Capillary Blood Collection Tubes with Sodium Heparin - Micro-Hematocrit Glass Tubes 1000/Box

Professional Micro-Hematocrit Glass Capillary Blood Collection Tubes with Sodium Heparin Anticoagulant

These precision-engineered capillary blood collection tubes represent the clinical standard for accurate micro-hematocrit determinations and safe blood specimen collection. Each tube is manufactured from treated soda lime glass and pre-loaded with sodium heparin anticoagulant, making them ideal for finger stick blood collection procedures and processing untreated whole blood samples in laboratory and point-of-care settings.

Advanced Anticoagulant Technology

Pre-treated with pharmaceutical-grade sodium heparin anticoagulant, these tubes prevent blood coagulation immediately upon sample collection, ensuring specimen integrity throughout the testing process. The heparin coating is uniformly distributed along the interior surface, providing consistent anticoagulation performance across the entire sample volume. This eliminates the need for manual anticoagulant addition, reducing preparation time and minimizing the risk of dosing errors that could compromise test accuracy.

Color-Coded Identification System

Each tube features a distinctive red stripe color-coding system that enables rapid visual differentiation between heparinized and untreated tubes. This critical safety feature prevents specimen mix-ups in busy clinical environments, supports proper workflow organization, and ensures compliance with laboratory standard operating procedures. The permanent, fade-resistant stripe remains clearly visible throughout specimen processing, storage, and centrifugation.

Precision-Molded Soda Lime Glass Construction

Manufactured from high-quality precision-molded soda lime glass, these capillary tubes deliver exceptional dimensional consistency and structural integrity. The uniform bore diameter ensures accurate sample volume measurement, while the smooth interior surface promotes complete sample recovery and prevents hemolysis during collection. The robust glass construction maintains specimen containment even under high-speed centrifugation forces, eliminating the risk of tube breakage, sample loss, or laboratory contamination.

Rapid Fill Technology for Specimen Integrity

Engineered with optimized capillary action properties, these tubes fill rapidly and completely through simple contact with the blood source. The controlled fill rate prevents air bubble entrapment and maintains red blood cell integrity, ensuring that micro-hematocrit readings accurately reflect the patient's true hematocrit value. Fast, reliable filling reduces patient discomfort during finger stick procedures and minimizes the risk of sample clotting before collection is complete.

Clinical Applications & Use Cases

Perfect for a wide range of diagnostic applications including micro-hematocrit determinations, packed cell volume measurements, pediatric blood collection where sample volume is limited, point-of-care testing in clinical settings, field research applications, and veterinary diagnostics. The sodium heparin anticoagulant makes these tubes particularly well-suited for chemistry panels, electrolyte analysis, and other tests requiring plasma separation from whole blood specimens.
