The laboratory fume hood is an indispensable equipment in the laboratory, but we must pay attention to safety when using it. Before the test starts, we must ensure that the fume hood is in the running state before starting the test. At least 5 minutes to ensure the removal of gas remaining in the pipeline. Ensure that no equipment is placed within 150mm of the equipment during the test to ensure good air circulation. The front window should be closed during use.
In addition to the above security issues, there are some issues that must be taken into account when using them.
1. In our experiments, sometimes the glass window accidentally falls, causing accidental injuries to many people. In order to avoid such accidents, in recent years, the fume hood is equipped with a window anti-drop pin, so that even if there is an accidental fall. The anti-drop pin will also catch.
2. The glass window of the fume hood is made of tempered glass. When the glass accidentally explodes or crashes, there is no personal injury.
3, the appearance of the water valve, gas nozzle valve peripheral remote handle, is safer and more reliable than direct manual operation.
4. In order to eliminate harmful gases more effectively, the fume hood adopts a single-slot exhaust structure, which provides a guarantee for better testing.
5, the ventilation shell is made of metal material, so it has non-combustible effect, and the inner cavity also has non-combustible anti-double special board, which makes us safer and safer when using the equipment. The table top is made of solid physico-chemical board or stainless steel board. The material has the effects of preventing acid and alkali, heat and flame retardant.
