The Correct Syringe Needle is Neccessary for Proper Performance

Merlin MicroSeal Compatible Syringe Needles

With proper use, including using the correct syringe needle outer diameter (23-gauge, 0.63mm) and needle termination (truncated cone or blunt tip), the life of a Merlin MicroSeal can be thousands of injections. Sharp edged or sharp pointed needles can pierce and damage the duckbill valve. The 23-26 gauge tapered needles also will not work properly because the 26-gauge part of the needle opens the duckbill before the 23-gauge part can seal with the O-ring.
