It contains a large number of instruments: iron frame tables, asbestos nets, alcohol lamps and other experimental tools. It is usually equipped with a chemical medicine cabinet, which contains commonly used chemicals. The central experimental table is the main component of laboratory furniture and is suitable for being placed in the middle of the laboratory. It is the main platform for conducting experimental activities. The application number is 202021528743.3, a new multifunctional experimental table for university chemical experiments, including a storage cabinet body and a test workbench. The test workbench is installed at the upper end of the storage cabinet body, and a foot cup is arranged at the bottom of the storage cabinet body. The test A storage rack is arranged on the outer wall of the upper end near the rear side of the workbench. Six new classification storage devices are added to the storage rack of the multifunctional test bench for chemistry experiments of the university. The six classification storage devices can slide left and right on the storage horizontal plate through the sleeve slide groove, so that the storage horizontal plate is divided into six separate storage spaces, and the size of each storage space can be adjusted by sliding the classification storage device. In this way, the experimental items placed on the storage horizontal plate can be placed in different areas according to their categories, thereby increasing the flexibility and functionality of the entire storage rack. The six classification storage devices can not only play the role of classification storage.

[0003] The above-mentioned multifunctional test bench for chemical experiments also has the following defects: when performing chemical experiment operations on the table, it is necessary to use glass test tubes of various specifications to hold chemical experiment samples and reagents, and then select a suitable caliber from the many different calibers of the glass test tubes on the placement rack to put them in for storage. However, in actual operation, the glass test tubes are prone to have small differences in apertures, and it is difficult to select a suitable placement port from the many placement calibers, resulting in the problem of inconvenient and inefficient test tube storage. For this reason, we propose a multifunctional test bench for chemical experiments. Utility Model Content
