MAS-100® Microbial Air Monitoring Systems


The MAS-100® Family – Leading Solutions in Air Monitoring

Request Information

Proven Technology for highly Accurate Microbial Air Sampling and Monitoring

All of the MAS-100® Microbial Air Monitoring systems are sieve impaction systems based on the Anderson impaction principle. Air is aspirated through a perforated lid. A radial fan, controlled by a flow sensor, accurately regulates air flow real time at 100 liters/min. The air is impacted onto the surface of growth media in a 90-100 mm Petri dish or 55-60 mm Contact Plate.


  • MAS-100® Microbial Air Samplers comply with the guidelines as specified in ISO 14698 part 1 and part 2
  • State-of-the-art mass flow sensor to ensure a constant air flow rate of 100 liters/min.
  • Continues regulation of air flow during sample collection
  • Automatic adjustment to different volume fills of Petri dishes, changes in air density and differences between individual perforated lids
