GL38 CAP WITH INTEGRATED AIR INLET VALVE
Closed System Design
Reduce exposure to hazardous chemical vapors with Vaplock solvent reservoir caps. Minimizing evaporation, an integrated check valve permits air to enter the bottle for vacuum displacement while solvent is pumped to the instrument. A 50μm PTFE Filter covers the valve assembly to reduce particulates.
1/4-28 Port Threads
Designed to accept industry-standard 1/4-28 threaded fittings. For use with semi-rigid tubing equal to or less than 1/8” outside diameter.
Anti-Twist Design
To prevent twisting of tubing when the cap is removed or attached, the inner body rotates independently of the outer collar.
Chemically Compatible
Constructed of inert PTFE, the body of the cap provides ideal chemical compatibility with laboratory solvents. The air inlet valve is assembled with PTFE and 300-series stainless steel components, with Viton, inert FFKM, or white USP class VI EPDM seal options. Under normal use, the outer Polypropylene collar is non-wetted. Caps may be autoclaved to 140°C. Please inquire for other material options and custom designs.
