Mininert® Valves

Mininert valves are available for both screw top and crimp top vials. Mininert push-buttom valves are highly dependable, leak-tight closures for vial and other laboratory containers. When used with a glass vial, only PTFE and glass are in contact with the contents.
Operation is extremely simple - push the green button to open the valve, insert the needle through the septum and take a sample, withdraw the needle, and push the red button to close the valve.

Valves are available in the following sizes: 13/425, 15/425, 18/400, 24,400 and 20 mm crimp top.
