MAS‑100 Iso MH®

One to four sampling positions

Der MAS‑100 Iso MH® dient der mikrobiologischen The MAS‑100 Iso MH® is designed to monitor air microbiology in isolators and RABS. Like all other MAS-100 air samplers, it’s based on the Andersen impaction principle. All electronic and moving parts are located outside the critical zone, whilst up to four sampling heads for standard 90 to 100 mm Petri dishes collect samples in the containment zone. The unique double-valve protection concept keeps contaminants out of the containment zone and prevents loss of production batches. The MAS‑100 Iso MH® also has an integrated pump with flow monitoring for automatic in-line decontamination of the sampling heads and aspiration tubes. Thanks to fully automatic calibration, the device guarantees maximum efficiency and accuracy.
