Fume hoods are mainly used in industries with risks of chemical, biological, or dust pollution. Their core function is to discharge harmful gases, protect the safety of operators, and maintain a clean experimental environment.
In scientific research and education, fume hoods are essential for a wide range of laboratory procedures, protecting users during chemical manipulations.
University laboratories: Teaching experiments for majors such as chemistry, biology, and environmental science, including reagent mixing and sample digestion.
Research institutes: Activities like advanced material synthesis, pharmaceutical development, and microbial culturing involve hazardous solvents or toxic agents.
In the testing of food, water quality, and soil, the process involves the pretreatment of samples (such as extraction and digestion) that generates harmful gases.
2. Pharmaceutical and chemical industries
In the production and research and development processes of this field, a large amount of harmful gases is continuously generated, which requires higher corrosion resistance and exhaust efficiency from fume hoods.
Pharmaceutical enterprises: In drug synthesis, active pharmaceutical ingredient production, and formulation research and development, organic vapors and volatile substances of chemical intermediates need to be discharged.
Chemical enterprises: Facilities for fine chemical and novel material synthesis, handling corrosive gases and toxic solvents such as methanol and acetone.
Pesticide production: Research and development, and production of insecticides and herbicides, to prevent highly toxic and highly volatile substances from endangering operators.
3. Medical and health care fields
It mainly serves clinical testing and biosafety-related operations, and needs to take into account both anti-corrosion and biological protection functions.
Hospital laboratory: Chemical analysis and microbiological testing of clinical samples (blood, urine) to prevent aerosol diffusion.
The Centers for Disease Control and Prevention: For infectious disease testing and virus research (such as influenza virus and COVID-19 testing), biosafety fume hoods are required.
Pathology Department: Fixation and staining of tissue specimens, and removal of volatile fixatives such as formaldehyde and xylene.
4. Electronics and semiconductor industry
This field has extremely high requirements for environmental cleanliness. Fume hoods need to simultaneously meet the demands of exhaust and dust pollution prevention.
Semiconductor factory: In the photolithography and etching processes of chip manufacturing, volatile substances of photoresist and acidic gases (such as hydrogen fluoride) are discharged.
Electronic component production: PCB circuit board manufacturing, electronic material research and development, handling flux volatiles and heavy metal vapors (such as lead and mercury).
5. Other special industries
Food industry: Scenarios for food additive research and development, microbiological testing laboratories, or handling food disinfectants (such as hydrogen peroxide).
Metallurgy and materials industry: Corrosion testing of metal materials, gas emissions after high-temperature smelting, such as treatment of metal oxide dust, acidic testing gases.
Environmental protection industry: Small-scale experiments on waste gas and wastewater treatment processes, simulating the collection of harmful gases produced during the degradation of pollutants.
