Waters, 700000254, PERFORMANCE PLUS SAPPHIRE CHECK VALVE CARTRIDGE (2)

The PerformancePLUS™ Check Valve Cartridges are used with pumps that have the PerformancePLUS Cartridge Check Valve System installed. The PerformancePLUS Cartridge Check Valve System can be used as either an inlet or outlet valve in the Waters 1515, 1525, 515, and 600 HPLC pumps. The inlet check valves of the 2695, 2695D and the 2795 are also the PerformancePlus type. The check valve materials have been carefully specified for solvent compatibility with all HPLC mobile phases. The housing features a two-piece design that allows it to be removed so that the cartridge can be changed without disturbing the fitting on the housing.

Waters PerformancePLUS™ Sapphire Check Valve Cartridges are replacement fluidic components for compatible HPLC pumps fitted with the PerformancePLUS cartridge check-valve system. The pack contains two cartridges used to maintain one-way solvent flow and dependable pump priming during chromatographic operation. The design supports specified inlet or outlet locations in Waters 1515, 1525, 515 and 600 pumps and selected inlet configurations of 2695, 2695D and 2795 separation modules. A two-piece check-valve housing permits cartridge replacement without disturbing the fitting connected to the housing. Maintaining healthy check valves helps reduce flow instability, pressure fluctuations and retention-time variation associated with worn or contaminated valves. The package contains valve cartridges rather than a complete replacement pump.
