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
Closures are color coded
Made of polyethylene terephthalate (PET)
With 3.2% buffered sodium citrate solution
Provide a safer work environment for all personnel by (1) reducing risk of tube breakage during handling; (2) eliminating breakage when tubes are centrifuged at higher speeds; and (3) eliminating breakage or chipping of tube rims when stopper is removed and reinserted
In addition to reducing potential injuries, fewer tube breakages result in less workflow interruption and fewer patient redraws, providing smoother day-to-day operation
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
