Protect workers from fumes and vapors with appropriate ventilation. Find a listing below of various types of fume hoods and enclosures to enhance lab safety.
Ducted Fume Hoods
Ventilation to the outside provides the most rigorous user protection, particularly for chemically dangerous fumes. Many employ “by-pass” designs, which enable consistent airflows in the enclosure for various sash positions. Low airflow designs provide user protection while minimizing energy costs.
Biosafety and PCR Enclosures
Hybrid models enable handling of sensitive materials while protecting the user. Airflow is HEPA filtered entering the cabinet and again upon exit, or discharged to the outside. Applications include manipulating dangerous but sensitive biological materials, e.g. Class II, Type A2 cabinets.
Provide localized ventilation at the contaminant source. Extractor arms can be easily positioned to remove fumes or airborne particulates. Often used when the fume source cannot be readily moved to a conventional hood or when fumes are innocuous, e.g. bad-smelling without being chemically dangerous. May vent to outside or recirculate into the room through a filter.
These hoods enhance fume removal by partially surrounding the fume source. Some models direct forced airflow to afford further protection. Low-flow ventilation systems enable delicate operations, e.g. weighing while maintaining personal protection. May vent to outside or recirculate into the room through a filter.
Ductless Fume Hoods
These enclosures pass contaminated air through a filter(s) before returning air to the room. Use for locations where outside ventilation cannot be achieved. These can eliminate very high percentages of particulates and biological hazards. Select airborne chemical levels can be reduced to safe levels as verified with monitoring protocols.
