Abstract
After supporting a petri dish S having a culture medium K contained therein with a given thickness on a petri dish holder of a housing , a nozzle holder is clamped at a top of the housing . When a motor is energized to rotate a high static pressure fan , air is introduced through nozzle openings , and flows through a space between the nozzle 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.
