Rheodyne manual injection valve is the most advanced and widely used injection valve in the market at present, especially the 7725i model, which has a very high precision and accuracy. The range of injection quantity can be 1 μ l to 5 μ L; the normal working pressure is set to 34mpa, and the working pressure can be adjusted to 48mpa by adjusting the pressure button behind the handle.

1. Rheodyne's continuous flow (MBB) structure design patent can maintain the continuity of flow during sampling and injection switching, greatly reducing the interference of instantaneous pressure impact on the system.

2. Wide 30 degree port, easy to connect with connector.

3. Single point pressure regulation reduces the friction between the rotor gasket and the stator, and prolongs the service life.

4. The patented MBB (make before break) technology can effectively reduce the pressure fluctuation at the moment of load inject switching.

5. With built-in trigger, it can trigger automatically to ensure time synchronization and reduce error;
