Microbial Air Sampler NMAS-201 is designed by unibody shell, solid and durable sampler device with a high sampling speed and accuracy. The sampler has many tiny holes through which the air is aspirated and also that reduces the puffball superposition and error of animalcule count. Programmable, sampling quantity can be set from 0.1 to 2.0 steres that in turn saves sampling time and other parameters. The sampling mouth is 397 meshes, the diameter is 0.7mm micropore resulting in the reduced bacterial overlap and microbial count error.

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.
