Capillary Tubes

<h2 dir="ltr">What are Capillary Tubes? </h2>
 Capillary tubes for laboratory use are thin-walled, open-ended tubes&mdash;typically 75 mm long with an internal diameter of 1.1&ndash;1.2 mm&mdash;that collect microvolume blood samples (40&ndash;80 &micro;L) by capillary action from finger-stick or heel-stick punctures, directly from anticoagulated blood collection tubes, or from blood gas analyzers. They are the primary consumables for the micro-hematocrit (packed cell volume, PCV) determination: tubes are filled, sealed, centrifuged at 10,000&ndash;14,500 RPM for 5 minutes, and the ratio of packed red cells to total blood column is read against a hematocrit chart. Globe Scientific manufactures both soda lime glass and plastic (unbreakable) micro-hematocrit capillary tubes, as well as pre-calibrated borosilicate glass tubes for blood gas applications. Choose heparinized capillary tubes for direct finger-stick collection from untreated blood; choose plain (untreated) tubes when filling from an anticoagulated blood collection tube.

<h2 dir="ltr"> How to Choose Capillary Tubes</h2>
 Plain vs. Heparinized Plain capillary tubes (blue tip, Globe Scientific) are used when filling from a pre-anticoagulated specimen (EDTA or citrate blood collection tube). Heparinized tubes prevent clotting in samples collected directly from a skin puncture: ammonium heparin&ndash;coated tubes (green tip) and sodium heparin&ndash;coated tubes (red tip) are both available. The tip color is the universal identifier &mdash; confirm the coding convention with your supplier before ordering, as some manufacturers reverse the color assignments. Glass vs. Plastic Soda lime glass capillary tubes (Globe Scientific catalog 51602&ndash;51607) provide excellent capillary action, low surface adsorption, and superior optical clarity for reading the hematocrit column. Plastic capillary tubes (catalog 51620) eliminate the sharps hazard from glass breakage during centrifugation&mdash;a significant occupational safety consideration for high-volume clinical labs processing hundreds of hematocrit determinations daily. Both formats fit standard 75 mm hematocrit centrifuges. Pre-Calibrated (Blood Gas) Tubes Pre-calibrated borosilicate glass capillary tubes (Globe Scientific catalog 51628, I.D. 0.55 mm &plusmn; 0.03 mm) are precision-ground for blood gas and co-oximetry analyzers requiring specific internal volume tolerance. These differ from standard hematocrit tubes in inner diameter; using the wrong tube in a blood gas analyzer causes instrument error codes and inaccurate analyte results. Centrifuge Compatibility All 75 mm micro-hematocrit capillary tubes are compatible with standard hematocrit centrifuges rated for 10,000&ndash;14,500 RPM. Confirm your centrifuge head accepts the tube O.D. (1.5 mm &plusmn; 0.05 mm for Globe Scientific glass tubes) before ordering in bulk.
<h2 dir="ltr"> Specifications Context</h2>
 Globe Scientific soda lime glass micro-hematocrit capillary tubes have an I.D. of 1.15 mm &plusmn; 0.05 mm, O.D. of 1.5 mm &plusmn; 0.05 mm, and a length of 75 mm &plusmn; 1 mm, with a fill volume of approximately 75 &micro;L. The standard centrifugation protocol is 10,000&ndash;14,500 RPM for 5 minutes in a dedicated hematocrit centrifuge. Normal hematocrit ranges: 38&ndash;50% for adult males, 35&ndash;47% for adult females; values outside this range, combined with elevated ESR and other CBC parameters, are used to evaluate anemia, polycythemia, and inflammatory conditions. As of 2026, Globe Scientific is an ISO 9001:2015&ndash;certified manufacturer and MBP-stocked supplier of both glass and plastic capillary tube formats.

<h2>What are Blood Collection Tubes for Nucleic Acid Research?</h2>
&nbsp;
Blood collection tubes for nucleic acid research are evacuated tubes pre-filled with a lysis reagent or anticoagulant that preserve DNA and/or RNA from whole blood specimens collected by standard venipuncture. On blood draw, the lysis reagent immediately inactivates nucleases and preserves both genomic DNA and RNA&mdash;including transcriptomic expression profiles&mdash;from 3&ndash;6 mL of mammalian whole blood. They are used in gene expression analysis, next-generation sequencing, PCR-based molecular diagnostics, cell-free DNA (cfDNA) studies, and biobank archiving. Choose blood collection tubes specifically formulated for nucleic acid preservation when the sample cannot be processed within 2&ndash;4 hours of draw.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Vacuum blood collection tubes for standardized sample volumes</li>
<li>Capillary blood collection tubes for small-volume sampling</li>
<li>Pediatric and micro-collection tubes for difficult draws</li>
<li>Sterile single-use blood collection tubes for diagnostic safety</li>
<li>General-purpose clinical and laboratory blood sampling tubes</li>
</ul>
&nbsp;
<h2>How to Choose Blood Collection Tubes</h2>
&nbsp;
DNA vs RNA vs Dual Preservation
K2 EDTA tubes (lavender cap) prevent clotting and preserve cellular morphology for CBC and flow cytometry, but RNA degrades rapidly without additional stabilization. Blood RNA stabilization tubes preserve intracellular RNA expression profiles, while dual-preservation blood collection tubes stabilize both DNA and RNA simultaneously, enabling downstream molecular analysis from a single specimen.
Blood Volume Per Tube
Standard blood collection tubes typically hold 3 mL or 6 mL. Confirm the draw volume against your extraction kit's minimum input requirement. Many NGS and RT-PCR extraction kits require 1&ndash;3 mL of whole blood per reaction, making 3 mL tubes sufficient for many single downstream applications.
Processing Window
For immediate processing (within 2 hours), standard K2 EDTA tubes are generally suitable. For delayed processing or sample shipment, choose blood collection tubes specifically formulated to stabilize nucleic acids according to the manufacturer's validated storage conditions.
Anticoagulant Type
K2 EDTA is the preferred anticoagulant for most molecular biology applications, including PCR and NGS. K3 EDTA may be used in some automated laboratory systems. Heparin is a known PCR inhibitor and should generally be avoided for nucleic acid workflows. Citrate tubes are not typically used for nucleic acid preservation.
Regulatory Compliance
For clinical or regulatory-submission workflows, confirm whether the blood collection tube has the appropriate regulatory approval or clearance for your intended application. Research-use-only (RUO) products are not intended for diagnostic use unless specifically authorized.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Standard evacuated blood collection tubes are commonly manufactured from medical-grade PET or glass. K2 EDTA tubes should be gently inverted 8&ndash;10 times immediately after collection to ensure complete anticoagulant mixing. Nucleic acid preservation tubes are available for both immediate processing and stabilized transport, depending on the manufacturer. DNA and RNA yield varies with donor characteristics, collection volume, storage conditions, and the extraction method used.

Storage Boxes & Racks

<h2 data-section-id="1hv97bw" data-start="0" data-end="47">What Are Laboratory Storage Boxes and Racks?</h2>
&nbsp;
Laboratory storage boxes and racks are essential organizational systems used to store, organize, and protect cryogenic vials, microcentrifuge tubes, centrifuge tubes, and microscope slides across freezers, cold rooms, and benchtop environments. Storage boxes are typically lidded, grid-based containers used for long-term sample organization in ultra-low temperature conditions, while racks are open-frame supports used for active handling during laboratory workflows such as pipetting, vortexing, and reaction setup.
Cryogenic storage boxes are commonly designed to hold 81 vials (9&times;9 format) or 100 vials (10&times;10 format), and are compatible with storage conditions ranging from &ndash;196 &deg;C in liquid nitrogen vapor phase to +121 &deg;C for autoclave sterilization (depending on material). Tube racks, on the other hand, provide stable upright positioning of tubes during active benchwork and are not primarily intended for long-term freezer storage.

<h2 data-section-id="flyrii" data-start="1159" data-end="1199">How to Choose Storage Boxes and Racks</h2>
&nbsp;
Vial Format and Capacity
The first selection criterion is compatibility with tube size and grid layout. The most common format is the 81-place (9&times;9) box designed for 1.0&ndash;2.0 mL cryovials. Smaller or specialized formats may accommodate 5 mL tubes or different vial diameters depending on grid spacing. Proper matching ensures secure fit, easy retrieval, and consistent sample organization in high-density storage systems.
Temperature Range
Material selection determines allowable storage conditions. Polycarbonate cryogenic boxes are the most versatile, supporting temperatures from liquid nitrogen levels (&ndash;196 &deg;C) through &ndash;80 &deg;C freezer storage and up to autoclave sterilization at +121 &deg;C. Cardboard freezer boxes with moisture-resistant coating are designed for economical freezer storage and can withstand ultra-low temperatures, but they are not suitable for autoclaving or long-term moisture exposure.
Tube Rack Materials and Use
Polypropylene racks are widely used because they are autoclavable and chemically resistant, making them suitable for sterile workflows. ABS and polystyrene racks provide lower-cost alternatives for general laboratory bench use but are not designed for autoclave conditions. For freezer organization, stainless steel racks are often used to hold multiple cryoboxes within &ndash;80 &deg;C upright freezer systems, improving accessibility and spatial organization.
Slide Storage Boxes
Microscope slide storage boxes are designed to protect standard 25 &times; 75 mm slides. They are available in 25-, 50-, and 100-slide capacities. Polypropylene versions are autoclavable and suitable for sterilized workflows, while fiberboard or ABS versions are typically used for room-temperature archival storage and transport.
Color Coding and Sample Identification
Color-coded storage boxes are widely used in biobanking and high-throughput laboratories to quickly differentiate sample groups without opening boxes or reading labels at freezer temperatures. Common systems include multiple lid colors paired with alphanumeric grids inside the box, enabling precise sample tracking and retrieval in large inventories.
&nbsp;
<h2 data-section-id="1jl751w" data-start="4067" data-end="4092">Specifications Context</h2>
&nbsp;
Modern polycarbonate cryogenic storage boxes are engineered for extreme temperature stability, typically rated from &ndash;196 &deg;C to +121 &deg;C, allowing use across liquid nitrogen vapor phase storage, &ndash;80 &deg;C freezers, and autoclave sterilization cycles. Cardboard freezer boxes are coated to resist moisture ingress and are optimized for cost-efficient high-density storage in ultra-low temperature environments.
The 81-place (9&times;9 grid) polycarbonate cryobox remains the standard format in most biorepositories and clinical research facilities due to its compatibility with SBS footprint freezer systems and automated inventory tracking workflows. These systems are widely used in genomics, cell banking, and pharmaceutical research environments.
