fume hood is an important part of laboratory equipment. In a scientific laboratory environment, good ventilation is very important to create a clean laboratory environment and ensure scientific, reliable and safe experimental conditions. Therefore, when cleaning the vents of the fume hood, we need to pay attention to the following points:

       1. In order to maintain a good appearance, please follow good maintenance procedures. To ensure a safe working environment, please promptly clean up any accidentally dumped chemical liquids. Do not use wax on the surface.

       2. Please clean it regularly and use bright oil products (no wax) for maintenance. Do not sand seams and scratches. In the case of sudden changes in temperature, damage can occur, for example liquid nitrogen or dry ice can cause damage to the surface, and improper use of these substances can cause the material to break or sink.

       3. Please do not leave this material in an environment where the temperature exceeds 135°C for a long time. Do not expose this material to open flames, molten metal, metal fires, or direct sunlight, nor should it be used as a shredding surface.

       4, The flame of a gas lamp or alcohol lamp will damage the surface of the fume hood, so a gas lamp or alcohol lamp should be used on a tripod.

       5. It is recommended to use warm water, acetone or mild detergent to clean the surface of the corrosion-resistant plate (for hand washing or dishwashing). Do not choose detergents containing strong acids to avoid damaging the surface. For stubborn stains, hypochlorite can be dropped on the surface of the contaminated corrosion-resistant steel plate and cleaned with clean water.
