Application

Mininert valves are leak-tight closures for vials and other containers. They are available in both crimp and screw thread versions. Only PTFE and glass are in contact with the contents of the container. They are the ideal closure for the following applications:

• calibration standards
• air- or moisture-sensitive fluids
• derivatizating reagents
• volatile chemicals

Other Notes

The maximum temperature that Mininert Valves can be used at is 105° F. When Mininert Valves are used at high temperatures, returning them to room temperature may cause the valve to leak slightly.Mininert is a registered trademark of Valco Instruments Co. Inc.
