Highest collection efficiency and safety in isolators and rabs with up to four sampling points.

• Precise, reproducible measurements and outstanding user flexibility
• Excellent collection efficiency
• Fully automatic calibration

The microbial air sampler MAS-100 Iso MH is used for microbial monitoring of air in isolators and RABS. It can be configured with one to four sampling heads. The sampling heads with the nutrient plates are located in the containment, while the control unit with electronics and all moving parts is located outside the enclosure and aspirates the air through a pipe/tube system. The system is designed for maximum protection of the product and the environment and can be controlled fully automatically via various data interfaces.
