SAS 180 & SAS 360 Air Samplers

A petri dish(es) containing appropriate agar medium is placed in the instrument. Air is aspirated at a fixed speed for variable time through a cover which has been machined with a series of small holes. The resulting laminar air flow is directed onto the surface of the agar plate. The agar plate is removed, shipped to our laboratory, incubated, and counted by our trained analysts.

Zefon Bio-Pump

The Zefon Bio-Pump is a portable, battery-powered pump that draws airborne particles through a tapered slitted orifice and impacts them on an adhesive-coated cover slip. The pump is the simplest and most convenient way to sample with Air-O-Cell and Allergenco cassettes. ​

Air-O-Cell cassettes are available through U.S. Micro-Solutions. Call 724-853-4047 for ordering information.
