A roll of 100 individually stripped, sealed, 1-1/2 in. cannulas packaged in a handy dispenser pack. These economical, disposable cannulas fit both Luer-slip and Luer-lock syringe. Since only one cannula at a time is exposed, the remaining stay free of contamination. This gives maximum protection against contamination by allowing you to tear open the cellophane and place a fresh cannula on the dosage bottle without ever touching the cannula.
