Screw Cap Mininert™ Valve for vials with a 20-400 screw thread.

Unique push-button PTFE vial closure featuring inertness and syringe access without exposure of the vial contents. • When used with a glass vial, only PTFE and glass are in contact with the sample. A silicone rubber gasket above the PTFE valve stem (isolated from the contents) provides a seal for the needle and prevents leakage or exposure of the contents during sampling. • Push the green button to open, insert the needle and take the sample, withdraw the needle, then push the red button to close. • The needle seal septum may be replaced as needed with the valve closed to avoid exposing the contents. • Mininert™ valves can be used up to 105°C.
