SP Wilmad-LabGlass CHROMWARE® THF-Resistant Three Valve Cap Reservoir Systems, SP Industries
CHROMWARE® Three Valve Reservoir Systems are recommended for applications where on-off control of all three ports on the cap is necessary.

For example, HPLC mobile phases for several labs can be filtered and degassed at a central location, sealed with a three valve cap with the internal inlet filters and tubing connections already in place, and delivered to the HPLC stations ready-for-use.

Furthermore, after an HPLC run is completed, all three valves on each reservoir can be closed to maintain the mobile phase in a sealed environment until the next run. Tetrahydrofuran (THF), which is widely used as a mobile phase for GPC, attacks the Viton® O-rings of the standard CHROMWARE® systems. The integrated and three valve cap systems have been made into THF-resistant systems by replacing all Viton® O-rings with Kalrez® O-rings, and replacing the standard stainless steel inlet filters with CTFE components, with conventional all-stainless-steel filters.

NOTE: To filter HPLC mobile phases directly into the reservoir, use filtration/degassing cap (BP-1915-047) and a mobile phase pickup adapter (BP-1904-048). Each each sold separately.
