CP Lab Safety 2-Port Cap with Air Inlet Valve and Plugs, For Glass Bottles with GL45 Closure, Yellow

2-port solvent delivery cap kit, gl45 with (2) 1/4-28 ports and a built-in air inlet valve. This kit includes 2 plugs for unused holes (wf-1428-plug). Choose adapters for 1/8" or 1/16" od tubing separately (part numbers wf-aq-1-8 and wf-aq-1-16). Tubing is pushed all the way through the ports and to the bottom of the reservoir before the adapter is tightened (tubing and adapters not included). the main benefit of this port cap is that the check valve has been integrated into the bottle cap, allowing air to safely enter the cap when fluid is pulled out. The check valve components are upgraded to ffkm and will resist virtually any solvent used in the laboratory. The remaining wetted surfaces are (teflon-equivalent) ptfe. closed system design reduce chemical evaporation and exposure to hazardous vapors with this solvent reservoir port cap, which uses a secure fluid connection and a built-in air inlet valve to maintain pressure equilibrium within the bottle. 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" (3.2mm) outside diameter. Ports are angled 10 for more accessible tubing connections. anti-twist design to prevent twisting of tubing when the cap is removed or attached, the inner body rotates independently of the outer collar when loosened. chemically compatible constructed of inert ptfe, the body of the cap provides ideal chemical compatibility with laboratory solvents. Under normal use, the outer polypropylene collar is non-wetted. Caps may be autoclaved to 140c. Please inquire for other material options and custom designs. 1/4-28 compression fittings designed for liquid-tight connection of semi-rigid tubing to flat-bottom 1/4-28 port threads, for tubing
