HPLC / UHPLC / FPLC Valves

Valves for eluent selection, sample injection, column selection and more. 


Valves are ubiquitous in all HPLC and UHPLC 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.
