HPLC Valves

HPLC valves are required for many actions in chromatography, almost always involving switching or injecting a medium. Manually or automatically driven, the valves provide accurate direction of eluents or samples in the chromatography system from medium injection to fractionation or serve as sample providers for the LC-HPLC system.

All HPLC valves are also available in the material PEEK, however, the maximum operating pressure is somewhat lower than for stainless steel valves.

Stainless steel HPLC valve for sample injection for analytical and semi-preparative chromatography. Depending on the sample volume, sample loops from 5 µL to 5 mL, at an operating pressure of up to 400 bar, can be connected.
