Tubes & Sample Collection

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.

Cuvettes

<h2 dir="ltr">What are Cuvettes?</h2>
 Cuvettes are small, precision-dimensioned transparent vessels used to hold liquid samples in the light path of a spectrophotometer, fluorometer, or colorimeter for measurement of absorbance, transmittance, fluorescence intensity, or fluorescence polarization. The standard cuvette has a 10 mm optical path length (the distance light travels through the sample), a square or rectangular cross-section, and an internal volume of 1&ndash;4 mL. Cuvettes are manufactured in four main materials&mdash;polystyrene (PS) or polymethylmethacrylate (PMMA) plastic, optical glass, UV-grade quartz (fused silica), and IR quartz&mdash;each covering a different wavelength range. Choose plastic cuvettes for routine visible-light absorbance (380&ndash;780 nm) where disposability prevents cross-contamination; choose optical glass for reusable visible-range work (340&ndash;2,500 nm); choose UV quartz when measurements extend into the UV range below 340 nm (190&ndash;2,500 nm).

<h2 dir="ltr"> How to Choose Cuvettes</h2>
 Material and Wavelength Range Plastic (PS/PMMA) cuvettes transmit visible light from 380&ndash;780 nm and are single-use, eliminating cleaning and cross-contamination risk. They are unsuitable for UV measurements, organic solvents, or strong acids. Optical glass cuvettes transmit 340&ndash;2,500 nm, covering the full visible and near-infrared range; Different manufacturers recommend different procedures. UV quartz cuvettes are traditionally used for DNA/RNA quantification at OD260/OD280 because they transmit UV wavelengths below 340 nm. IR quartz extends to 3,500 nm for near-IR applications. Optical Path Length The standard 10 mm path length follows the Beer-Lambert law at normal sample concentrations. Semi-micro (5 mm path) and micro-volume cuvettes (1 mm path, or internal volumes down to 10&ndash;70 &micro;L) are used for precious or limited-volume samples. The path length directly multiplies absorbance: a 1 mm cuvette gives 1/10 the absorbance of a 10 mm cuvette for the same solution &mdash; account for this in Beer-Lambert calculations. Volume: Macro vs. Semi-Micro vs. Micro Macro cuvettes (1&ndash;4 mL) are the standard for routine spectrophotometry. Semi-micro cuvettes (0.5&ndash;1.5 mL) reduce sample consumption. Micro cuvettes (10&ndash;350 &micro;L) are used when sample volume is limited; sub-micro cuvettes (10 &micro;L or less) suit precious clinical or research samples. Confirm that your spectrophotometer's beam height and aperture are compatible with the cuvette format before purchasing micro formats. Two-Window vs. Four-Window Standard cuvettes have two optically clear windows (the light-entry and exit faces) and two frosted or ribbed side walls for gripping. Four-window (all-clear) cuvettes are required for fluorescence measurements at 90&deg; to the excitation beam &mdash; the two additional clear windows allow emitted fluorescence to exit perpendicular to the excitation path. Confirm whether your instrument requires a standard or fluorescence-grade cuvette. Reusable vs. Disposable Quartz and glass cuvettes are reusable; their higher up-front cost&nbsp;is justified for low-throughput precision work or when solvents or UV wavelengths are required. Plastic cuvettes cost fractions of a cent per use and eliminate washing time in high-throughput assay workflows. Select disposable plastic for any routine colorimetric assay (Bradford, BCA, ELISA plate reader backup, OD600 bacterial growth) where wavelengths stay in the visible range. 
<h2 dir="ltr"> Specifications Context</h2>
&nbsp;
The 10 mm path length standard cuvette has internal dimensions of 10 &times; 10 mm cross-section and an internal height of approximately 45 mm. Outer dimensions are 12.5 &times; 12.5 mm, fitting all standard spectrophotometer cell holders. Window parallelism tolerance is &plusmn;0.01 mm for precision quartz cuvettes; standard optical glass cuvettes have &plusmn;0.1 mm tolerance. Light transmission through UV quartz: &gt;90% at 220 nm and &gt;85% at 200 nm. For nucleic acid quantification, a UV quartz cuvette with a minimum path length of 10 mm is required for OD 260/280 measurements; the ratio of OD260/OD280 should be 1.8&ndash;2.0 for pure DNA and 1.9&ndash;2.1 for pure RNA as a purity indicator. As of 2026, plastic disposable cuvettes remain the most cost-efficient choice for labs running &gt;50 absorbance readings per day in the visible range.

<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.

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.

&nbsp;
<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; 
If you&rsquo;re choosing between glass and plastic or trying to match the right size to your workflow, it&rsquo;s worth getting that part right early &mdash; it makes everything downstream smoother and a lot less messy. <a href="https://mbpinc.net/contact-us">Contact the MBP team now!</a>
