MAS-100 Iso MH

MBV MAS-100 Iso MH air sampler

Principle: Viable air sampler based on mass flow measurement

Automation: Yes

Approvals: Meets ISO 14698-1 and EN 17141 in ISO Class 5 and GMP Grade A

Suitability: Microbial air monitoring in isolators and RABS

Capital equipment required: Nutrient plate


The air sampler MAS-100 Iso MH is used for microbiological monitoring of air in isolators or RABS. It can be equipped with 1 - 4 collecting positions. The sampling heads with the culture medium plates are located in the housing, while the control unit with electronics and moving parts is located outside the cleanroom and sucks the air through a tube/hose system. The instrument is designed for maximum protection of the product and the environment and can be controlled fully automatically via various data interfaces.

Key Points:
  • Developed according to GAMP 5, fully validated according to ISO 14698 and EN 17141
  • Applicable in environments of ISO 14644 purity classes 5, GMP Grade A
  • 1 - 4 sampling points with a single space-saving base unit
  • No moving components (e.g. blower) in the enclosure
  • Sequentially switched double valve protects the containment from contamination
  • If necessary, the base unit can be replaced during operation as one valve is still closed.
  • All components in the enclosure are made exclusively of stainless steel
  • Precision seal between perforated cover and collection head, without sealing ring, facilitates cleaning and disinfection
  • Automatically startable hydrogen peroxide disinfection cycle
  • Installation of environmental protection filters possible for the processing of highly active substances
  • Tested with piping from collecting head to electronic unit up to 50m length
  • Compatible with many different nutrient plates e.g. 90mm Petri dishes, Growth Direct™ consumables
  • Interchangeable and sterilizable perforated cover 
  • Integrated mass flow sensor with temperature and pressure compensation for ambient air sampling
  • Airflow of each collecting position can be independently calibrated with digital anemometer
