The purpose ofbiological safety cabinetsis to provide protection
to personnel, environment and products. When the operator does
an experiment with bacteria, strains and infectious materials,
the biological safety cabinets could protect the operator from
contagious aerosols. The biological safety cabinet is the necessary
equipment for labs of microbiology, biomedical, gene recombination,
animal experiment and biological
productsspecially theplaceswhere the operators need to be
protected, such as medical service，pharmacy and scientific research for
culture of bacteria, these situations all need dust-free and
sterile safe working environment.
Biological Safety Cabinet is a
negative pressure filter ventilation cabinet to protect personnel,
products and environment. The inflow air can protect the personnel
and vertical down-flow air is filtrated by HEPA/ULPA to protect
products. Contaminative air is filtrated by HEPA (ULPA) to protect
environment. When it is used for microbiological experiment of
minim volatility toxic chemical or trace radionuclide, it should be
equipped with suitable exhaust hood.
