Liquid chromatograph manual injection valve (Rheodyne 7725i for example) Product Features
1. Non-stop flow design
The MBB structure keeps the mobile phase continuous when switching between sampling and injection, avoiding the interference of instantaneous pressure fluctuations on the column and detector, ensuring baseline stability and data accuracy.
2. Reduced pressure shock
pressure fluctuation at switching moment is reduced by more than 50%, especially suitable for high sensitivity analysis (e.g. trace detection) and high pressure system (e.g. UHPLC).
3. Highly accurate pressure adjustment and seal control
Single-point pressure adjustment: The pressure adjustment knob is integrated at the back of the handle, which controls the contact pressure between the rotor gasket and stator through a single point, reducing friction loss and extending the seal life to more than 100,000 times.
Wide pressure tolerance range: Supporting working pressure of 35.0MPa (5000psi), the maximum tolerance pressure is 48MPa, adapting to the diversified needs from routine analysis to ultra-high pressure.
4. Corrosion-resistant material and wide compatibility
Core material: valve body is made of 316 stainless steel, rotor is made of Vespel, which is resistant to high temperature (80ºC) and chemical corrosion.
Expanded pH application range:
Standard configuration supports pH 0-10;
Optional rotor made of PEEK, resistant to pH 0-14, suitable for strong alkaline mobile phase or samples (e.g. buffer systems in biopharmaceuticals).
5. Intelligence and ease of operation
Built-in position sensing switch: Provides repeatable electronic trigger signals to ensure that the injection action is synchronized with the chromatograph data acquisition, reducing human error.
Ergonomic design:
30-degree wide port design for quick connection of piping;
Support manual operation or remote motorized control, adapted to automated workstations.
6. Flexible Configuration and Expandability
Diversified quantitative tube:
Standard configuration of 20μL quantitative tube, support 1-5μL micro-sampling;
Optional 2μL ultra-micro quantitative tube to meet the needs of trace analysis.
Multi-channel models: 6-pass, 10-pass and other models are available to meet the needs of different flow paths (e.g. multi-column or complex method development).
7. High reliability and easy maintenance
Long-life seals: Optimized seal structure design with low-friction materials reduces maintenance frequency.
Quick maintenance module: rotor gasket and stator support quick replacement, reducing downtime.

We attach importance to packaging protection and carefully design and optimize the solution:
1, sturdy and durable: use high strength and wear-resistant materials, such as high-quality cardboard boxes, foam, etc., to protect the goods in all aspects.
2, Waterproof and moisture-proof: Designed with waterproof layer to protect the goods from moisture.
3, Shockproof and cushioning: the internal filling is precisely calculated to both cushion and save space, ensuring stable transportation. 4,Environmentally friendly material selection: use recyclable or degradable materials to reduce environmental impact.
founded in 2015 and is located in the scenic Nanchang Hi-Tech Industrial Development Zone. We specialize in providing high-quality laboratory equipment and extensive technical support worldwide. Our main products cover five core areas: chromatograph, spectrometers, general-purpose instruments, laboratory furniture and life science instruments. Chromatograph and spectrometers, such as High Performance Liquid Chromatograph (HPLC), Atomic Absorption Spectrometer (AAS), Inductively Coupled Plasma Emission Spectrometer (ICP-OES), etc., are unique in the environmental monitoring and material science industries due to their excellent analytical capabilities and stability. General-purpose instruments, including high-precision pipettes, thermostats, etc., ensure that every experimental operation can achieve the perfect combination of precision and efficiency. Laboratory furniture, incorporating modern design concepts and safety standards, provides researchers with an aesthetically pleasing as well as practical working environment. Life science instruments, such as PCR instruments and gel imaging analyzers, help the cutting-edge research in the field of life science.
