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 green for easy identification
Made of polyethylene terephthalate (PET)
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
