Microbial Air Sampler NMAS-200
Microbial Air Sampler NMAS-200 is a high-efficiency multi-hole inhaled air sampler. It is designed in regard to the principle of isokinetic sampling by the two theories of the particles-impact and equal-flow-sampling. When sampling port is 397 meshes with a diameter of 0.7mm Micropore, which reduces bacterial overlap and microbial counting errors, planktonic bacteria with air highly-speed thrill through a ventage, and then they impinge on the surface of the agar in the culture medium. When the microbes are cultivated, they will be dynamic-hydrated and high-speed flowing because of which we can procure results quickly.
