Blood Collection Tube
Blood collection tubes are sterile glass or plastic tubes with a vacuum inside facilitating the draw of a predetermined volume of liquid. Most commonly used to collect blood samples in venipuncture, they are designed for the collection, transport, and processing of skin puncture blood. The insides of these tubes may be coated with anticoagulants to keep blood from clotting after being drawn and stored inside the tube. Tight seals preserve sample integrity.
Tubes with a closure incorporate a plastic shield that protects lab personnel from contact with blood on the stopper or around the outer rim of the tube, and from potential splattering when tube is opened. The closure's rubber stopper is recessed inside the plastic shield to isolate blood drops left by the needle.
