    Tips: Where are UV-VIS spectrophotometers used?

    The UV-Visible spectrophotometer is an instrument that measures the spectrophotometric luminosity of water according to the different wavelengths of different substances under the refraction of light. It is widely used in laboratories for the detection of liquid luminosity, and it is also one of the basic experimental instruments in the laboratory.

    UV-VIS spectrophotometer is an instrument that uses spectrophotometry to detect liquids and can detect multiple sets of data at a time. Generally, a group of distilled water is placed in the first group as a standard group, and the photometric value is set to 0, while the other groups are the control group, and the values are compared according to the value of the standard group. In addition to the use in the laboratory, this instrument has been used very frequently in food factories, quality inspection offices, water affairs bureaus, and other areas. It is mainly used to detect the presence of certain bacteria in water, food, and industrial pigments whether it exceeds the standards.
