RVM – Rotary valve

The ultra-low internal volume rotary valve

Control and optimise your flow path

This is an OEM product. It can be tailored for the needs of your instrument.

Description

Our OEM valve is a precise low-pressure electric rotary valve designed for automated microfluidic applications. Its exceptionally small channels and accurate positioning system make it ideal for precise liquid handling.

Showing an unrivaled small wetted volume and an exceptional ease of use, this valve is the perfect companion for liquid distribution in your instrument or laboratory experiments at a reduced cost. A low power model exists for a minimum battery use and a fast one exists for your time-specific applications.
