■innovate
The high-pressure infusion pump adopts electronic pulsation suppression technology, replacing traditional mechanical buffers and completely solving major failures caused by frequent leakage of mechanical buffers. In addition, the adoption of this new technology has also minimized the dead volume of the infusion system.
The wavelength positioning method of the multi wavelength ultraviolet spectrophotometer is directly achieved by the microcontroller through controlling the rotation of the grating (i.e. the sine relationship between wavelength and grating angle is implemented through software), replacing the traditional sine rod mechanism (monochromator), overcoming the wavelength positioning error caused by mechanical wear and backlash of the screw drive, and also overcoming the monochromator collision accident caused by misoperation.
