Microbial Air Sampler NMAS-202 is a highly efficient microorganism sampler and type of planktonic bacteria sampler in the microporous suction collector. It is designed on the principle of kinetic sampling. It can sample directly, and the velocity of the sampling port and the Cleanroom is consistent, so it can accurately reflect the microorganism concentration of the Cleanroom. In the sampling process, bio contaminated air is drawn through the small holes in the top plate. The system is designed to ensure biological efficiency by optimizing the striking velocity.
