2.1.1 Product Concept
This cabinet defined as class II A2 type Microbiological Safety Cabinet, It totally meets thet
international standarded 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 HEPA can protect work materials, what’s
more, the polluted air flow become pure after processed by HEPA(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.
2.1.2 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.
