MAS-100 NT brochure

The MAS-100 microbial air monitoring systems are high-performance instruments which are based on the principle of the Andersen air sampler. Ambient air is aspirated through a perforated lid and impacted onto the surface of growth media in standard 90-100 mm Petri dishes or 55-60 mm contact plates.Microorganisms adhere to the culture media and, after an appropriate incubation period, the colonies are counted. The system measures the inflow of air and regulates it to a constant value of 100 liters/min. All MAS-100@ air samplers comply with the guidelines oflS0 14698 parts 1 and 2 using lCR culture media and fully meet the d50 requirements.
