The Pentrex Cap Features:
Reduces risk of cross-contamination
Helps prevent evaporation and spills
Allows easier access and measuring of liquid in containers
Replaces original screw-on caps
Penetrex Caps make liquid storage and dispensing safer and easier. Contents of bottles, flasks and other containers are easily accessible using a regular leuer tip syringe or needle, but are protected from the risk of spill, evaporation and contamination. Allows for multiple penetrations. Simply insert a tip into the seal, aspirate a measured volume and remove the tip. The Penetrex Cap instantly reseals.
