The Six-Stage Andersen Microbial Air Sampler is designed for accurate monitoring of airborne microorganisms in controlled environments such as cleanrooms, laboratories and biosafety facilities. The system reproduces the human respiratory tract structure using the Andersen impactor principle, allowing airborne microbial particles to be collected and classified according to aerodynamic size.

Based on aerodynamic sampling, airborne microorganisms are captured directly on the surface of a culture medium. After incubation, the samples are analyzed to determine the bacterial and fungal colony-forming units (CFU) per cubic meter of air, providing precise microbiological air quality assessment.
