VICI Valco C55VICI Valco’s Cheminert C55 Series Injectors are compact assemblies specifically designed for OEM systems. Using the Cheminert HPLC injector design and the 24-volt motor from VICI Valco’s microelectric actuators, the C55 only needs to be connected to the instrument’s power supply. Control requires a single momentary contact closure, which steps the valve to the next position; a separate contact closure moves the valve to position 1 (Home). The optional Serial Interface board permits RS232 communications for both position input control and confirmation of valve position. A low-pressure solvent selector/fraction collector version is also available. –
