Electric rotary or selector valve is a stepper motor driven fluid handling valve designed for automated fluidics applications. The precise rotary valve provides automated routing of fluidic volumes for aggressive fluids. With small dead volumes and accurate positioning systems, they are widely used in analytical instruments for precision liquid handling, such as mass spectrometers, HPLC, In vitro diagnostics (IVD), particle analyzers, automatic reagent delivery, elemental analyzers etc. We offer a cost-effective solution to build your fluid handling module in the instrument design or laboratory experiments. 6-way, 8-way, 10-way, 12-way and 16-way electric rotary valves are available for order. Rotary valve customization is also welcomed.
