Tubes & Sample Collection

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;

Sample Storage Container

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

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

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.

&nbsp;
<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
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.

Vacuum Bottles

<h2 data-section-id="1vcmyco" data-start="0" data-end="27">What Are Vacuum Bottles?</h2>
&nbsp;
Laboratory vacuum bottles are specialized receiver containers designed to withstand vacuum pressure during filtration workflows. They serve as the collection vessel in vacuum filtration systems, capturing filtered solutions immediately after they pass through a membrane filter. Vacuum bottles are commonly used for sterile filtration of cell culture media, biological buffers, aqueous reagents, protein solutions, and other heat-sensitive liquids that cannot be sterilized by autoclaving. They are also widely used as waste collection bottles in cell culture aspiration systems, where vacuum pressure removes spent media and wash solutions from culture vessels.
Unlike standard storage bottles, vacuum bottles are specifically engineered to maintain structural integrity under negative pressure without collapsing, deforming, or leaking during filtration.

<h2 data-section-id="16tksnx" data-start="1015" data-end="1046">How to Choose Vacuum Bottles</h2>
&nbsp;
Membrane Type and Pore Size
When selecting a vacuum filtration system, membrane choice is often the most important factor. Polyethersulfone (PES) membranes provide high flow rates and low protein binding, making them the preferred option for cell culture media, buffers, and most biological solutions. Polyvinylidene fluoride (PVDF) membranes offer broader chemical compatibility and are often selected for solutions containing detergents or certain organic compounds.
For sterile filtration, a 0.22 &micro;m membrane is the standard choice because it effectively removes bacteria and other contaminants. A 0.45 &micro;m membrane is generally used for clarification, particulate removal, and HPLC mobile phase preparation rather than sterile applications.
System Volume
Vacuum filtration systems are commonly available in capacities ranging from 150 mL to 1000 mL. Smaller volumes are suitable for routine laboratory preparations, while 500 mL and 1000 mL systems are widely used for larger batches of media and buffer preparation. Matching bottle size to the expected filtration volume helps maximize efficiency and minimize handling steps.
Receiver Bottle Material
Polystyrene (PS) receiver bottles are commonly supplied with complete single-use vacuum filtration systems because they provide excellent clarity for monitoring liquid levels during filtration. PETG receiver bottles offer enhanced durability and broader temperature compatibility, making them suitable when filtered solutions may be stored at refrigerated or freezer temperatures after filtration.
Sterility Requirements
Most complete vacuum filtration systems are supplied sterile and individually packaged for immediate use. When purchasing replacement receiver bottles separately, laboratories should verify sterility specifications if the bottles will be used for sterile media or reagent storage after filtration.
Thread Compatibility
Many vacuum filtration systems utilize standardized GL45 threaded connections that allow compatibility between filtration funnels, receiver bottles, and related accessories. Confirming thread compatibility is important when combining components from different product lines or manufacturers.

&nbsp;
Modern vacuum filtration systems are typically supplied with PES or PVDF membrane options and are available in configurations ranging from 150 mL to 1000 mL. Many systems utilize GL45-threaded receiver bottles that integrate with standard laboratory filtration accessories and media bottle systems. Angled hose-barb vacuum connectors have become standard across most product lines because they accommodate a wide range of vacuum tubing sizes without requiring additional adapters. As of 2026, vacuum filtration remains the preferred method for sterile preparation of heat-sensitive biological solutions in research, pharmaceutical, biotechnology, and clinical laboratories.

Wash Bottles

<h2 data-section-id="gy6c1g" data-start="0" data-end="42">What Are Laboratory Wash Mouth Bottles?</h2>
&nbsp;
Laboratory wash bottles, also known as squeeze bottles or wash mouth bottles, are flexible LDPE containers available in 250 mL, 500 mL, and 1000 mL capacities. They feature a narrow dispensing nozzle or integrated draw-tube spout that delivers a controlled stream of liquid when the bottle is squeezed by hand. The flexibility of LDPE enables this dispensing action, making it the preferred material for wash bottles. These bottles are commonly used for rinsing laboratory glassware with distilled or deionized water, dispensing solvents during sample preparation, flushing residues during titrations and extractions, and directing liquids into narrow-neck vessels. Globe Scientific wash bottles are available with color-coded polypropylene caps and GHS-labeled safety-vented options for handling volatile solvents. Safety-vented wash bottles should always be used with volatile solvents such as ethanol, methanol, isopropanol, and acetone to prevent pressure build-up caused by vapor expansion.

&nbsp;
Vented vs. Non-Vented
Non-vented wash bottles are suitable for deionized water, distilled water, and other non-volatile aqueous solutions. Safety-vented wash bottles include a pressure-relief vent in the dispensing nozzle, allowing solvent vapors to escape safely and reducing the risk of pressure accumulation. These bottles are recommended for volatile solvents such as ethanol, methanol, isopropanol, and acetone. Globe Scientific GHS-labeled wash bottles combine safety venting with pre-printed hazard labeling for improved chemical identification and compliance.
Color-Coded Cap System
Color-coded caps help prevent reagent mix-ups in busy laboratory environments. A commonly used convention is blue for water, red for ethanol, yellow for isopropanol, green for methanol, and white for custom labeling or general use. Establishing a consistent color-coding system throughout the laboratory helps improve safety and workflow efficiency.
Wide Mouth vs. Standard Design
Standard wash bottles use a narrow draw tube extending to the base of the bottle, allowing liquid dispensing while the bottle remains upright. Wide-mouth wash bottles feature a larger neck opening, making refilling from bulk containers, carboys, or reagent bottles faster and easier. Laboratories that refill bottles frequently often prefer wide-mouth designs to reduce spills and simplify handling.
Volume Selection
The 500 mL wash bottle is the most common laboratory size, providing a balance between capacity and ease of handling. A 250 mL bottle is ideal when smaller volumes are sufficient or greater dispensing control is required. For high-throughput environments where liquids are used continuously, 1000 mL bottles minimize refill frequency and improve efficiency.
