CEM MAS-100 Microbial Air Monitoring System
- Compact design
- Easy to handle
- Mass flow of 100 LPM
- 90-day warranty
The CEM MAS-100 microbial air monitoring systems are high-performance instruments which are based on the principle of the Andersen air sampler. Ambient air is aspirated through a perforated lid and impacted onto the surface of growth media in standard 90-100 mm Petri dishes or 55-60 mm contact plates. Microorganisms adhere to the culture media, and after an appropriate incubation period, the colonies are counted. The system measures the inflow of air and regulates it to a constant value of 100 liters/min. MAS-100 air samplers comply with the guidelines of ISO 14698 parts 1 and 2 using ICR culture media and fully meet the d50 requirements.
These compact yet sophisticated devices are the preferred choice for those demanding the highest quality in microbial air monitoring. The MAS-100 system features a 300-hole perforated lid for increased collection efficiency and impaction speed. It utilizes standard 90-100mm agar plates or can be adapted to fit 50-60mm contact plates allowing for a low consumable cost and great flexibility. Sampling at 100 LPM, these systems have the highest airflow accuracy available at ± 2.5%, compared to others that can be as high as ±10%.

The integrated flow sensor allows the user to freely interchange the perforated lids without affecting the accuracy or the calibration of the unit. Sampling volumes are also easily configurable between 1 and 2,000 liters. The units have a horizontal air flow velocity of 0.45 meters per second and isokinetic flow rate that will not produce turbulence in a laminar flow environment.
All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.
The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
