Microbial Air Sampler NMAS-201

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.
