Glass Culture Tubes

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

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

Compatible with cotton plugs and laboratory stoppers, they are commonly used in microbiology, cell culture, and general laboratory procedures where durability and autoclave compatibility are required.
&nbsp;
Borosilicate Screw-Cap Culture Tubes Featuring threaded closures for secure sealing, these tubes are ideal for specimen transport, reagent preparation, and long-term incubation studies. The screw-cap design minimizes contamination risk and reduces evaporation during storage.
&nbsp;
Polystyrene (PS) Culture Tubes Polystyrene tubes provide excellent optical clarity and are intended for single-use laboratory applications such as serial dilutions, colorimetric assays, and ELISA preparation workflows. They offer a lower cost per tube compared with reusable glass alternatives.
&nbsp;
16 &times; 75 mm (Approximately 8 mL) Culture Tubes This compact format is commonly selected for low-volume cultures, blood culture screening, serial dilution procedures, and routine laboratory testing where smaller sample volumes are sufficient.
&nbsp;
16 &times; 100 mm (Approximately 12 mL) Culture Tubes The larger 12 mL format provides additional working volume for microbial enrichment broths, larger reaction mixtures, and culture applications requiring increased sample capacity.

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.

 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.

Thermal Labels

<h2 dir="ltr">What Are Laboratory Thermal Labels?</h2>
 Laboratory thermal labels are adhesive labels designed for printing by direct-thermal or thermal-transfer desktop label printers &mdash; the two print technologies used for barcode and specimen ID generation in research, clinical, and diagnostic labs. Direct-thermal labels activate a heat-sensitive coating to produce an image without ink or ribbon; thermal-transfer labels use a resin or wax ribbon to fuse ink into the label surface. Thermal labels cover a wide range of container types: cryo vials, microcentrifuge tubes, PCR strips, 15/50 mL conicals, microscope slides, and specimen collection bags. Choose thermal-transfer labels for any sample requiring chemical resistance, temperatures above +50 &deg;C, or long-term barcode legibility; choose direct-thermal for low-cost, short-to-medium-term applications.

 Print Technology Compatibility Confirm whether the printer is direct-thermal (no ribbon required, e.g., Zebra GK420d, DYMO LabelWriter) or thermal-transfer (ribbon required, e.g., Zebra ZT230, Datamax M-Class). The two label types are not interchangeable &mdash; a thermal-transfer label will not print correctly in a direct-thermal printer and vice versa. Temperature and Chemical Exposure Direct-thermal label coatings degrade above approximately 50&ndash;60 &deg;C and with prolonged UV exposure, limiting their use to room-temperature and short-term cold storage applications. Thermal-transfer labels with a resin ribbon produce output resistant to temperatures up to +100 &deg;C, ethanol, xylene, and sanitizing wipes &mdash; required for autoclave tracking, histology, and GLP-regulated sample management. Container and Size Match Label dimensions must match the printable area of the label and the geometry of the container. Common lab thermal label widths are 0.5&ndash;2 inches; lengths are 0.25&ndash;3 inches. Verify dimensions against the container's flat-printable surface, accounting for any wrap-around on curved vials. Roll Core and Printer Compatibility Standard roll cores are 1-inch inner diameter for compact desktop printers; 3-inch cores fit high-volume industrial label printers. Confirm the printer's maximum roll diameter and label width capability before selecting roll format. Material: Paper vs. Polyester Paper-based thermal labels cost less and are suitable for ambient-temperature, short-duration applications (reagent dating, sample intake). Polyester thermal labels are moisture-resistant, more tear-resistant, and rated for demanding environments including freezers and chemical splash &mdash; specified for long-term specimen tracking and any application where label durability is a safety or compliance requirement. 
<h2 dir="ltr"> Specifications Context</h2>
 Direct-thermal label paper weight is typically 58&ndash;80 g/m&sup2;; polyester variants are 50&ndash;100 &micro;m thick. Standard roll dimensions are 2.25 inches &times; 1.25 inches (common for specimen tubes) and 4 inches &times; 6 inches (common for shipping and larger specimen bags). Print resolution for lab barcode labels should be 300 dpi for 1D/2D barcodes on labels smaller than 1 inch &times; 0.5 inch &mdash; 203 dpi produces legible output on larger-format labels.&nbsp;

Vacuum Filtration

<h2 dir="ltr">What are Vacuum Bottle-Top Filter Systems?</h2>
 Vacuum bottle-top filter systems are single-use, sterile filtration assemblies consisting of a graduated polystyrene funnel with an integrated membrane filter bonded to a polystyrene receiver bottle, connected by a hose-port adaptor to a house vacuum line or benchtop vacuum pump. The applied negative pressure (&minus;50 to &minus;100 kPa) draws liquid through the membrane into the receiver bottle, which is sealed after filtration for immediate use or cold-room storage.&nbsp;

<h2 dir="ltr"> How to Choose Vacuum Filtration Systems</h2>
 PES vs. PVDF Membrane for Vacuum Filtration PES membranes provide low protein binding (~1&ndash;2 &micro;g/cm&sup2;), high flow rates, and broad aqueous-solution compatibility &mdash; the standard for routine DMEM, RPMI, HBSS, PBS, and supplement-containing media sterilization. PVDF membranes have slightly lower protein binding than PES and greater chemical resistance to mild organic solvents, mild acids, and alkaline solutions. Use PVDF when filtering protein-rich solutions (FBS, antibody preparations, conditioned medium with high protein content) or when mild organic solvents are present in the filter solution. Volume Selection 250 mL systems (50 mm diameter membrane, 50 mL funnel) suit small media aliquots, supplement solutions, and transfection reagent preparations. 500 mL systems (90 mm diameter membrane, 150 mL funnel) are the routine lab workhorse for standard 500 mL media bottle preparation and FBS filtration. 1,000 mL systems (90 mm diameter membrane, 350 mL funnel) handle full-liter media preparations and large-volume buffer sterilization. All NEST systems include a pre-attached, graduated polystyrene receiver bottle in the corresponding volume. Pore Size: 0.10 &micro;m vs. 0.22 &micro;m vs. 0.45 &micro;m 0.22 &micro;m is the sterilizing grade per USP &lt;1229.2&gt; and ICH Q9: retains all bacteria and fungi; used for routine cell culture media, PBS, and buffer preparation. 0.45 &micro;m is the clarification grade: used as a pre-filtration step before 0.22 &micro;m to remove large particulates from turbid or high-biomass samples (FBS, conditioned media, cell culture supernatants, crude lysates), extending 0.22 &micro;m filter throughput by 3&ndash;5&times; on difficult samples. 0.10 &micro;m is the mycoplasma-removal grade: required when preparing media for Mycoplasma-sensitive primary cell culture or when processing serum or supplementary reagents that may harbor Mycoplasma species. Note that 0.10 &micro;m filtration is substantially slower than 0.22 &micro;m due to the tighter membrane pore structure. Practical Tips for Maximum Throughput Pre-wet the membrane by briefly passing 5&ndash;10 mL of sterile water through before the sample &mdash; this wets the hydrophilic PES or PVDF membrane and reduces initial resistance. For FBS and other viscous solutions, pre-filter through 0.45 &micro;m before the 0.22 &micro;m step. Maintain a vacuum at &minus;50 to &minus;80 kPa; excessive vacuum (&gt; &minus;100 kPa) can shear fragile membrane pores and increase non-specific protein adsorption. Do not autoclave the assembled bottle-top filter &mdash; PES and PS components are not rated for autoclave sterilization. 
<h2 dir="ltr"> Specifications Context</h2>
 NEST Scientific vacuum bottle-top filters are manufactured from polystyrene funnel and receiver bottle components with PES or PVDF membranes.

Tissue Cassettes

<h2 data-section-id="12g32xm" data-start="194" data-end="223">What Are Tissue Cassettes?</h2>
&nbsp;
Tissue cassettes are rectangular acetal polymer (POM) containers used in surgical pathology and research histology to carry gross tissue specimens&mdash;including resections, excisions, and large biopsy cores&mdash;from the grossing table through the complete paraffin processing workflow. Wide-slot perforations (approximately 1.5 mm) allow rapid reagent penetration and drainage during automated tissue processor cycles while preventing specimen loss for samples measuring 3 mm or larger in their smallest dimension. Following processing, the cassette base fits directly into a metal or disposable plastic base mold for paraffin embedding, and the completed paraffin block is archived with the cassette serving as the primary specimen identifier.
Standard tissue cassettes handle the majority of surgical pathology specimens; use biopsy cassettes for specimens smaller than approximately 3 mm.

&nbsp;
Writing Area Angle: 30&deg; vs. 35&deg;
Globe Scientific tissue cassettes are available with 30&deg; and 35&deg; angled writing surfaces to match Leica and Sakura cassette printer platen angles. Selecting the incorrect angle can create printing alignment issues and slow workflow efficiency. Laboratories should verify printer specifications before ordering case quantities.
Integral Lid vs. Separate Lid
Integral hinged-lid tissue cassettes snap closed without requiring a separate steel lid, reducing handling steps in high-volume grossing environments. Separate-lid cassettes are compatible with standard metal base molds and are often preferred in embedding stations where lids must be removed independently. Both formats are compatible with standard tissue processor baskets.
Color Coding
Globe Scientific offers tissue cassettes in more than ten standard colors. Many laboratories assign colors by specimen type or department to improve organization and reduce the risk of specimen identification errors during high-volume processing.
Pack Format: Standard Box vs. QuickLoad Sleeves
Standard 500-count dispenser boxes meet the needs of most laboratories. QuickLoad&reg; and E-Z Load&reg; sleeve formats provide pre-counted cassette stacks for rapid one-handed dispensing and are particularly useful in grossing stations processing more than 300 specimens per day.
Compatibility with Tissue Processors
The standard 40 &times; 28 &times; 6 mm cassette footprint is compatible with Leica ASP, Sakura VIP, Thermo Shandon Excelsior, and most other automated tissue processors without modification. Compatibility should be verified when ordering Mega or deep-body cassette variants.

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.

<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.

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.
