Mininert Valves

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.

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.

• Available in two sizes — 20mm (thread size 20/400) and 27mm (thread size 24/400) to fit 3 and 5mL Reacti-Vial Small Reaction Vials and 40mL Screw Cap Septum Vials, respectively
• Precision crafted from PTFE plastic for repeated use and chemical resistance
• Valve design eliminates the septum-boring that occurs with repeated puncture of traditional septa
