ORUM INTERNATIONAL © ALL RIGHTS RESERVED SETTLE PLATE EXPOSURE UNDER UNIDIRECTIONAL AIR FLOW Articulate stainless steel support for Passive Air Sampling in table and floor model formats The settle method is applied with the culture plate in a horizontal or inclined position, according to the direction of the unidirectional air flow. In a horizontal position, air flow may be obstructed creating a slight turbulence over the surface of agar which could deviate the viable particles from the agar’s surface. A slanted position of the Petri dish allows the air to hit the agar surface and pass by without disturbance. TRIO.SETTLE is an articulate device developed to standardize, test, and enumerate the presence of microorganisms when applying the passive air monitoring, or settling plate, method. Passive air sampling provides a quantitative analysis of airborne microorganisms deposited onto the surface of an agar plate over a period of exposure. TRIO.SETTLE can be fixed on a tripod or other floor support devices. TRIO.SETTLE is fabricated from AISI 316 stainless steel and fully autoclavable. Validated according to “EN 17141”.

PASSIVE SAMPLING, COMBINED WITH ACTIVE SAMPLING, IS RECOGNIZED BY REGULATORY ORGANIZATIONS AS USEFUL IN ASSESSING THE MICROBIAL QUALITY OF THE AIR ENVIRONMENT. THE DIFFERENCE BETWEEN ACTIVE AIR SAMPLING AND PASSIVE AIR SAMPLING The Active Method: a predetermined volume of air is drawn onto an agar plate at a controlled rate of speed. An active air sampler provides an estimate of the number of microorganisms impacted onto an agar plate, free-floating or carried on particles, within a given size, within a cubic meter of air. The Passive Method: a static agar plate provides an indication of any...
