MICROBIAL AIR SAMPLER MAS-100 NT Ex®
HIGHEST AIR SAMPLING COLLECTION EFFICIENCY AND SAFETY IN EXPLOSIVE ENVIRONMENTS
The MAS-100 NT Ex is the explosion-proof version of the world's best-selling air sampler and the premium version of the portable MAS-100 instruments. It is used for microbiological monitoring of air in rooms with increased explosion hazards for example due to solvents or gases. Equipped with a high-precision mass flow sensor it stands for highest safety and is therefore mainly used in sensitive areas and cleanrooms.
- Explosion protection according to the ATEX product directive 2014/34/EU (ATEX 114).
- Developed according to GAMP 5, fully validated according to ISO 14698 and EN 17141
- Can be used in ISO 14644-1 cleanroom class 5/GMP Grade A without air outlet filter
- Disinfectable with vaporized and gaseous hydrogen peroxide and many industry-standard disinfectants
- Perforated lids are autoclavable and interchangeable between instruments
- Compatible with different nutrient plates, e.g. ready-to-use 90mm standard-, 55mm contact- or Growth Direct® plates
- Additional safety through integration of a HEPA air outlet filter that can also be retrofitted and replaced independently
- Integrated mass flow sensor with temperature and pressure compensation for environment-independent air sampling
- Precision seal between perforated lid and sampling head without sealing ring facilitates cleaning and disinfection
- Rotatable sampling head for air sampling with horizontal air flow

Tailored to the application
OTHER VERSIONS OF THE MAS-100 NT MODEL
In order to meet the requirements of individual applications even more specifically, various special versions of this popular environmental monitoring instrument have been developed in addition to the standard version of the MAS-100 NT. Our expert Andy Zingre explains in 3 minutes how these versions differ and which applications the special versions of the MAS-100 NT are tailored to.
MAS-100 NT Ex HEPA
Specialized in microbiological air monitoring in potentially explosive environments of various cleanroom classes with zone changes: the MAS-100 NT Ex with a factory-installed HEPA H13 air outlet filter to protect against carryover of contamination.
BASIC VERSION MAS-100 NT
World's best-selling air sampler and base model of the MAS-100 NT Ex. In distinction to the MAS-100 NT Ex, the MAS-100 NT is designed for microbiological air monitoring in non-hazardous environments.
MAS-100 NT HEPA
Specialized in microbiological air monitoring in various cleanroom classes with zone change: the MAS-100 NT with a factory-installed HEPA H13 air outlet filter to protect against carry-over of contamination.
OPTION: MAS-100 NT Ex WITH AIR OUTLET FILTER
The MAS-100 NT Ex microbial air sampler is specified for use in cleanroom class 5 according to ISO 14644-1 (GMP grade A). The use of high quality and low particle components means that no additional air outlet filter is required. However, a filter can be advantageous in order to eliminate the carry-over of contamination when using the instrument in different cleanroom classes with zone changes.
The MAS-100 NT Ex is therefore also available as a version with a built-in HEPA H13 air outlet filter. It is also possible to retrofit a MAS-100 NT with a HEPA H13 filter kit. The supplied transport case is prepared to hold the instrument with or without filter module.
AIR FLOW SENSOR FOR ENVIRONMENT - INDEPENDENT AIR COLLECTION
A calibrated mass flow sensor in the MAS-100 NT Ex microbial air sampler ensures that always exactly the same amount of air is collected, regardless of ambient pressure and temperature. The standardisation of the air flow allows comparison between different locations and environmental conditions and has established itself as the gold standard in active air samplers.
The flow sensor is calibrated with a MAS-100 Regulus digital anemometer which is certified in our ISO 17025 accredited calibration laboratory. This ensures complete traceability of the collected air volume to international standards.
PERFORATED LIDS: FOUNDATION FOR MAXIMUM COLLECTION EFFICIENCY
The precision, robustness and material design of the perforated lid has a decisive influence on the collection efficiency and long-term stability of the measurement results. That is why we place the utmost importance on the uniformity of the holes, the accuracy of fit of the lid/instrument sealing surface and the ease of manipulation of the sampling lid - even when wearing gloves. The lids can be freely interchanged between instruments. This allows one unit to be used while another lid is being autoclaved.
CALIBRATION
All results of active microbial air samplers depend on correct air flow and air volume. That is why we ensure that the calibration of our instruments can be traced back to international standards via the certified MAS-100 Regulus digital anemometer and via our ISO 17025 accredited calibration laboratory. Each step in this cascade is fully documented, giving you the confidence to produce reliable results every time.

GOOD TO KNOW
IMPACTION PRINCIPLE in microbial air sampling
For active microbial air sampling based on the impaction principle, a predefined volume of air is drawn through a perforated sieve. The air and the particles in it are accelerated and directed onto a nutrient plate positioned below the sieve.
Due to inertia, particles above a certain size are impacted onto the nutrient medium. After appropriate incubation, microbe-bearing particles become visible as colony forming units (CFU), can be counted and reported as CFU/m3. The particle size at which 50% of the particles impact and the other half remain in the air stream is called the cut off diameter d50 (um).
Great emphasis is placed on precision in the manufacture of MBV perforated sieves. This ensures that the cut off diameter is identical in all holes and that microbial air sampling is repeatable.
