The MAS-100 NT® microbial air monitoring systems are high performance, portable, battery operated instrument which are based on the principle of the Andersen air sampler. These compact yet sophisticated devices are the preferred choice for those demanding the highest quality in microbial air monitoring. A specified amount of air is aspirated through a 300-hole x 0.6 mm perforated lid and impacted onto the surface of growth media in standard 90-100 mm Petri dishes. All functions and parameters as well as the calibration procedure can be controlled using the MAS-100 NT® software or may be programmed directly on the unit. Alarms and samples are logged and the last 100 events recorded. These can be exported or printed at any time. Hardware and software have been developed according to GAMP4.

Application

The MAS-100 NT® air sampler is used for microbial monitoring of ambient air in controlled environments up to ISO 5 cleanrooms. Microbial air sampling devices are extensively used in Pharmaceutical and Personal care industries as well as Food, Beverage and Environmental applications. Additionally, a regulation for compounding pharmacies, USP797, that requires active air sampling in the level 5 and above areas.
