workflows. Polymethylpentene (PMP) beakers, on the other hand, offer near-glass optical clarity (approximately 90% light transmission) and can tolerate higher temperatures up to around 175&deg;C, making them suitable for applications where visibility of the solution is important during mixing or heating.
Graduation Type: Molded-In
Plastic beakers at MBP feature molded-in graduations that are permanently embossed into the wall of the vessel. These markings remain legible even after repeated autoclaving, chemical exposure, and washing cycles, making them more durable than printed alternatives and ideal for long-term reuse.
Volume Range
MBP supplies plastic beakers in sizes ranging from 5 mL to 10,000 mL. Small-volume beakers (5&ndash;50 mL) are used for micro-scale reagent preparation, while mid-range sizes (250 mL&ndash;1,000 mL) are standard for routine buffer preparation. Large-capacity beakers (2,000&ndash;10,000 mL) are used for bulk reagent mixing, media preparation, and large-scale laboratory workflows.
Tri-Corner Beaker Option
Tri-corner (tri-pour) beakers are a specialized plastic format designed with three pour spouts for controlled dispensing and reduced dripping. These are commonly used in reagent distribution stations, waste handling, and workflows requiring frequent liquid transfer. They are typically made from polypropylene and complement standard round-form beakers.
&nbsp;
<h2 data-section-id="1jl751w" data-start="3281" data-end="3306">Specifications Context</h2>
&nbsp;
Polypropylene (PP) has a density of approximately 0.91 g/cm&sup3; and is chemically resistant to dilute acids (HCl, H₂SO₄), bases (NaOH, KOH), alcohols, and most aqueous buffers. However, it is not compatible with concentrated oxidizing acids (such as concentrated nitric or sulfuric acid) or halogenated organic solvents (such as chloroform, methylene chloride, or xylene). Molded graduations typically maintain an accuracy of &plusmn;5% of total capacity. PMP provides higher transparency and improved heat resistance compared to PP but is generally more expensive.
MBP stocks plastic beakers in a full range of sizes from 5 mL to 10,000 mL, including standard round-form and tri-corner designs for institutional laboratory use.

Freezer Boxes

<h2 data-section-id="1k6bkqk" data-start="294" data-end="320">What Are Freezer Boxes?</h2>
&nbsp;
Freezer boxes are lidded storage containers with a numbered grid of individual wells designed to organize cryogenic vials, microcentrifuge tubes, and centrifuge tubes in ultra-low temperature (ULT) freezers, liquid nitrogen dewars, and vapor-phase cryogenic storage systems. Standard formats include 2-inch (51 mm) and 3-inch (76 mm) box heights, with common well configurations of 25-place (5&times;5), 81-place (9&times;9), and 100-place (10&times;10).
The 81-well, 2-inch freezer box is one of the most commonly used formats for storing 1.8&ndash;2.0 mL cryogenic vials in biobanking, pharmaceutical, and research laboratories. Cardboard and hard-wall freezer boxes are both suitable for ultra-low temperature storage, while polycarbonate and polypropylene boxes are preferred for applications requiring repeated handling and autoclaving.

<h2 data-section-id="unvo09" data-start="1142" data-end="1172">How to Choose Freezer Boxes</h2>
&nbsp;
Material: Cardboard vs. Polycarbonate vs. Polypropylene
Cardboard freezer boxes with water-resistant coatings provide an economical solution for long-term storage in &minus;80&deg;C freezers and vapor-phase liquid nitrogen environments. These boxes are lightweight and disposable but are not autoclavable.
Polycarbonate (PC) freezer boxes feature transparent lids that allow sample identification without opening the box and can withstand autoclaving at 121&deg;C. Polypropylene (PP) freezer boxes also support autoclaving and offer enhanced chemical resistance. For frequently accessed sample collections, PC and PP boxes provide greater durability than cardboard alternatives.
Well Count: 81-Well vs. 100-Well
An 81-well (9&times;9) freezer box is typically designed for cryogenic vials up to approximately 13 mm outer diameter, making it suitable for most 1.8&ndash;2.0 mL cryovials.
A 100-well (10&times;10) freezer box accommodates smaller tubes up to approximately 12 mm outer diameter, including many 1.2&ndash;1.5 mL cryovials and standard microcentrifuge tubes, maximizing storage density within the same footprint.
Box Height: 2-Inch vs. 3-Inch
2-inch freezer boxes are commonly used for cryogenic vials up to 2 mL. Larger 3-inch boxes are designed for higher-capacity sample tubes, including 3&ndash;5 mL cryovials and selected centrifuge tube formats. When using mixed box heights within freezer racks or drawers, verify rack compatibility before purchasing.
Temperature Rating and Liquid Nitrogen Compatibility
Freezer boxes are available for storage temperatures as low as &minus;196&deg;C. Hard-wall polycarbonate and polypropylene boxes are generally preferred for demanding cryogenic applications and repeated handling. Cardboard freezer boxes are commonly used in vapor-phase liquid nitrogen storage and ultra-low temperature freezers.
&nbsp;

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.

<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.
