SAFE-T-FILL Capillary Plastic Blood Collection Tubes, EDTA, 125 uL, Purple (50/Box) - SAFE-T-FILL Capillary Blood Collection Tubes are used to collect capillary blood samples from finger and heel sticks. Pre-assembled with a capillary straw, attached pierceable cap, and a microtube, SAFE-T-FILL improves the quality of capillary blood samples. Hemolysis and tissue contamination are avoided by drawing the blood sample into the microtube through capillary action rather than trying to drop the blood into the microtube by milking or scooping. Clotting is prevented by having anticoagulant in both the capillary straw as well as the microtube allowing the blood sample to begin mixing immediately as it is drawn into the tube. Available in a wide variety of sizes and additives and through all major distributors.
