4.1.1 Product Concept
This cabinet defined as class II A2 type Microbiological Safety Cabinet, It totally meets the
European standard for biological cabinet EN 12469:2000 standard. Microbiological Safety Cabinet is
a kind of negative pressure filtration system for protecting operator, the laboratory environment and
work materials, the front opening which air flow inward have protection function for operator, the
filtered laminar flow generated by vertical ULPA can protect work materials, what’s more, the
polluted air flow become pure after processed by ULPA filter. When it’s used in microbiology
experiment environment filled with volatile or toxic chemical and radionuclide, suitable exhaust
hood in function have to be linked.
4.1.2 Application Range
Microbiological Safety Cabinet is necessary equipment in the laboratory in the search of
microbiology, biomedical, DNA recombinant, animal experiment, and biological products, especially
in the occasion that operator need to adopt protective measure, such as medical and health, pharmacy,
medical research. Our equipment provides a safety working environment which don’t have bacterial
and dust in the process of bacterial culture.
