The Vaplock™ closed system design reduces chemical evaporation and exposure to hazardous vapors with Vaplock™ solvent reservoir caps.

• Anti-twist design prevents twisting of tubing when the cap is attached or removed as the inner body rotates independently of the outer collar
• Chemical compatibility with laboratory solvents

Durable port threads are designed to accept industry-standard 1/4-28 threaded fittings. Some caps include robust stainless steel thread inserts to minimize cross-threading and damage to soft PTFE ports. For use with semi-rigid tubing equal to or less than ¹/₈" (3.2 mm) O.D.

Chemically compatible caps are constructed of inert PTFE. The body of the cap provides ideal chemical compatibility with laboratory solvents. Under normal use, the outer PP collar is non-wetted. Caps may be autoclaved to 140 °C. Combine with secure fluid connections and Vaplock air inlet or relief valves to maintain pressure equilibrium within the bottle.
