[0002] Chemical titration analysis is one of the important analytical methods in our laboratory. Titration analysis is mainly used to determine the content or concentration of a substance in a solution. It adds a reagent of known concentration (called titration reagent) to make it react chemically with the substance to be measured in the test solution. The endpoint of the titration is determined according to the titration end point of the chemical reaction, that is, the observable change of the solution, such as color change, potential change or the appearance of precipitation, so as to calculate the concentration of the titrated substance.

[0003] However, in the process of chemical titration analysis, the endpoint is mainly determined by color change. The color observation will be affected by the change of external light. People are affected by the external light and observe the changes of different colors differently, which will lead to errors in the judgment of the endpoint. At the same time, the change of external light will also have a certain impact on the reading of the burette scale. Therefore, we proposed a chemical analysis titration stand and titration table device to solve the above problems. Utility Model Content
