Safety Waste Caps & Exhaust Filters

Analytical Sales & Services offers a wide variety of Safety Waste screw caps for almost all waste containers on the market. Caps are made from polypropylene with a secondary inner PTFE Core. As with our mobile phase caps, the 2-part design means your tubing will never be twisted and tangled when attaching your waste cap to its waste container. Caps are available with GL45, S51/55, B53, S60/61, B83, or S90 threads configuration, and can handle flow rates up to 500mL. All of the safety waste caps come standard with one port for an exhaust filter, and can accommodate various sized tubing. Exhaust filters are sold separately in 3-, 6- and 12-month sizes, and come with expiry timers. Custom cap options are available, so please let us know if you need something special.
