MAS‑100 VF®

Volume flow measurement

The portable MAS‑100 VF® is designed to efficiently monitor air microbiology in cleanrooms and other controlled environments in which microbiological contamination has a direct impact on product quality, shelf life and deterioration. Like all other MAS air samplers, the MAS‑100 VF® is based on the Andersen impaction principle. It offers the same recovery rate as the MAS‑100 NT® model, but is much lighter and can be configured and programmed using standard browsers. It uses standard 90 to 100 mm Petri dishes and boasts ease of use, a compact, handy design and an attractive price.
