Is colorimetric cup an important part of ultraviolet-visible spectrophotometer?



Is colorimetric cup an important part of ultraviolet-visible spectrophotometer? If you want to know this question, please read the following articles carefully.

Industry experts said that the colorimetric cup is an important part of the ultraviolet-visible spectrophotometer; the colorimetric cup can be divided into quartz cup, glass cup and plastic cup according to material properties; and then according to different measurement volumes, there are colorimetric cup and capillary colorimetric cup; usually testing nucleic acid and ultraviolet quantitative protein, we need to use quartz cup and glass, after all, the dyes in the reaction can make quartz and glass. Colouring; and that's why common plastic cups are not suitable for testing samples in the ultraviolet range.



In addition, many times, due to the different amount of test samples, many manufacturers of ultraviolet-visible spectrophotometer provide different equipment volumetric colorimetric cups; now there is a kind of plastic cup which can be used not only for nucleic acid, but also for ultraviolet protein quantitative determination, the amount of sample only needs 50 ml; what we need to know is that with the development of life science and related science. With the development of science, higher requirements have been put forward for the experimental research of this kind of science. Spectrophotometer has become an indispensable instrument in molecular biology laboratory, and it is also one of the necessary equipment in microorganism, food and pharmaceutical laboratories.
