Merck Air Sampling

All MAS-100® Microbial Air Monitor- ing Systems are sieve impaction systems based on the Anderson impac- tion principle, accepted and proven worldwide. Air is aspirated through a perforated lid. A radial fan, controlled by a flow sensor, accurately regulates air flow real time at 100 litres/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 new ISO 14698 part1 and part 2.
