Cryo Boxes

<h2>What Are Cryo Boxes?</h2>
&nbsp;
Cryo boxes are lidded, gridded storage containers designed to organize cryogenic vials, microcentrifuge tubes, and centrifuge tubes inside ultra-low temperature (ULT) freezers at &minus;80&deg;C, vapor-phase liquid nitrogen refrigerators (&minus;150 to &minus;190&deg;C), and cryogenic dewars. The two primary materials are water-resistant coated cardboard (economical, single-use) and rigid polycarbonate or polypropylene (reusable, autoclavable, transparent). Standard well configurations&mdash;25 (5&times;5), 81 (9&times;9), and 100 (10&times;10)&mdash;in 2-inch and 3-inch box heights match common cryogenic vial sizes. The alphanumeric grid on the lid helps with sample tracking in LIMS systems. Cardboard cryo boxes are vapor-phase LN2 rated only; polycarbonate is required for autoclave use or liquid-phase LN2 immersion.

&bull; Standard cryo boxes for cryogenic vial storage &bull; Freezer storage boxes for ultra low temperature use &bull; Cardboard cryo boxes for cost effective storage &bull; Polypropylene cryo boxes for durability and reuse &bull; Grid format boxes for easy sample organization &bull; Hinged lid cryo boxes for quick access &bull; Color coded storage boxes for sample identification &bull; Cryo storage boxes for 1.5 mL and 2.0 mL vials
&nbsp;
<h2>How to Choose Cryo Boxes</h2>
&nbsp;
Material: Cardboard vs. Polycarbonate vs. Polypropylene
Cardboard cryo boxes are economical and used for long-term storage at &minus;80&deg;C or vapor-phase LN2. They are single-use and not autoclavable. Polycarbonate (PC) boxes are durable, transparent, and autoclavable at 121&deg;C, making them suitable for frequent handling. Polypropylene (PP) boxes also tolerate autoclaving and offer higher chemical resistance than PC. Choice depends on reuse frequency and sterilization needs.
Well Count and Vial Size
81-well (9&times;9) boxes fit standard 1.8&ndash;2.0 mL cryogenic vials up to ~13 mm outer diameter. 100-well (10&times;10) boxes are used for smaller 1.2&ndash;1.5 mL vials and microcentrifuge tubes up to ~12 mm OD. Always match vial diameter with box well size before ordering.
Box Height: 2-Inch vs. 3-Inch
2-inch boxes are standard for 1&ndash;2 mL cryovials and are most commonly used in biobanking. 3-inch boxes are for larger 3&ndash;5 mL vials and certain centrifuge tubes where extra depth is required.
LN2 Phase Compatibility
Both cardboard and hard-wall boxes can be used in vapor-phase LN2. Only polycarbonate or polypropylene boxes should be used for liquid-phase LN2 because cardboard can break down when submerged.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Cryo boxes are typically rated from &minus;196&deg;C to +121&deg;C depending on material. Cardboard is suitable for vapor-phase LN2 only, while hard-wall plastic boxes can handle more demanding workflows. Proper selection depends on vial size, storage temperature, and how frequently samples are accessed.

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.

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.

</ul>
<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.

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.

</ul>
&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.

Clinical Centrifuges

<h2>What Are Clinical Centrifuges?</h2>
&nbsp;
Clinical centrifuges separate whole blood into diagnostic components&mdash;serum or plasma, red blood cells, white blood cells, and platelets&mdash;by spinning standard blood collection tubes (5&ndash;50 mL vacutainer formats) at 300&ndash;6,000 RPM (typically 3,000&ndash;3,500 &times;g) for defined cycle times. They are the core specimen-processing instrument in clinical chemistry, hematology, immunology, coagulation, and molecular diagnostic laboratories. Standard serum separation runs at 3,000 &times;g for 10 minutes after a 30-minute clotting period; plasma preparation from anticoagulated tubes runs at 2,000&ndash;3,000 &times;g for 10&ndash;15 minutes. Clinical centrifuges used in CLIA-regulated labs must meet Clinical Laboratory Improvement Amendments performance requirements and be documented for routine calibration and maintenance.

<h2>How to Choose a Clinical Centrifuge</h2>
&nbsp;
Speed Range and Maximum RCF
Most routine clinical serum and plasma preparation requires 3,000&ndash;3,500 &times;g. Clinical centrifuges with a maximum RCF of 3,500&ndash;6,000 &times;g cover all standard blood tube protocols and allow headroom for gel separator tube requirements, which vary by manufacturer. Platelet-poor plasma preparation requires up to 10,000 &times;g, making higher-speed models appropriate for coagulation laboratories.
Rotor Type: Swing-Out vs. Fixed-Angle
Swing-out rotors produce a horizontal sediment layer perpendicular to the tube wall, simplifying serum and plasma aspiration while reducing red blood cell carryover into the supernatant. Fixed-angle rotors pellet at higher RCF per RPM and are faster for pelleting applications, although the diagonal sediment interface is less convenient for aspiration. Swing-out rotors are commonly preferred for routine blood tube processing, while fixed-angle models are often selected for higher-throughput workflows.
Tube Capacity and Format
Clinical centrifuge rotors typically hold 6&ndash;24 blood collection tube positions per run. Confirm that the rotor accommodates your required tube dimensions, including 13 mm OD tubes for 5&ndash;7 mL samples and 16 mm OD tubes for 10 mL samples, and verify adapter availability for 15 mL and 50 mL conical tubes when needed.
Refrigerated vs. Room Temperature
Refrigerated models operating between 2&ndash;8&deg;C are commonly used for coagulation factors, complement panels, cryoglobulin testing, and research specimens where analyte stability is temperature-sensitive. Room-temperature centrifuges are generally sufficient for routine chemistry and immunology workflows completed within standard processing times.
Programmable Acceleration and Deceleration
Adjustable acceleration and deceleration profiles help prevent gel barrier displacement in serum separator tubes and preserve platelet and buffy coat layers in specialized protocols. Manufacturers of gel separator tubes often specify both maximum RCF and acceleration limits, making programmable controls beneficial in high-throughput environments.
CLIA and CAP Compliance
Maintain documentation for centrifuge model numbers, serial numbers, rotor identification, and calibration verification schedules. Many laboratory quality programs include periodic speed verification using a calibrated tachometer, with records retained to support audit and accreditation requirements.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Serum separation at 3,000 &times;g for 10 minutes is a commonly referenced protocol for routine chemistry and immunology testing. Gel separator tube manufacturers, including BD Vacutainer, Greiner, and Sarstedt, publish recommended RCF ranges to support proper gel barrier migration and minimize sample rejection due to displacement. Laboratory protocols should follow the specific recommendations provided for each tube type.
RCF is calculated using the formula RCF = 1.118 &times; 10&minus;5&nbsp;&times; r &times; N2, where&nbsp;r&nbsp;is the rotor radius in millimeters and&nbsp;N is RPM. Rotor-specific calculations provide more accurate results than generic RPM conversion tables. Modern clinical centrifuges commonly feature brushless DC motors, offering quieter operation, reduced maintenance requirements, and extended service life, along with programmable acceleration and deceleration settings to support sensitive specimen processing.

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. The self-sealing stopper in Sedi-Rate&trade; vials eliminates aerosol exposure during blood loading, consistent with OSHA Bloodborne Pathogens Standard 29 CFR 1910.1030 requirements for engineering controls to eliminate or minimize blood exposure. The Globe Scientific Sedi-Rate&trade; system is the primary ESR accessory line carried by MBP, alongside individual capillary tube sealing clay (catalog 5162).
