The MAS-100 Iso® NT is specially designed for monitoring microbiological contamination of the air in aseptic production areas and isolators with the rigorous requirements of the pharmaceutical industry in mind.
A unique safety concept permits the installation of various sampling heads for standard 90-100 mm Petri dishes at the critical control points while all electronic and moving parts remain outside the critical zone. The MAS-100 Iso® NT has an additional internal pump with flow control for automatic decontamination of the sampling head and the aspiration tube. The MAS-100 Iso® NT is built according to GAMP 4 and corresponds to the ISO 14698 norm. It is a completely validated system designed for the highest demands.
Benefits:
- Integrated mass-flow sensor
- Software in several languages
- In-line decontamination
- IP 54 and IP66 models available
- 3/4 inch Tri-Clamp connection
- Andersen impaction principle
Growth properties of dehydrated ICR settle plates used in passive air monitoring
Settle plates provide continuous environmental monitoring of microorganisms in the volume of collected air. The formulation of the chosen culture media should promote the growth of a wide range of microorganisms. This application note investigates the growth properties of ICR settle plates with and without neutralizers. Using this method, the detection of environmental microorganisms could be compared between pre-dried and fresh plates without re-humidifying the dehydrated plates.
Air outlet particle filter for viable air sampler MAS-100 NT
The determination of airborne contamination requires viable air samplers where the air flow should neither disturb the unidirectional air flow nor pose a contamination risk to the environment. Using the MAS-100 NT® air sampler, this scientific poster investigates the need for filtration of the exhaust air, especially when air sampling with the same instrument is performed in environments with various contamination rates.
