Biosafety Cabinets are designed to protect the operator, the laboratory environment, and laboratory materials from exposure to infectious aerosols and spills that may be generated during the handling of infectious laboratory materials such as viruses, pathogens, primary cultures, bacteriophages, and diagnostic specimens.

Ordinary Class II Type A2 BSC

The Ordinary Class II A2 BSC draws airflow through the fan system into the front intake grille and through the airflow channel at the back to the upper level, where 30% of the airflow is filtered through the outgoing HEPA filter and discharged, and 70% is recirculated through the upper HEPA filter, providing downward, clean vertical airflow that protects the operator, samples, and the environment. Class II A2 BSC with H14 HEPA filter can effectively filter 99.995% of 0.3μm particles.

Dual Filtration System Class II A2 BSC

Mars Pro 1200 is built based on the common Class II, Type A2 BSC, with one additional H14 HEPA filter under the operating worktop. Enter the lower filter under the operating worktop for primary filtration, and then pass through the upper HEPA filter for secondary filtration. 2 sets of triple HEPA filter systems can effectively filter 99.99995% of 0.3μm particles. It can be used for microbiology and virology research, especially on infectious pathogens; stem cell/gene therapy; research on cytotoxic substances, etc.

(The airflow paths of the two filtration systems are shown as follows)

Unique Microbial Capture Trap

• The main HEPA filter under the worktop has 4 sets of 12 built-in "microbial traps", inside which the pathogenic microorganisms can be captured and well-kept, until later disposal and exchange of filters with no prior decontamination being required;

• Air pathways and channels, filters, and fans remain contamination-free.;

• Safe to replace filter whilst the cabinet is operating – able to seal and remove the used filters under the worktop in a negative pressure environment.
