Evacuated blood collection tubes with heparin are used for plasma determination in chemistry
Tubes are sterile
Blood is drawn directly from the vein into the evacuated sterile collection tubes
Only one venipuncture is needed to draw multiple samples
Tubes can be changed while needle and plastic holder remain in place on patient's arm
Safety shield designed for safer tube handling
Rubber stopper is recessed inside the plastic shield, so any drops left by a blood collection needle remain isolated from potential contact
Shield is designed to protect lab personnel from direct contact with blood on the stopper or around the outer rim of the tube, as well as from blood splattering upon opening the tube
