The RVM microfluidics rotary valve is a precise OEM low-pressure electric rotary valve designed for automated microfluidic applications. The RVM microfluidics rotary valve series, renowned for its small channels and ultra-precise positioning system, offers unrivaled precision in liquid management within microfluidic set-ups. Opt for dead-volume-free operation, enabling precise fluid control for your experiments.
Available in various configurations: Distribution with 8, 10, 12, or 24 ports, Switching with 4 or 6 ports, and On/Off.
Includes the RVM valve, USB cable, and power supply (fittings not included).
General
This OEM microfluidics rotary valve is a precise low-pressure electric rotary valve designed for automated microfluidic applications. Its small channels and accurate positioning system are ideal for precise liquid handling.
Showing an unrivaled small wetted volume and exceptional ease of use, this valve is the perfect companion for liquid distribution in your instrument or laboratory experiments at a reduced cost. This fast version is the best for your time-specific applications, with a rotation time of only 400 ms for 180°.
Advantages
The RVM is used for sample preparation, multiplexing, injection, distribution, and is adapted for point-of-care devices. Compact and light, it is easy to use and integrate with various external control options.
Fast liquid switching: This extremely small internal volume selection valve allows to rapidly switch liquid while maintaining an ultra-low carryover.
Ultra-low internal volume: The unique precise valves exhibit an internal volume (port-to-port) down to 2.5 μL due to their exceptionally small 0.5 mm diameter channels.
Integrated sensor: The position sensor is directly integrated into the valve to ensure precise positioning (even with clearance on the motor axis and potential wear!). An automatic procedure at power-up allows the valve to know its precise location. This is called the «homing».
Choice of motor: The RVM valve is available either in low-power version, or fast version (rotation of 180° in only 400 ms). The fast version is the standard for the RVM, the lower-power version is available on request.
