Chromatography Valve

Valves are ubiquitous in Chromatography experiments. 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. Common valves used in chromatography systems include: Inlet valves for sample loading, Outlet valves for waste and fraction collectors, Injection valves for introducing precise sample volume to the column, Column valves that may include reverse flow or bypass functionality, Filter and pH calibration valves, Loop valves, Manual diaphragm valves, and Mixer valves.
