The laboratory fume hood plays an important role in the laboratory, because it is related to whether the natural environment in the laboratory is damaged, the physical health of laboratory employees, etc. So generally in the course of the experiment, some organic chemistry experiments are likely to cause some smoke and harmful gases to rise. Even if we do a good job of safety protection, it will still cause harm to the body. At the same time, there are often a lot of storage in the laboratory. The experimental equipment is also of high use value. If the durability of this harmful gas is obtained in the experimental room, it will also cause fatal damage to this equipment.

Therefore, the fume hood changes the natural environment of the laboratory during the application process, and also ensures that the natural environment of the experiment will not be harmed. Today's fume hoods are also relatively complete in design. During the experiment, we can choose the ventilation speed according to the size of the experiment, which can also reduce the cost of application and save energy. Secondly, the ventilation safety channel of the fume hood is usually all independent. In other words, in the application process, the independent safety channel can make it difficult for this harmful gas to flow back and other problems.

But when we use the fume hood, we must apply it, and measure and adjust the fume hood on time, so that the fume hood can operate under normal conditions. . Next, the durability of the fume hood is in contact with harmful gases, so we need to clean the fume hood on time during the application process, which can increase the service life of the fume hood.
