Abstract
A method and apparatus for sampling microorganisms from the air is disclosed. The speed at which the sample is placed on to a growth medium is controlled, such as by controlling the speed of the turbine of the device, so as to compensate for any drying of the medium that may have occurred by the amount of air hitting the surface over time. This enhances the ability of the medium to retain microorganisms present in the air even as the medium dries from the flow of air over its surface.
