Fume hood main functionis is exhaust function. In the chemical laboratory, various harmful gases, odors, moisture, and flammable, explosive, and corrosive substances are generated during the experimental operation. It is safe to prevent the pollutants in the experiment from spreading to the laboratory.
Biosafety cabinets are widely used in health care, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring, and various biological laboratories. They are an important foundation for ensuring biosafety and environmental safety. Fume hoods and clean benches are not biosafety cabinets and should not be used in experiments or production processes involving microbial materials.
Laboratory ventilation is an integral part of laboratory design. The most important function of the fume hood is the exhaust function. In the chemical laboratory, all kinds of harmful gases, odors, moisture and flammable, explosive and corrosive substances are generated during the experimental operation, in order to protect the safety of users. To prevent the spread of pollutants in the laboratory to the laboratory, use a fume hood near the source of pollution.
Fume hoods are ventilated enclosures that remove hazardous chemical fumes and volatile vapors from a laboratory, providing only personnel protection. Biosafety cabinets utilize HEPA filters to provide environmental, personnel and/or product protection.
Depending on your application, they can recirculate or exhaust filtered air and are suitable for dealing with harmful particles such as bacteria and viruses.
