BD Vacutainer Safety-Lok Blood Collection Set 21g x .75'', 12'' Tubing with Luer adapter(green)

BD Vacutainer Safety-Lok Blood Collection Sets are sterile closed systems for drawing blood from difficult veins, such as the back of the hand, and their use helps to minimise the risk of false positives in the case of collection of blood cultures.  BD Safety-Lok have an integrated protective shield, which permanently locks over the needle after venepuncture.
