HPLC valves for injection and switching
Due to their compact dimensions, KNAUER valves need very little bench space. Valves are ubiquitous in all HPLC applications. 2-position valves are used mostly for injections, but can be used for complex switching systems as well. Multi-position valves are used for fraction collection, eluent selection or column switching.
KNAUER valve drives feature a short switching time of 150 ms to reduce pressure surges during a run. There are multiple ways of control: Directly via keypad on the device, via software with LAN or RS-232 connection or via analog control.
