Capillary Tube, Microhematocrit, 100% PLASTIC, Red Tip, Sodium Heparinized
These plastic micro hematocrit capillary tubes are completely unbreakable, eliminating the risk of injury and contamination associated with glass tubes due to breakage. Plastic micro hematocrit capillary tubes comply with FDA, NIOSH, CDC and OSHA safety recommendations. The tubes have an anticoagulant (sodium heparin) that keeps the blood from clotting. All of the tubes have color coded ends to easily identify the plain and heparin treated tubes.
