Description

General description
The MAS-100 NT® microbial air monitoring systems are high performance, portable, battery operated instrument which are based on the principle of the Andersen air sampler. These compact yet sophisticated devices are the preferred choice for those demanding the highest quality in microbial air monitoring. A specified amount of air is aspirated through a 300-hole x 0.6 mm perforated lid and impacted onto the surface of growth media in standard 90-100 mm Petri dishes. Also 55-60 mm contact plates can be used with specified adapters and perforated lids. Microorganisms are impacted onto agar and, after an appropriate incubation period, the colonies are counted. The system measures the airflow and regulates it to a constant value of 100 standard liters/min. A Standard Liter Per Minute (SLPM) is adjusted to a specific environmental temperature and pressure, this ensure the amount of air sampled is always the same and independent of environmental conditions. These systems have the highest airflow accuracy of ± 2.5%, compared to others that can be as high as ±10%. The integrated flow sensor and high precision of perforated lids allows the user to freely interchange the perforated lids without affecting the accuracy or the calibration of the unit. The instruments are independently validated according to ISO 14698-1 with very good physical efficiency providing a D50 value below 1μm and a high biological efficiency result. The MAS-100 NT® is powered by a Lithium ion rechargeable battery with an intelligent charging program that assures long battery life without routine discharging.
Application
The MAS-100 NT® air sampler is used for microbial monitoring of ambient air in controlled environments up to ISO 5 cleanrooms. Microbial air sampling devices are extensively used in Pharmaceutical and Personal care industries as well as Food, Beverage and Environmental applications. Additionally, a regulation for compounding pharmacies, USP797, that requires active air sampling in the level 5 and above areas.
Other Notes
Now available: The new Safe Lid for the MAS-100 NT® air sampler

Safe Lid is a disposable, ready-to use alternative to the autoclavable standard perforated lid made from aluminum. It is made of 100% recyclable Acrylonitrile Butadiene Styrene (ABS) and comes in 30 individually double-packed and sterilized pieces per package. The Safe Lid has the same sieve configuration as the standard perforated lid with 300 holes of 0.6 mm diameter. This ensures an identical impact velocity of 19.6 m/s and anominal d50 of 1.1 μm. The simplified validation of the recovery rates according to EN 17141 resulted incomparable values for both perforated lids.

FAQs

Question: What sampling flow does the instrument maintain?

Answer:It automatically controls airflow at 100 standard liters per minute.

Question: Which culture plates are compatible?

Answer:Standard 90 mm Petri dishes can be used; smaller contact plates require suitable adapters.

Question: What is measured?

Answer:It collects viable airborne microorganisms onto growth media for incubation and colony counting.

Application Note

MAS-100 NT® is a portable, battery-powered air sampler for quantitative monitoring of viable airborne microorganisms in pharmaceutical cleanrooms and other controlled environments. The instrument draws air through a perforated impaction head so microorganisms are deposited onto the agar surface in compatible Petri dishes. It maintains a standardized sampling flow of 100 liters per minute using automatic flow compensation for temperature and pressure. A 300-hole head with 0.6 mm perforations supports efficient microbial collection. Standard 90 mm Petri dishes are compatible; smaller contact plates require the appropriate accessories. The approximately 2.3 kg unit is suitable for routine environmental monitoring and contamination-control programs, including sampling in high-grade cleanroom areas.
