CHROMWARE three valve cap reservoir systems ( BP-1925 ) consist of a three valve cap, TORNADO HPLC reservoir, stainless steel inlet filters, and fittings. To filter HPLC mobile phases directly into the reservoir, purchase filtration/degassing cap ( BP-1915-047 ) and a mobile phase pickup adapter ( BP-1904-048 ).
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.
