The sma compressed air gas sampler is used for the automated collection of microorganisms in compressed air and gas lines.
The air is impacted onto the surface of growth media in a 90 100 mm petri dish or 55 60 mm contact plate.
Regulations protect the health and welfare of consumers.
Collect samples under gas pressure and gradual decompression prevents damage to microorganisms.
One such regulation is iso 8573 7 which provides guidelines to manufacturers for compressed air testing for microorganisms failure to use a proper validated sampling method to test compressed air can result in a false positive for microbial contamination.
Active air sampling requires the use of a microbiology air sampler to physically draw a known volume of air over or through a particle collection device and there are two main types.
