The 3725i manual injection valve 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, greatly 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.
The MBB (Make Before Break) technology with built-in position sensing switch provides a reproducible start signal for the chromatograph, effectively reducing pressure fluctuations at the moment of load subject switching.
- Maximum temperature tolerance: 80 ℃
- Maximum withstand pressure: 48Mpa
- Material: 316 stainless steel, Vespel (rotor)
- PH range: 0-10
(If using samples or mobile phases with pH>10, PEEK material rotors can be selected, which can withstand pH 0-14)

main features
Equipped with a standard working pressure of 34MPa, it can be easily adjusted to 48MPa high pressure mode through the pressure adjustment knob at the back of the handle, adapting to a wider range of mobile phase conditions, challenging high difficulty separation tasks, and expanding experimental possibilities.
the 7725i liquid chromatography column also has the following five functions:
- During the sampling/injection conversion, the mobile phase remains continuous (with no interruption in the flow path, as per Rheodyne's MBB technology)
- The pressure selector button behind the handle can make sealing control very easy;
- The range of pipeline connection angles has increased, making it easier to connect and use;
- Equipped with built-in trigger (position sensing switch, limited to type I suffix only);
- Optional 2 microliter built-in ultra micro quantitative tube and accessories
