Product Description

Main features
1) Easy to operate, with a 5-inch visual human-machine interactive touch interface.
2) Intelligent operation, user input mode, achieving intelligent prompts for gradual input.
3) High stability, real-time encoder feedback comparison, and more stable instrument operation.
4) High degree of automation, unmanned, working 24 hours without interruption.
5) Beautiful appearance, small size, light weight, easy installation, and strong versatility.
6) The injection push rod adopts a buffering mechanism, which reduces the dead volume of injection.
7) Each operating mechanism adopts absolute position calculation to compensate for accumulated errors during operation.
8) Adopting precision motor drive, providing multiple driving speeds, stable injection speed, and precise injection quantification.
9) Provide a universal modbus communication protocol to facilitate the development of user control programs on the upper computer.
10) Safe error verification, after the user inputs data, the system verifies the data to ensure safer instrument operation.
11) The PC upper computer software is fully reverse controlled to improve user efficiency.
12) A machine can simultaneously operate two injection ports without occupying the injection ports.
13) The sample tray that can be switched left and right makes it more flexible for docking with chromatographs from different manufacturers.
The 15 bit sample tray can be expanded to 20 bit sample trays through settings.
