Product Description
Return unused mobile phase to the reservoir without breaking the helium-sparged environment. This cap supports recirculation alongside filtration, degassing and delivery, so labs can conserve solvent and reduce waste without sacrificing the degassing that keeps their chromatography stable. It also tidies tubing at the reservoir.
This listing is for Kimble catalog number 953983-0047: ULTRA-WARE Five Valve Recirculation and Filtration Caps, Non THF Resistant. Made from glass-filled PTFE, the cap performs stepwise filtration, sparging, storage and delivery. An integral check valve keeps mobile phase out of gas lines, and a pressure release valve prevents accidental over-pressurization. Connections use 1/4-28 fittings. This is the standard, non-THF-resistant 47 mm version. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
