[Overview] Biosafety laboratories are used in microbial experiments involving the possibility of infection. The purpose of biosafety is to protect workers, collaborators, and laboratory support personnel from infection while studying various pathogenic microorganisms that pose a life-threatening risk to humans or animals, while protecting products and the environment from contamination. Clean indoor air infection is an important communication link that cannot be ignored. Even in a strict biological safety cabinet, it is difficult to avoid the escape of viral aerosols in the form of gas diffusion, and there are opportunities for positive animals to breathe. The air transmits viral molecules. In order to eliminate the harmful virus protection workers and environmental safety of clean indoor air, Orpheum Space Dry Mist Sterilization System is the most suitable choice.

Biosafety laboratory (biosafety laboratory), also known as biosafety containment for laboratories, is a biological experiment that can prevent or control the hazard of a pest that is manipulated through protective barriers and management measures to meet biosafety requirements. Room and animal laboratory.
Grading of biosafety laboratories
The first level is less harmful to humans, animals, plants or the environment, and does not have pathogenic factors for healthy adults, animals and plants.
Secondary to moderately hazardous or potentially dangerous virulence factors to humans, animals, plants or the environment, without causing serious harm to healthy adults, animals and the environment. There are effective preventive and therapeutic measures.
Tertiary is highly dangerous to humans, animals, plants or the environment. It is mainly caused by aerosols that cause serious or even fatal diseases, or pathogenic factors that are highly harmful to animals, plants and the environment. There are usually preventive and therapeutic measures.
Level 4 is highly dangerous to humans, animals, plants or the environment, and transmits or transmits through the aerosol route unknown or unknown, dangerous pathogenic factors. There are no preventive and therapeutic measures.
It can be seen from the above that especially the p3 and p4 laboratories must strictly control the cleanliness of the air. The space dry mist sterilization system can effectively kill viruses and harmful microorganisms in the air in the laboratory.
Its principle of action: the spraying process is completed by spreading dry mist to the area that needs to be sterilized. When the average diameter of the droplets is less than 10 microns, the ejected mist can be said to be "dry"; the small droplets will bounce off the wall and will not rupture and adhere to the surface. All conditions are established to effectively move the sterilant in a gasified form to a designated area. This form of characteristics determines that they can be moved to areas that are difficult to reach at ordinary times.
Dry fog has the following properties :
1. Dry mist droplets carry out irregular motion (Brown motion principle) and will not settle;
2. Dry mist droplets do not aggregate together to produce large droplets;
3. The dry mist will rebound after contact with the surface without rupturing and moistening the surface;
Advantages of dry mist sterilization system:
1. The sterilizing agent can be controlled to be sprayed in the form of dry mist. The size of the dry mist particles is controlled at a precise and consistent level, which reduces the risk of condensing liquid and ensures the penetration and disinfection effect on the more complicated and difficult to reach.
2, can effectively reach all areas of the clean room.
3, efficient sterilization, can achieve the killing effect of 6 logs of Bacillus subtilis
4, rapid sterilization, only 2 to 3 hours to complete the entire sterilization process
5, low corrosivity, no toxicity, no residue will not pollute the environment
6, complete verification data, residue verification, complete compatibility verification
7, flexible use, simple operation, small size and easy to move
