AS1 is an air sampling meter used to assess microbiological pollution and monitor hygiene. Designed for use in hospitals, clean rooms and food and beverage, cosmetics and pharmaceutical production facilities, the AS1 air sampler meets the latest requirements for devices used for airborne microbial analysis.

The AS1 air sampling device uses the aerosol impaction principle or Andersen collision principle when taking measurements. When samples are taken, the air particles enter through the surface of the meter. The particles then hit the surface of the agar medium in the standard Petri dish placed inside the autoclavable collector head. The medium maintains the activity of the bacteria, ensuring the best conditions for incubation and counting. Upon conclusion of the incubation period, the number of microorganisms can be determined.
