Mobile Phase Bottle Safety Caps

Laboratory safety is very important to Analytical Sales and Services, Inc. Our mobile phase screw caps are made from high quality polypropylene with machined PTFE centers. Tubing lines are held in place with secure finger tight fittings, and will no longer become tangled upon removal of the cap because of the 2-part design (threaded portion spins independently of the center). There is an additional O-ring between the Teflon center and cap surface to ensure no evaporation. Most mobile phase screw caps come standard with replaceable air check valves. Safety caps are available in GL38, GL45, S55, and B83 threads.

Call us to design your custom mobile phase cap, at no extra charge.
