Valve drive with 6 port 2 position valve V 2.1S

Valves are ubiquitous in all liquid chromatography applications. They act like a switch and can control the flow path of the chromatography system in various ways. Therefore, valves are indispensable for eluent selection, sample injection, column selection, and fractionation as well as any switching task. KNAUER valves are designed for a wide range of chromatographic and dosing applications. Flexibility is provided by choice of different materials and sizes as well as drivers for various software packages. Valves are driven either manually or automatically through a valve drive.

All valves include suitable fittings. Additionally, valves with two positions include an injection port for injection and the 12-port and 16-port valve include tubing for fractionation.
