Description:
FSC-A6 Six Stage Microbial Air Samplers are multi-orifice, cascade impactors used to measure the concentration and particle size distribution of aerobic bacteria and fungi in the intramural or ambient air. These units have been widely used for enumerating the viable particles in a microbial aerosol. Viable particles can be collected on a variety of bacteriological agar and incubated in situ for counting or identification. These samplers are designed so that all particles collected, regardless of physical size, shape, or density are sized aerodynamically and can be directly related to human lung deposition.
The multi-orifice cascade impactor size selective feature permits assessment of an airborne contaminant in relation to its disease potential arising from its deposition site within the respiratory tract.
The Honri Airclean FSC-A6 Six Stage Microbial Air Sampler requires 12 glass Petri dishes. and a general purpose, solid bacteriological agar medium (not included), which is placed in six of the glass Petri dishes. The collection plate with Petri dishes are inserted on each stage of the sampling instrument and a sample of air is drawn. The petri dishes are then removed, inverted in their covers, incubated and counted by an accepted method.

This model is constructed with six aluminum stages that are held together by three spring clamps and sealed with 0-ring gaskets. Each impactor stage contains multiple precision drilled orifices. When air is drawn through the sampler, multiple jets of air in each stage direct any airborne particles toward the surface of the agar collection surface for the stage. The sizes of the jet orifices are constant within each stage, but are smaller in each succeeding stage, the range of particle sizes collected on each stage depends on the jet velocity of the stage and the cutoff of the previous stage. Any particle not collected on the first stage follows the air stream around the edge of the Petri dish to the next stage.
