    In a typical impactor sampler air is drawn into a sampling head by a pump or fan and accelerated, usually through a perforated plate (sieve samplers), or through a narrow slit (slit samplers). This produces laminar air flow onto the collection surface, often a standard agar plate or contact plate filled with a suitable agar medium.

    BioCassette® Device - EMLab P&K

    The BioCassette ® is a registered sampling device developed by Eurofins EMLab P&K for viable (culturable) air samples. This invention combines the agar plate and the design of the Andersen N6 impactor into a single, disposable cassette and is equivalent to the size of a standard 90mm petri dish.
