Active Air Monitoring
There is an increasing need for effective air monitoring in all areas where airborne microorganisms may contaminate or affect industrial products and processes. Air monitoring is therefore particularly important for all companies that manufacture in clean room areas with filtered air. Active air monitoring with settle plates or contact plates requires the use of a microbiological air sampler to physically draw a certain, pre-determined volume of air and pass it over the agar. The plate is then removed from the air sampler and directly incubated, allowing visible colonies to develop and subsequently be counted. The number of visible colonies gives an estimate of the number of colony forming units in the sampled air.
Settle plates from Merck are ideally suited for use with the MAS-100® range of microbial air monitoring systems. These are capable of handling high flow rates and the large sample volumes necessary to monitor air quality in highly critical clean rooms where the number of microbes present is likely to be very low.
