Balance Enclosures provide user protection by keeping powders, particulates and fumes contained during weighing procedures. Balance Enclosures may be ducted to the outside or connected to a HEPA and/or carbon filtered exhaust back into the laboratory.
Ductless Fume Hoods are enclosures that pass contaminated air through a filter(s) before returning air to the room. Use for locations where outside ventilation can not be achieved. 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.
Ducted Fume Hoods have ventilation to 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.
Biological Safety Cabinets provide effective containment for working with human pathogens. BSC cabinets have three classes as sedignated by the National Sanitation FoundationClass I, II, and III, with some sub class levels.
BSC Class I have an un-recirculated airflow away from the lab worker that, after going through a HEPA filter, is vented into the room. They provide the lab worker medium protection but do not protect the samples in the bacinet from contamination.
BCS Class II should be used if a lab worker is using microorganisms in containment levels 2, 3,bs. These cabinets are divided into two typesA and B, determined by construction, airflow velocities, patterns, and exhaust systems. They protect the lab worker, samples, and the external environment.
BCS Class III have both HEPA filtered supply and exhaust air and are totally gas tight and enclosed. Tests are performed while using long sleeved gloves. The cabinet is under negative pressure of at least 120 Pa while the exterior exhaust system maintains airflow. This protects the lab worker, samples, and the external environment.
PCR Enclosures are designed specifically to privide a Class 5 work space for PCR experiments by moving HEPA filtered air downward. PCR enclosures are unique in that they have a UV light that eliminates DNA and RNA contaminates
Extractor Systems provide localized ventilation at the contaminant source. Extractor arms can be easily positioned to remove fumes or air-borne particulates. Often used when the fume source can not 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.
