15, gas fumigation is often used for disinfection of biological laboratories, especially for disinfection of rooms and instruments. Right?

The gas fumigation disinfection method refers to the treatment method of disinfecting or sterilizing articles with disinfectant gas in special disinfection cabinets and bags, which is suitable for the disinfection and sterilization of articles that are afraid of humidity, heat and corrosion, such as medical education, cloth netting, medical instruments, clothes, books, leather products and precision instruments.

Formaldehyde fumigation disinfection is not suitable for the disinfection of packaging items and precision instruments that are afraid of corrosion.

The commonly used air fumigation disinfection method generally uses the chemical reaction between formaldehyde and potassium permanganate to produce a large amount of formaldehyde gas. Before fumigation and disinfection, in order to improve the disinfection quality, it is necessary to clean the duck house, keep a certain temperature, preferably above 20℃, and close the doors and windows.

Extended data:

Distillation bottles can be divided into reduced pressure and normal pressure. The atmospheric distillation bottle also has branches at the upper, middle and lower parts of the bottleneck. For the distillation of liquid with higher boiling point, the distillation bottle with lower boiling point is selected, and the lower boiling point flows in the upper part. The branch pipe is located at the bottleneck and is usually used to distill liquids with ordinary boiling point.

The number of dust particles greater than or equal to 0.5μm is more than 352000 /m3(352 /L) to less than or equal to 352000 /m3(3520 /L), and the number of dust particles greater than or equal to 3μm is more than 3000 /m3(3 /L) to less than or equal to 30000 /m3(30 /L).
