Description
AIS Microbial Air Samplers are used wherever there is a need to monitor and control microbial contamination (e.g. clean rooms). They are widely deployed in the pharmaceutical, dairy and fermentation industries.
Features
- • Constant sampling speed
- • User-friendly interface
- • Adjustable sampling head
- • Data traceability
- • Automatic air flow compensation (AIS-3 only)
- • Long battery life
- • 95% sampling efficiency
Measuring Principle
The AIS Microbial Air Samplers work according to the Andersen Collision principle. Air is aspirated (at a fixed speed for variable times) through small holes in the instrument’s head. The resulting laminar air flow is directed onto the surface of an agar plate. At the end of the sampling cycle the plate is removed and incubated. The visible colonies are then counted to assess the level of contamination.
