Bio-Sampler Hire Kit

MAS-100 Microbial Air Samplers comply with the guidelines as specified in ISO 14698 part 1 and part 2

State-of-the-art mass flow sensor to ensure a constant air flow rate of 100 liters/min.

Continues regulation of air flow during sample collection

Automatic adjustment to different volume fills of Petri dishes, changes in air density and differences between individual perforated lids.

The MAS-100  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. 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 is powered by a Lithium ion rechargeable battery with an intelligent charging program that assures long battery life without routine discharging.
