Air Samplers (active air sampling) – Air samplers draw in predetermined volumes of air. The air is drawn over a sterile media plate, which is later incubated to reveal the number of viable organisms per cubic feet or liter. Currently agar impaction is the method of choice throughout the industries. Using a specially designed, and calibrated piece of equipment which holds the media plate under a perforated lid and draws in a known amount of air one can accurately measure the amount of viable bacteria within the air.
