The MAS-100 NT® and MAS-100 NT Ex® portable microbial air samplers are the industry standard for use in cleanrooms and critical environments. The MAS-100 NT® and MAS-100 NT Ex® systems have high collection efficiency for precise and reproducible measurements.
The MAS-100 NT Ex® shares all of the same functions of the MAS-100 NT® sampler but is specially designed for use in explosion proof areas. The MAS-100 NT Ex® system has received ATEX Conformity and can be used in zone 2 and gas groups IIA, IIB and IIC in temperature classes T1 to T4.
Viable air samplers are used for quantitative determination of airborne contamination in cleanrooms and isolators. To maintain the cleanliness of the environment, the air flow should neither disturb the unidirectional air flow nor pose a contamination risk to the environment.
As portable air samplers are sometimes moved and used in various environments with different levels of microbial contamination, there might be a risk of cross-contamination from higher to low contaminated environments.
The MAS-100 NT® is specified for use in ISO Class 5/ GMP Grade A environments and is equipped with a brushless motor which generates a minimal quantity of particles, so that no filter is required even for GMP Grade A usage. If instruments are used in different cleanroom classes, there is a minor risk that particles may be carried over inside an instrument. In this case, a HEPA H13 exhaust air particle filter can be mounted to give you peace of mind.
To prevent any potential transfer of particles from inside the instrument, an air outlet filter adapter was developed to add a HEPA H13 filter to the exhaust. The filter has no significant influence on the airflow calibration and therefore on the microbial sampling efficiency. In addition, stressing the filter for a simulated year of heavy usage in an uncontrolled environment does not reduce the filtration efficiency and won’t clog the filter.

The MAS-100 Atmos® makes the detection of microorganisms in compressed gases easy, safe and accurate. It is designed for testing the four pre-defined gas types air, nitrogen, carbon dioxide and argon at a pressure range of 1.2 to 7 bar abs. It is the only instrument impaction microorganisms under pressure to avoid probable lethal damage by fast decompression.
SIMPLE thanks to fully automated steps, four predefined gas programs, and an easy-to-use touch screen interface. Plus, the instrument is compact, portable and battery operated.
SAFE because we’ve automated the regulation of the flow rate for the selectable gas types at current pressure ranges, as well as the decompression cycle of pressurized gases and have minimized handling errors.
COMPLIANT thanks to 21 CFR Part 11 compliant user management, secure user login, and fully traceable working steps.
EFFICIENT because of impacting the microorganisms under pressure to avoid the risk of injury caused by rapid decompression. The impaction speed is identical to the MAS-100 NT® air sampler
