Manual injection valve

Rheodyne7725i manual injection valveIt is currently a widely used injection valve in the market. Its product features include:

The continuous flow (MBB) structure design of Rheodyne can maintain the continuity of flow during sampling and injection switching, reducing the interference of instantaneous pressure shock on the system.

★ Wide 30 degree port, easy to connect with connectors.

★ Single point pressure regulation reduces friction between the rotor sealing gasket and the stator, extending its service life.

Main features of Rheodyne7725i

7725 series liquid chromatography injection valveIt has very high precision and accuracy, and the injection volume can range from 1 microliter to 5 microliters; The normal working pressure is set to 34Mpa, and by adjusting the pressure button behind the handle, the working pressure can be adjusted to 48Mpa. 7725 and 7725i injection valves come standard with a 20 microliter quantitative tube. In addition to the various functions of the widely used 7125 injection valve, the 7725 series liquid chromatography column injection valve also has the following five functions:

(1) During the sampling/injection conversion, the mobile phase remains continuous (with no interruption in the flow path, as per Rheodyne's MBB technology)

(2) The pressure selector button behind the handle can make sealing control very easy;

(3) The range of pipeline connection angles has increased, making it easier to connect and use the injection valve;

(4) Equipped with an internal trigger (position sensing switch, * suffix for Type I injection valve);

(5) Optional 2 microliter built-in ultra micro quantitative tube and accessories
