Avoiding Cross Contamination during Viable Active Air Sampling in Clean Rooms


Viable air samplers are used for quantitative determination of airborne contamination in cleanrooms for aseptic manufacturing. To maintain the cleanliness of the environment, the exhaust air flow should neither disturb the unidirectional air flow nor pose a contamination risk to the environment.

Our experts cover the essential points of air sampling units for use in your high-grade cleanrooms, along with requirements for prevention of cross-contamination.

Key topics covered in the webinar:

  • Instrument selection tips and selection criteria for air samplers used in cleanrooms
    • Working environments & regulatory requirements
    • Measurements to prevent cross-contamination
    • Validation of an exhaust filter
