About this item
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.
