[0002] Organic synthesis refers to the process of synthesizing organic matter from simpler compounds or single substances through chemical reactions. Sometimes it also includes the process of degrading complex raw materials into simpler compounds. Due to the various characteristics of organic compounds, especially the covalent bonds between carbon and carbon, organic synthesis is relatively difficult and often requires reaction conditions such as heating, light, catalysts, organic solvents, and even pressure.

[0003] In the process of organic synthesis experiments, stirring is often required through an agitator. Due to the different specifications of different reaction vessels, the stirring area is difficult to control during the stirring process, resulting in the existing agitators being inconvenient to use and the stirring efficiency being low. To solve the above problems, we propose an agitator for use in organic synthesis experiments. Utility Model Content
