The air sampler MAS-100 Iso NT is used for microbiological monitoring of air in isolators and RABS. The collection head with the culture medium plate is located in the housing, while the control unit with electronics and all moving parts is located outside the cleanroom and sucks the air through a tube/hose system. The system is designed for maximum product and environmental protection and can be controlled either manually, via the device display, or fully automatically, via connection to a user interface using various data interfaces.
