Shanghai Jinghua 754 UV Visible spectrophotometer (automatic)

Features
Adopting a 1200L/mm high-performance UV specific grating, long-life deuterium/tungsten lamp, photoelectric converter, and advanced C-T monochromator structure, the instrument has low stray light, high resolution, and good photometric linearity.
The spacious sample chamber can be expanded to a 10cm sample rack, thereby expanding the testing range of the instrument.
Automatic wavelength setting, automatic adjustment of 0% T/100% T, and error free conversion of T/A.
It has advanced functions such as automatic correction of wavelength errors and automatic switching of light sources, ensuring the testing accuracy and continuity of the instrument.
The instrument has functions such as photometry, quantification, and standard curves. Scanning instruments can expand regression equations, kinetics, multi wavelength, DNA/protein, and other functions.
