Laboratory racks must be sufficiently stable to prevent them from shaking or collapsing during experiments.

[0003] Laboratory racks provide a stable support platform for various laboratory equipment, ensuring safety and stability during experiments. A well-organized laboratory rack layout allows for efficient use of laboratory space and storage of more laboratory equipment and chemicals. Laboratory racks help researchers organize and manage experimental materials, making the experimental process more organized. Laboratory racks can separate different experimental areas to prevent interference and potential safety risks between experiments. Laboratory racks are equipped with baffles to prevent splashing and injury to operators during experiments.

[0004] The following shortcomings were found during subsequent use:

[0005] 1. When loading and unloading chemical laboratory supplies on the storage table, the baffles on both sides of the storage table will hinder this process, causing danger in the process of taking out the laboratory supplies;

[0006] 2. The position of the storage table is fixed, and the distance between the storage tables cannot be adjusted according to the size of the experimental supplies, which is inconvenient for storing experimental supplies of different sizes.

[0007] Therefore, in view of this, the existing structure was studied and improved, and an experimental stand for chemical experiments was proposed. Utility Model Content
