Cole-Parmer® VapLock™ Solvent Delivery Caps

Reduce chemical evaporation and exposure to hazardous vapors
  • Use with semi-rigid tubing equal to or less than 1/8" (3.2 mm) OD
Create a closed system using solvent reservoir caps to prevent hazardous vapors from escaping into the lab. Caps accept standard 1/4"-28 UNF(M) fittings to easily connect semi-rigid tubing. Anti-twist design allows the inner body of the cap to rotate independently preventing tubes from tangling when caps are removed or attached. Caps are constructed of PTFE body and PP collar* and are autoclavable.

Caps with threaded port have ports angled at 10° tilt for more accessible tubing connections. Select caps with stainless steel (SS) thread insert to minimize cross-threading and damage to soft PTFE ports.

*Does not come in contact with liquid under normal circumstances.
