A fundamental aspect of cleanrooms and critical zones is to achieve lowest concentrations of airborne particles by reducing ther introduction and generation. Measurement for this purpose must be accurate as well as reliable, and must not interfere with the zone protection.

The MD8 air samplers, MD8 Airscan and the portable AirPort MD8, are designed to detect smallest viruses and microorganism in the air by using the unique Gelatine Membrane Filters (GMF) and BACTairTM agar plates. Air sampling in critical areas can be performed isokinetically with MD8 Airscan.
