Vaplock™ Wako Supply Caps, 38 mm, Cole-Parmer
Closures Safety Caps and Safety Waste Caps
The Vaplock™ closed system design reduces chemical evaporation and exposure to hazardous vapors with Vaplock™ closed system solvent reservoir caps.

  • Anti-Twist design prevents twisting of tubing when the cap is attached or removed
  • 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. The anti-twist design prevents twisting of tubing when the cap is removed or attached, as the inner body rotates independently of the outer collar.

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.
