Vial Screw Caps are for externally threaded sample tubes and feature long skirts and a super-fast thread design that allows them to be removed or sealed with single turn.
Provide unique, practical seals that are ideal for chemicals that deteriorate or evaporate in conventionally sealed containers with the Thermo Scientific™ Mininert Valves.
Prevent septa push through and over- and under-tightening. With AVCS built into these 9 mm screw caps you will get an optimal, consistent seal every time.
