Mininert valvesfrom VICI Precision Sampling • Valves for vials • Valves with standard tapers • Valves with threaded fittings • Replacement septa and • septum installation tool • Mininert syringe valves Mininert® push-button valves are highly dependable, leak-tight closures for screw-cap vials and other laboratory containers. When used with a glass vial, only PTFE and glass are in contact with the contents. Their unique features make Mininert valves the ideal closure for calibration standards, air- or moisture-sensitive fluids, derivatizing reagents, or volatile chemicals. 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. Temperature: Mininert valves can be used at temperature up to 105°F. However, after use at high temperatures, the valve may leak slightly when cooled to room temperature. Pressure: The sealing ability of Mininert valves is more than adequate for containing most volatile liquids and gases at low pressures. Mininert valves have been used as high as 120 psi without leakage, but this is not a recommendation for pressurizing glass containers to these levels. Such pressurization of glass containers can be extremely dangerous. Chemical resistance: PTFE is highly inert and may be used with most common materials. It is particularly useful for working with most acids and organic solvents. Problems may be encountered when used with organometallics and some strong bases. We recommend actual exposure tests before use with any material. 
Valves for vialsModels are available for screw-cap and crimp-top vials. The screw-cap Mininert is available in 13, 15, 18, 20, and 24 mm cap 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. Cap sizes available: 13 mm, 15 mm, 18 mm, 20 mm, 24 mm, crimp top
Valves with standard tapersThe laboratory taper model brings Mininert convenience and ease to a variety of applications using standard laboratory glassware, such as reaction chambers, test tubes, and other glass systems. Tapers available: 14/20, 19/22
Valves with threaded fittingsOur threaded designs offer positive on/off fluid control as an in-line valve or syringe access as a termination valve at a sample point. In-line valves are 1/4-28 male to male or 1/4-28 female to female. Termination valves are offered in 1/4-28 male or female and 1/8" NPT male or female. In-line valves: 1/4-28 male to male and 1/4-28 female to female Termination valves: 1/4-28 male, 1/4-28 female, 1/8" NPT male, and 1/8" NPT female
Replacement septa and septum installation toolThese silicone septa fit all Mininert valves. The installation tool is a handy device for quickly removing and replacing needle seal septa.
Mininert syringe valvesThese convenient add-on valves allow our Series C and D syringes to store samples at up to 250 psi. The valve body is all PTFE, with a stainless steel stem. Also available to fit luer-tip syringes from any manufacturer and accept traditional luer needles.
