The spectrophotometer is a scientific instrument that decomposes light with complex components into spectral lines. Spectrophotometry is a qualitative or quantitative analysis of a substance based on the absorbance of light at a specific wavelength or within a certain wavelength range. Spectrophotometers have become a routine instrument in modern molecular biology laboratories.

Common technical parameters of spectrophotometers include wavelength range, spectral bandwidth, wavelength accuracy, stray light and other indicators. In fact, in quantitative analysis, a sufficient wavelength range is enough. A wavelength range that is too wide is not only useless, but also increases the failure factors of the instrument. There will be some differences in qualitative scanning due to the high or low of indicator parameters such as spectral bandwidth, wavelength accuracy and stray light, but there is actually no significant difference in the quantitative analysis process. The automatic sampling function can bring real safety and convenience benefits to laboratory personnel.

Automatic visible spectrophotometer can be widely used in water supply, environmental protection, disease control, atmosphere, third-party testing, chemical industry, quality inspection, scientific research institutions etc.. It is one of the ideal quality inspection instruments in the field of analytical testing and a necessary instrument for conventional laboratories.
