Air Sampler - Model MAS-100 - EM Science Microbiological

The MAS-100 is a high-performance instrument that is based on the principle of the Andersen air sampler , which aspirates air through a perforated plate. The resultant airflow is directed onto a standard agar poured plate. After the collection cycle, the Petri dish is incubated and the colonies are counted. The MAS-100 operates with a high-performance suction device, and the aspirated volume is continuously monitored. The system measures the inflow of air and regulates the aspirated volume to a constant value of 100 liters per minute. The MAS-100 automatically regulates this volume if there are external factors preventing a steady flow of air, or if overfilled Petri dishes are blocking or impeding flow. For measurement in pharmaceutical industry the recommended sampling volume – according to international guidelines – should be 1000 liters.
