Reagent bottle tray is an auxiliary teaching tool used in chemical experiment teaching to standardize the storage of reagents. It is often made of acid and alkali resistant plastic or wooden materials, and has grooves of different sizes on the surface to fix different specifications of reagent bottles. In teaching, it can sort and place scattered reagent bottles in an orderly manner to avoid tipping or confusion. During the experiment, the tray facilitates the overall transportation of reagents, reducing the risk of collision during retrieval, and is particularly suitable for classroom group experiment distribution. It is a practical tool for experimental preparation, operation, and organization, which not only ensures experimental safety but also cultivates students' sense of organization and standardization.
