BioStage Single-Stage Viable Bioaerosol Impactor| Air-Met

Overview

The BioStage single-stage cascade impactor operates on the principle of inertial impaction and meets NIOSH and ACGIH recommendations for sampling indoor and outdoor air for viable microorganisms, including bacteria, and fungi.

Made of precision-tooled aluminium, the sampler contains a jet classification stage and base plate precision-threaded together for a positive seal and an inlet cone. The impactor stage contains precision-drilled holes. A sample pump draws air through the sampler where multiple jets of air direct airborne particles toward the surface of the agar collection medium.

Two models of the BioStage Impactor are available to accommodate two different flow rates.
