The sliding plates 7 have operating holes 8, and the operating holes 8 are used for operators to pass through the operating holes 8 to perform experiments. After the sliding plates 7 slide on the operating holes 8, they are used to adjust the height of the operating holes 8 on the transparent plate 5.
[0036] In this embodiment, the bracket 1 of the fume hood is designed to be stably set on the ground, which helps to ensure the stability and safety of the fume hood during use.
