Sample Cups

<h2 dir="ltr">What are Automation Sample Cups?</h2>
 Automation sample cups (also called analyzer sample cups, autosampler cups, or J-cups) are small-volume polystyrene or polypropylene vessels designed to hold aliquoted patient specimens for direct loading into automated clinical chemistry analyzers, immunoassay platforms, hematology analyzers, and ICP-MS/ICP-OES spectrometers. They are used when an analyzer's primary tube handler cannot directly aspirate from a standard 15 mL or 50 mL collection tube&mdash;typically because the sample volume is insufficient, a diluted aliquot is required, or a specific cup geometry is mandated by the instrument's sampling needle. Globe Scientific offers the largest selection of alternate (OEM-equivalent) sample cups for laboratory analyzers, providing significant per-cup savings versus manufacturer-supplied consumables. Choose analyzer sample cups by instrument model first&mdash;dimensional compatibility is non-negotiable&mdash;then optimize for material (PS for optical clarity, PP for chemical resistance) and volume.

<h2 dir="ltr"> How to Choose Automation Sample Cups</h2>
 Instrument Compatibility: Dimensional Match is Mandatory Automation sample cups must match the exact outer diameter, height, and cup-bottom geometry specified by the instrument manufacturer. A cup that is 0.5 mm too wide or too narrow will not seat correctly in the autosampler rotor, causing aspiration failures, pipetting errors, or instrument alarms. Globe Scientific engineers and validates each alternate cup to OEM specifications for named analyzer platforms; confirm the instrument model against the catalog's compatibility list before ordering. Volume: 0.5 mL vs. 1.5 mL vs. 2.0 mL 0.5 mL cups (13.55 &times; 24.50 mm, polystyrene) are used on chemistry analyzers including Beckman CX series, Alpha Wassermann, Bio-Chem Labs, and DPC Immulite platforms. 1.5 mL cups (13.8 &times; 22.60 mm) are used on BioMerieux AG-2/ASCA and MLA 1600C platforms. Larger 2.0 mL cups are used on Roche cobas and Horiba ABX platforms. The minimum working volume of the cup must exceed the analyzer's dead volume (typically 150&ndash;400 &micro;L) plus the required sample volume. Material: Polystyrene vs. Polypropylene Polystyrene (PS) sample cups provide excellent optical clarity for colorimetric-based analyzers that photometrically read the cup contents and have low protein adsorption for routine chemistry analytes. Polypropylene (PP) cups are used when the sample contains organic solvents, strong acids (trace element analysis), or when acid-wash protocols are required for ICP-MS autosampler systems. MoldPro and Globe Scientific PP autosampler cups for PerkinElmer, Agilent, and Shimadzu ICP systems are manufactured from virgin PP with ultra-low metal content verified by ICP-MS lot testing. With or Without Caps/Inserts Sample cups with caps are used when the aliquot must be sealed to prevent evaporation or cross-contamination during batch loading. Insert cups (smaller inner cup that sits inside a standard tube) allow aliquoted samples to be loaded directly without relabeling &mdash; a common efficiency gain in high-volume core labs. Confirm whether your instrument's autosampler accepts capped cups or requires open-top formats. ICP-MS vs. Clinical Chemistry Applications ICP-MS autosampler cups require certified ultra-low metal content (verified by ICP-MS at ppb level), manufactured from virgin PP without metal-containing additives, dyes, or fillers. Standard PS clinical chemistry cups contain low-level metal additives from colorants and should not be used for trace element or heavy metal analysis. Always use metal-free certified cups for any elemental analysis application. 
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific analyzer sample cups are manufactured to exact OEM specifications and provide equivalent precision and optical properties to original manufacturer cups. PS cups have optical clarity with &ge;90% light transmission in the visible spectrum, required for photometric analyzers. PP ICP-MS autosampler cups meet ultra-low metal content specifications: typically &lt;1 ppb for Fe, Zn, Cu, Pb, Mn, and other analytes commonly measured in trace element panels. Cup dimensions are held to &plusmn;0.1 mm tolerance on O.D. to ensure consistent seating in autosampler rotors. As of 2026, Globe Scientific is the most widely stocked alternate analyzer consumable brand through lab distributors, including MBP, offering per-cup savings of 20&ndash;40% versus OEM pricing for high-volume clinical labs.

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).

</ul>
<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.

Microcentrifuges

<h2>What Are Microcentrifuges?</h2>
&nbsp;
Microcentrifuges are compact, high-speed benchtop centrifuges designed specifically for 0.2&ndash;2.0 mL microtubes and PCR strips, operating at 10,000&ndash;21,000 &times;g in a fixed-angle rotor. They are the primary centrifugation instrument in molecular biology, biochemistry, and clinical molecular diagnostics labs: nucleic acid pellet formation after ethanol precipitation, spin-column DNA/RNA extraction and PCR cleanup steps (typically specified at 10,000&ndash;16,000 &times;g for 30&ndash;60 seconds), cell debris clearance from lysates, protein precipitation supernatant recovery, and brief sample clarification before downstream analysis. Standard benchtop microcentrifuges reach 14,000&ndash;15,000 RPM (16,000&ndash;21,000 &times;g), while high-speed models reach up to 21,000 RPM and approximately 31,000 &times;g. Refrigerated variants maintain 0&ndash;4&deg;C for temperature-sensitive workflows.

&nbsp;
<h2>How to Choose a Microcentrifuge</h2>
&nbsp;
Maximum RCF vs. Protocol Requirements
Most spin-column kit protocols specify 10,000&ndash;16,000 &times;g. A standard microcentrifuge reaching 14,000&ndash;16,000 &times;g covers these requirements. If your lab performs alcohol-precipitation DNA/RNA pelleting (12,000&ndash;16,000 &times;g) or virus concentration steps (20,000+ &times;g), choose a model reaching at least 16,000 &times;g. High-speed models reaching 21,000&ndash;31,000 &times;g are available for specialized applications.
Rotor Tube Positions and Capacity
Most microcentrifuge rotors hold 12&ndash;24 &times; 1.5/2.0 mL tubes per run. Laboratories processing larger batches benefit from 24-position rotors, while smaller research groups may find 12-position models sufficient. Confirm that adapters for 0.5 mL and 0.2 mL tubes are available if required by your workflows.
Refrigerated vs. Ambient Temperature
Refrigerated microcentrifuges are recommended for RNA extraction, protein stability studies, cell viability applications, and any protocol requiring 4&deg;C centrifugation. Standard room-temperature models are suitable for routine DNA extraction and PCR cleanup procedures.
Noise Level and Footprint
Modern brushless DC motor microcentrifuges typically operate at &le;52 dB, making them quieter than older brush-motor systems. Most units occupy 200&ndash;300 mm of bench width, so confirm that sufficient clearance is available when the lid is fully open.
Safety Features
Essential safety features include lid-lock mechanisms, imbalance detection, and over-speed protection. Laboratories handling infectious materials should verify that aerosol-tight sealed rotor lids are available for the selected model.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
The standard spin-column step in most commercial DNA/RNA extraction kits specifies 10,000&ndash;16,000 &times;g for 30&ndash;60 seconds. Always confirm the rotor's maximum RCF from manufacturer specifications, since RPM values alone do not account for differences in rotor radius.
Microcentrifuge rotors are typically fixed-angle designs positioned at approximately 45&deg;, providing efficient pelleting and short sedimentation paths. Aerosol-tight sealed lids allow safe handling of BSL-2 samples and other applications requiring biocontainment. Modern brushless DC motors offer quieter performance, improved speed accuracy, and longer service intervals than legacy brush-motor systems.

ESR System Accessories

<h2 dir="ltr">What are ESR System Accessories?</h2>
 ESR system accessories are the racks, stands, pipettes, funnels, leveling platforms, and sealing clay items required to perform the Westergren erythrocyte sedimentation rate (ESR) test at the bench. While the ESR test itself measures red blood cell sedimentation over 60 minutes, the accuracy of the result depends entirely on the precision of the supporting accessories: the pipette must be held at exactly 0&ndash;2&deg; of vertical, the rack must rest on a leveled surface free from vibration, and the vial seal must prevent both evaporation and aerosol escape.&nbsp;

<h2 dir="ltr"> How to Choose ESR System Accessories</h2>
 Rack Type and Tube Capacity ESR racks hold Westergren pipettes in a perfectly vertical position for the full 60-minute incubation. The Sedi-Rate&trade; rack (Globe Scientific catalog 3452) uses support clamps that hold polystyrene pipettes (graduated 0&ndash;180 mm) vertically within &plusmn;2&deg;, accommodating standard batch sizes of 10&ndash;20 samples. When used in conjunction with the acrylic leveling platform (catalog 3459), the rack delivers the vertical alignment mandated by ICSH. Racks made from polycarbonate (PC) are vibration-resistant and suitable for high-traffic clinical bench environments. ESR Pipettes: Self-Zeroing vs. Manual Fill The Sedi-Rate&trade; polystyrene pipette features a unique fibrous plug at the zero mark (0 mm) that auto-zeroes blood draw while acting as a self-sealing aerosol barrier, preventing hazardous substances from escaping through the top. This eliminates the manual zeroing step and the open-tube aspiration required by glass Westergren tubes, reducing biohazard exposure. Manual glass Westergren tubes (300 mm, 2.5 mm bore) require separate zeroing with a bulb or aspirator and are the ICSH reference format, but involve open-tube blood handling. Vials and Self-Sealing Stoppers The Sedi-Rate&trade; PP vial has a patented self-sealing stopper that is pierced by a transfer pipette or funnel for blood loading, then reseals to contain the specimen. This closed-vial format reduces aerosol risk versus open glass tube loading. The vial accommodates 1.6 mL of sodium citrate-anticoagulated blood loaded through the stopper without opening the tube. Leveling Platform Accurate ESR results require the pipette to be vertical to within &plusmn;2&deg; and the bench surface to be vibration-free and level. The acrylic leveling platform (catalog 3459) fits under the Sedi-Rate&trade; rack and has adjustable feet and a bubble level indicator to confirm proper surface leveling before the 60-minute incubation begins. Temperature during incubation must be 18&ndash;25 &deg;C; placing the rack near centrifuges, heating units, or air conditioning vents introduces thermal artifacts. Starter Kit vs. Individual Components The Sedi-Rate&trade; Westergren Starter Kit (Globe Scientific) includes 100 test kits (vials + pipettes), one rack, one leveling support, and a set of funnels &mdash; the fastest way to set up a new ESR testing station. Individual accessory reorders (pipettes, vials, racks, funnels, sealing clay) are available separately for established labs restocking consumable components. 
<h2 dir="ltr"> Specifications Context</h2>
 The Sedi-Rate&trade; system uses polystyrene pipettes graduated from 0 to 180 mm, compatible with the ICSH modified Westergren method for EDTA-anticoagulated blood diluted 4:1 with 0.85% saline. Rack support holes hold pipettes vertically within &plusmn;2&deg;, the maximum permitted deviation per ICSH guidelines; deviation beyond &plusmn;2&deg; increases ESR by up to 30% at 5&deg; tilt.

Weighing Dishes & Boats

<h2 data-section-id="4vlupf" data-start="410" data-end="461">What Are Laboratory Weighing Dishes and Funnels?</h2>
&nbsp;
Laboratory weighing dishes and funnels are disposable antistatic consumables used in gravimetric sample preparation&mdash;where solid or liquid materials are weighed on analytical or top-loading balances before being transferred into reaction vessels, volumetric flasks, or tubes. Weighing dishes (also called weigh boats or pour boats) are flat-bottomed antistatic polystyrene containers used to hold samples on the balance pan during weighing. Weighing funnels are antistatic polypropylene tools with one flat side for stability on the balance and a conical stem designed to fit flask necks, allowing complete quantitative transfer of material with minimal loss. Globe Scientific offers antistatic PS weighing dishes in square, hexagonal, and pour-boat formats ranging from 10 mL to 350 mL, and antistatic PP weighing funnels in extra-small through extra-extra-large sizes. Both are single-use only because washing removes antistatic properties and affects weighing accuracy.

<h2 data-section-id="1yz3s79" data-start="1436" data-end="1480">How to Choose Weighing Dishes and Funnels</h2>
&nbsp;
Weighing Dish Shape
Square weigh boats are used for routine laboratory weighing and are designed with sloping sides and recessed corners to minimize sample loss during transfer. Hexagonal weigh boats provide better stability on balance pans due to their molded edges and also offer improved grip during handling, making them suitable for workflows where stability matters. Pour-boat designs include a built-in spout that allows controlled and accurate dispensing of liquids or viscous samples into receiving vessels without spillage.
Weighing Dish Capacity
Small 10&ndash;20 mL dishes are used for micro-scale weighing of reagents typically under 2 g on analytical balances. Medium 50&ndash;100 mL dishes are used for routine laboratory weighing of 2&ndash;20 g samples. Large 200&ndash;350 mL dishes are used for bulk powders and higher-volume transfers on top-loading balances.
Weighing Funnel Size
Extra-small funnels are used for 5&ndash;20 mL vessels and microtubes, small funnels for 20&ndash;50 mL, medium funnels for 50&ndash;200 mL, large funnels for 200&ndash;500 mL, and extra-large funnels for 500&ndash;1000 mL flasks. The flat side ensures stable placement on the balance pan during weighing before transfer.
Color: White vs. Black
White dishes provide high contrast for dark or strongly colored samples, making them easier to visualize during transfer. Black dishes are used for light-colored or transparent samples where residue visibility is important, especially when confirming complete sample recovery.

Storage Bottles

<h2 data-section-id="1nhmff" data-start="0" data-end="39">What Are Laboratory Storage Bottles?</h2>
&nbsp;
Laboratory storage bottles are precision-molded plastic vessels used to store, transport, and dispense liquid and solid reagents, solvents, buffers, and samples across a wide range of laboratory workflows. Globe Scientific's Diamond RealSeal bottle range includes wash mouth bottles, wide mouth bottles, and narrow mouth bottles. Wash mouth bottles are flexible LDPE squeeze bottles available in 250&ndash;1000 mL sizes for glassware rinsing and solvent dispensing. Wide mouth bottles, available in HDPE and PP from 30 mL to 2 L, are designed for powders, viscous liquids, and bulk sample storage. Narrow mouth bottles, including Boston round styles in HDPE, LDPE, and PP, range from 4 mL to 8 L and are used for liquid reagents, sampling, and chemical storage. All Diamond RealSeal bottles are manufactured from virgin FDA 21 CFR-compliant resins and feature PP integral-seal closures that provide leak-proof performance without separate liners or gaskets. LDPE is best suited for squeeze-action wash bottles, HDPE is the standard choice for general liquid storage, and PP should be selected whenever autoclave sterilization is required.

&nbsp;
<h2 data-section-id="e7a0da" data-start="1174" data-end="1217">How to Choose Laboratory Storage Bottles</h2>
&nbsp;
Mouth Size: Wash, Wide, or Narrow
Wash mouth bottles feature integrated dispensing nozzles or draw tubes that allow controlled squeeze-action delivery and are primarily used for rinsing and dispensing liquids rather than long-term storage. Wide mouth bottles, with openings typically greater than 38 mm, allow easy filling and dispensing of powders, granules, viscous liquids, and larger samples. Narrow mouth bottles, including Boston round designs, provide controlled pouring, reduced evaporation, and secure storage for liquid reagents and solvents.
Material Match
LDPE is the preferred material for wash bottles because of its flexibility and squeeze performance. HDPE provides broad chemical resistance, low leachables, and a temperature range suitable for most laboratory chemicals and reagents, making it the standard choice for general storage. PP is selected when bottles must withstand autoclave sterilization at 121&deg;C or be used for media preparation and sterile workflows. Amber HDPE and amber PP bottles are recommended for light-sensitive compounds that require protection from UV and visible light exposure.
Volume
Small bottles ranging from 4&ndash;30 mL are commonly used for reference standards, analytical reagents, and sample collection. Mid-range bottles from 60&ndash;500 mL are suitable for daily-use reagents, calibration standards, and working solutions. Larger bottles from 1&ndash;8 L are typically used for bulk reagent storage, media preparation, and buffer stock solutions.
Closure Type
Diamond RealSeal PP closures incorporate an integral seal ring that creates a leak-proof closure without requiring separate liners or gaskets. Standard PP screw caps are used throughout the Diamond Essentials economy line. For autoclavable PP bottles, caps should be loosened during sterilization and tightened after cooling to maintain proper sealing performance.
