Puncture bag stopper or vial only once for multiple withdrawls or injections.
All are needle free. Operate with any syringe.
PIN 1 clamps onto the vial; eliminates pulling against a vacuum; and extends the life of the vial medication because all incoming air is filtered. Use on 20mm and 28mm vials.
PIN 3 greatly speeds up the process of filling syringes from a bag. The bag is punctured only once with the spike; thereby extending the life of the fluids by withdrawing from the bag through the needle free adapter; rather than through a needle.
