Provide unique, practical seals that are ideal for chemicals that deteriorate or evaporate in conventionally sealed containers with the Thermo Scientific™ Mininert Valves. Constructed of chemical-resistant PTFE coating, they provide an inert, leak-tight, high-pressure seal. The easy-to-use push button valve allows repeated and unlimited syringe-needle access to samples and eliminates the septum-boring that occurs with repeated puncture of traditional septa. Valves are available to fit Thermo Scientific™ Reacti-Vial™ Small Reaction Vials and Thermo Scientific™ Screw Cap Septum Vials.
