Design concept:

1, to control indoor air bacteria or microbes, ensure that the bacteria or other microorganisms are not the carrier of survival; at the same time, avoid the dust particles from the outside pollution, and affect the accuracy of the experimental results.

2. The layout of the laboratory is divided into clean area, semi polluted area and polluted area according to the safety requirements. The special channel is set up by people and objects, the necessary buffer rooms are set up, and the measures of one isolation and two isolation are adopted to prevent the cross pollution effectively. The biosafety laboratory is always in a relatively sealed environment, preventing the exotecta of microbes, easy to clean and disinfect the laboratory, and avoid the destruction of the laboratory environment.
