High automation


Wavelength selection, temperature control and semiconductor cooling are controlled through software.


Modular Structure: Attractive and Reasonable Design


High-Performance Variable Wavelength UV-Vis Detector

• High sensitivity, low noise and drift


• New optical design, concave holographic gratings provide


high repeatability


• Wide wavelength range, multi-wavelength programming,


full wavelength scanning with continuous flow, can


accurately select optimal analysis wavelength


• R232 data interface

• Long lifespan deuterium lamp, typical lifespan of 2000


hours or more

Precise thermostatic column oven


•  Large volume oven can accommodate manual injector and any two columns (15 cm, 25 cm, 30 cm).


•  Advanced temperature control suitable for low temperature separation of biological samples


•  Precise temperature control, temperature display in status panel, overheating alarm and protection (automatic shutdown).

Six-Way Valve

Six-way valve injection is compatible with international standards; easy to use, low noise, accurate injection.

P-101A High-Pressure Pump


•  This dual piston reciprocating high-pressure pump delivers a high precision steady flow. High quality sealing rings are resistant to wear, pressure and corrosion. Patented pulse dampeners ensure effective dampening. Gradient elution is controlled by software.


•  Low pulse, large flow range, continuously adjustable flow, high flow repeatability, accessible solvent replacement.


•  Features pressure monitoring and safety mechanisms, programmed control of flow and time.


•  Easy maintenance: pumps are easy to clean, repair and maintain, plunger rods and seals are accessible for cleaning and easily replaceable. Cleaning plunger rods will minimize abrasion caused by deposition of salt buffer solutions.

LC Software

•  Easy to use and intuitive, controls pump and detector


•  Powerful data processing capabilities that features a variety of quantitative algorithms.


•  Strong chromatogram comparison function


•  Features calibration curve correction


•  High degree of automation: the whole process from data collection to report printing is automated. A series of chromatograms can be saved into files for convenient management.


•  Raw chromatogram collection data and related information are recorded in compliance with GLP Standards.


•  Flexible design of report output formats


•  Set instrument information according to requirements
