7725iStainless steel injection valve
　　
Rheodyne7725iand7725The manual injection valve is currently the most advanced and widely used injection valve on the market, which adopts a quantitative ring full filling and partial filling method, and can handle1ulto5mlThe sample size. High precision.

The PatentMBB(Make-Before-Break)Technology can maintain the continuity of flow during sampling and injection switching, effectively reducingLoad-InjectSwitching between momentary pressure fluctuations. The built-in position sensing switch provides a reproducible start signal for the chromatograph
Technical parameters:
Maximum temperature tolerance:80℃
Maximum tolerable pressure:48Mpa
texture of material:316Stainless steelVespel(rotor)
pHRange:0-10(If usedpH＞10The sample or mobile phase can be selectedPEEKThe material of the rotor can withstandpH 0-14)

Main features:
7725The series of liquid chromatography injection valves have very high precision and accuracy,7725The series of liquid chromatography column injection valves have been widely used7125In addition to the various functions of the type injection valve, it also has the following five functions:

(1), take/Maintain continuity of the mobile phase during injection conversion(There is no interruption in the flow path, that isRheodyneThe company's patented technologyMBB)

(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 built-in trigger(Position sensing switch,Only applicable to suffixes ofIType injection valve;

(5), can be optionally selected2Micro liter internal ultra micro quantitative tube and accessories.
