The capillary tube uses capillary action to draw the blood into the micro tube thereby eliminating the tendency for scooping. Because the capillary tube is also coated with anticoagulant, the blood sample begins mixing immediately with it. When filled end-to-end, the length of the capillary tube defines a specific amount of collected blood. This results in tissue-free samples, reduced clotting, accurate sample volume and ultimately, fewer redraws and increased comfort.
