Biologic Safety Cabinet
Scope of Application:
Biological safety cabinet is a kind of negative pressure device
widely used in microbiology, biomedicine, gene recombination,
animal experiments, biological products, other fields of scientific
research, teaching and clinical examination. It adopts the advanced
air purification technology and vacuumbox design to protect the
environment, people and samples, which is the basic laboratory
bio-safety protection equipment used in laboratories with level-one
of bio-safety . When air outlet is connected with outside, this
equipment can also be applied for biology experiments with trace
volatile toxic chemicals and limited radionuclides as additives.
Structure Characteristics:
•Composed of safety box, framework, fan, high efficiency air filter
and control system.
•Material: Safety box is made of high qualified cold-rolled plate
and workroom is made of SUS 304 stainless steel.
•Air outlet is bilayer structure between workroom and outer shell.
•Air circulating system made of imported fan, high efficiency
filter, negative pressure systemair passage and exhaust pipe.
•Microprocessor control system.
A2: Built-in centrifugal fan, mixed air from the room and the
cabinet go through the static pressure box, about 30% of the mixed
air is exhausted from the high efficiency filter and other 70% is
recycled in the work room from down flow filter
B2: Air inhalation from the top of the cabinet, air go through the
high efficiency filter from the static pressure box to the work
room by the centrifugal fan, the down flow air along with the air
inhaled from the operation room is 100% exhausted to the outdoor
space through outer air duct and high efficiency air filter by
central exhaust system or external exhaust fan
