Description

Technical Field

[0001] The utility model relates to the field of chemical experiments, in particular to a chemical experiment table which is convenient for classified storage. Background Art

[0002] Chemistry is a basic natural science that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels. It originates from life and production practice, and its natural laws are closely related to the physical and chemical properties of matter and materials in the macroscopic world where humans live. As an important bridge between the microscopic and macroscopic material worlds, chemistry is one of the main methods and means for humans to understand and transform the material world. When doing chemical experiments, a chemical laboratory bench is often used, which is an important operating platform used in chemical experiments.

[0003] Most of the experimental reagents on the existing chemical laboratory table are placed directly on the table. When conducting chemical experiments, the reagents are taken directly on the table, which makes the placement of chemical reagents on the table rather messy. In addition, if the reagents in the experimental bottles splash during the experiment, it is easy to contaminate the reagent bottles on the table, and it will also cause additional risks.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
