Mininert - Model Screw- Cap -Valves for Vials
Mininert valves for vials are convenient screw-cap mechanisms available in various sizes, designed to ensure a secure seal for glassware with crimp-top finishes. Constructed from PTFE, these valves exhibit a high degree of chemical inertness, making them suitable for use with most acids and organic solvents, though caution is advised when dealing with organometallic compounds or strong bases. They perform effectively at temperatures up to 105°F, but may experience slight leakage upon cooling from elevated temperatures. The Mininert valves are proficient in containing volatile liquids and gases at low pressures, having been tested successfully up to 120 psi, though this is not recommended for glass containers due to the risk of breakage. Users are advised to conduct exposure assessments to verify compatibility with specific materials before use. The versatility and reliability of these valves cater to a variety of laboratory and analytical applications, particularly in handling sensitive and reactive substances safely.Most popular related searches

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.
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.
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.
