RAM SCIENTIFIC SAFE-T-FILL® capillary blood collection tubes are 100% plastic capillary blood collection systems. Available for a wide range of applications, the capillary collection tubes are pre-assembled with a capillary tube, attached cap and a micro tube. 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 mixes with it immediately to prevent clotting. When filled end to end, the length of the capillary tube is equal to the stated fill volume. This results in tissue-free samples, reduced clotting, accurate sample volume and ultimately, fewer redraws and increased patient comfort. The attached cap is color coded to designate the type of additive that is in both the capillary tube and the micro tube. Since the cap is attached, the possibility of contamination or accidental loss is eliminated. The caps are pierceable and available as self-sealing.
