Abstract
After supporting a petri dish S having a culture medium K contained therein with a given thickness on a petri dish holder 17 of a housing 14, a nozzle holder 13 is clamped at a top of the housing 14. When a motor 19 is energized to rotate a high static pressure fan 18, air is introduced through nozzle openings 12a, and flows through a space between the nozzle 15 and the culture medium K. By setting a distance between the nozzle and the culture medium to 0.5-1.5 mm, a high collection efficiency can be attained.
