Description

Technical Field

[0001] The utility model relates to the field of chemical reagent mixing equipment, in particular to a mixing device for chemical reagents. Background Art

[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are an important condition for scientific and technological progress and are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. They can be said to be the eyes of chemists. In the daily work of factories, schools, hospitals and research institutes, chemical reagents are indispensable. Various chemical substances can be prepared by mixing multiple chemical reagents, and the commonly used tools for preparing chemical reagents are generally test tubes.

[0003] When mixing chemical reagents in test tubes, the test tubes are traditionally shaken or stirred with a long stick. However, since the outer wall of the test tube is slippery, manual mixing can easily cause the test tube to slip, and the long stick needs to be washed with water after stirring, which is rather troublesome. Therefore, a mixing device for chemical reagents is proposed to solve the above problems. Utility Model Content
