ARRANGEMENT METHOD OF NOZZLE HOLES OF CAPTURING NOZZLE OF AIR-BORNE BACTERIA CAPTURING APPARATUS AND AIR-BORNE BACTERIA CAPTURING APPARATUS

摘要

The purpose of the present invention is to provide a method for arranging nozzle holes of a collector nozzle in an airborne microorganism collection device, whereby, in the case of rotating a petri dish containing a support and, at the same time, allowing airborne microorganisms, which are contained in air sucked in through the nozzle holes formed in the collector nozzle, to stick to the surface of said support because of inertia, a depression in the support is minimized. In an airborne microorganism collection device, a petri dish (3) containing a support (2) is rotated and, at the same time, airborne microorganisms, which are contained in air sucked in through nozzle holes (11) formed in a collector nozzle (1), are stuck to the surface of the support (2) because of inertia. The nozzle holes (11) of the collector nozzle (1) are arranged using uniform random numbers so as to uniformize the density of the nozzle holes (11) per unit area.
