Thermo Scientific* Mininert Valves

Excellent closures for chemicals that deteriorate or evaporate through conventional vial caps and seals. Thermo Scientific™ Mininert™ Valves are screw caps that have integrated resealable valves to allow repeated and unlimited syringe-needle access to samples. Slide the valve one way to open the needle-port. Slide the valve back to close and completely seal the close.
