Microbial indicators (such as Staphylococcus aureus suspension) are pumped to the spray port of the aerosol generator by a peristaltic pump, and the air source is also delivered to the spray port of the aerosol generator, so that the microbial suspension is atomized in the aerosol generator to produce bacterial aerosols. Bacteria are sampled through a biological sampler followed by culture. Finally, the filtration efficiency of the mask is calculated according to the bacterial aerosol concentration before and after the mask filtration.
Mask bacteria filtration detection
Mask bacteria filtration detection equipment has a built-in peristaltic pump for transferring bacterial suspension to the aerosol chamber. The suspension meets the high-pressure gas at the spray port of the aerosol chamber to produce an aerosol. By comparing the concentration of bacterial aerosols before and after filtration, it was used to detect whether the bacterial filtration efficiency of the mask met the relevant standards.
During the transfer of the bacterial suspension, the activity of the bacteria is not destroyed
Peristaltic pump flow adjustable, flow range: 0.006~3.0 (ml/min)
Flow accuracy: above ±2.5%
Recommended model: BT100-2J
