MAS‑100 Iso NT®

One sampling position with display

The MAS‑100 Iso NT® 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 one stainless steel sampling head for standard 90 to 100 mm Petri dishes collects samples in the containment zone. The unique double-valve protection concept keeps contaminants out of the containment zone and prevents potential loss of production batches. The MAS‑100 Iso NT® also has an integrated pump with flow monitoring for automatic in-line decontamination of the sampling head and aspiration tube. Thanks to fully automatic calibration, the device guarantees maximum efficiency and accuracy.
