Screw- Cap Mininert™ Valves for Vials

These convenient screw-cap Mininert® valves for vials are available in a variety of sizes. The crimp-top valve for 13 mm ID glassware slides into the neck of the vial and features a threaded flange which is turned to provide a leak-tight fit.

Temperature
Mininert valves can be used at temperatures up to 105° F. However, after use at high temperatures, the valve may leak slightly when cooled to room temperature.

Materials
Mininert valves are made from PTFE, which is highly inert and may be used with most common materials. It is particularly useful for working with most acids and organic solvents. However, problems may be encountered when used with organometallics and some strong bases. We recommend actual exposure tests before use with any material.

Pressure
The sealing ability of Mininert valves is more than adequate to contain most volatile liquids and gases at low pressures. Mininert valves have been used at pressures as high as 120 psi without leakage, but it is not recommended to pressurize glass containers to these levels. Such pressurization of glass containers can be extremely dangerous.
