The Solvent Waste system also features a closed-loop design, which protects against leaks and spills, improving overall lab safety. Each Solvent Waste System comes with one 83mm or 120mm open VersaCap, fittings, plugs for unused ports, a replaceable sulfur-cured EPDM gasket, and a chemical exhaust filter. * Depending on application, carbon exhaust filter life cycle may vary.
