7725i manual injection valve is the most popular injection valve and used in the market now.

Feature:

*Its continuous flow design, can keep the phase flow smooth while changing-over injecting and setting, reduce the disturbution of the system under the transient presure.

*Wide 30 degree port, easy for connection.

*Single point pressure regulation, reduces friction between rotor gasket and stator, prolonging service life.,

*A built-in sensing switch, provides a reproducible start signal for the chromatograph

*Make-Before-Break technology, reduce the pressure fluctuation while load-inject changing-over .

*The Max tolerable temperature: 80oc

*The max tolerable pressure: 48Mpa

*Material: 316L, Vespel

*Range of PH: 0-10, if ph below 10, we can use PEEK material

*Optional 2 microliter built-in ultriamicro quantitative tube and accessories
