Ordinary clean laboratory
Experiments conducted in ordinary clean laboratories are not infectious, but require that the environment does not adversely affect the experiment itself. Therefore, there are no protective facilities in the laboratory, and the cleanliness must meet the experimental requirements, so laboratory disinfection is necessary.
The biosafety laboratory is a biological laboratory with first-level protection facilities and second-level protection. All scientific experiments in the fields of microbiology, biomedicine, functional experiments and genetic recombination require a biosafety laboratory.
