Intended use
Principle
The Surface Air System (SAS) encompasses several models which use the same principle. Air is aspirated at a
fixed speed for variable time through a head which has been machined with a series of small holes of a special
design. The resulting laminar airflow is directed onto the agar surface of a “RODAC Plate” (or a Petri dish)
containing medium for microbiological analysis.
When the selected sampling cycle is completed, the plate is removed and incubated. The organisms are then visible
to the naked eye and can be counted for the assessment of contamination levels.
