Main Features

Features of High Pressure Constant Flow Pump:

Automatic pump self-test when turned on, automatic fault diagnosis, built-in high and low pressure protection functions with alarm.

Patented "self-priming check valve" technology increases O-ring life.

Conveniently change the operating mode of the pump by closing external contacts.

All pump head components are designed to be individually disassembled for easy maintenance.

Automatic pump head flushing function - the pump can supply fluid without manually removing air.

Automatic recognition of pump head type and intelligent adjustment of parameters.

Full pre-rinse function for quick solvent changes.

Wide range of pump heads: analytical, semi-preparative and preparative.

Programmable solvent compressibility coefficient for automatic flow compensation.

All components are easily accessible for maintenance and repair.

Built-in software control of gradient elution: ability to edit and store up to 60 gradient methods, execution of complex gradient programs.

Pump parameters can be controlled from both the pump panel and the system controller, providing flexibility in a variety of operating conditions.

Features of the Wavelength Tunable UV Detector

Automatic self-test when turned on; Built-in security, alarm and automatic troubleshooting functions.

Optical system with precision positioning and unique heat dissipation technology; highly efficient optical system and digital filtering.

Light source: deuterium lamp or tungsten lamp (optional); The service life of a deuterium lamp is 1000 Hrs.

Imported light sources; When replacing the lamp, no adjustment of the optical axis is required, which simplifies maintenance.

Real-time display of flow cell and reference cell energy for easy monitoring of light source and flow cell status.

Online monitoring and display of light source operating time to assess the remaining lamp life.

High-brightness OLED display - stable and aesthetic display of information.

Multi-range signal output for analysis of various concentrations.

Zero setting function: The optical density can be zeroed either from the detector panel or automatically through the software.

Wavelength setting: control via keyboard or software; Fully sealed integrated photodetector that requires no mechanical adjustment when selecting or changing wavelength.

Specialized flow cells are provided for microvolume, semipreparative and preparative analyses, and their replacement is simple and convenient.

High versatility of the device, wide range of applications in various fields of scientific research.
