The Right Valve for HPLC, UHPLC and FPLC
Valves for special applications like multi-injection modes or column selection and backflushing.
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. In many cases, a 2-position or a multiposition valve is the right choice. Whenever their function reaches its limits, an intelligent solution must be developed. The design of KNAUER´s special position valves is customized to an application. At the moment, we offer special position valves for multi-injection modes or column selection and reverse flow with only one valve.
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.

Applications for Special Position Valves
Whenever a 2-position or a multiposition valve is not enough
