Abstract: In order to present an arrangement method of nozzle holes of a capturing nozzle of an air-borne bacteria capturing apparatus in which dents are hardly formed on the carrier in an operation by rotating a petri dish containing a carrier, and sticking air-borne bacteria contained in the air sucked from nozzle holes formed in a capturing nozzle on the surface of the carrier by inertia, nozzle holes 11 of a capturing nozzle 1 of an air-borne bacteria capturing apparatus characterized by rotating a petri dish 3 containing a carrier 2, and sticking air-borne bacteria contained in the air sucked from the nozzle holes 11 formed in the capturing nozzle 1 on the surface of the carrier 2 by inertia are arranged by uniform random numbers, and the density of the nozzle holes 11 per unit area is uniform.

Abstract: [Problem] To present a storing method of a measuring apparatus of airborne floating bacteria capable of preventing contamination of the measuring apparatus by airborne floating bacteria and growth of airborne floating bacteria in the measuring apparatus during storage of the measuring apparatus of airborne floating bacteria. [Solving Means] In a storing method of a measuring apparatus of airborne floating bacteria for capturing airborne floating bacteria on a gel of a capturing carrier, forming into a sol in the measuring apparatus, and measuring the light emission of the ATP, the aseptic water existing in the piping system L of the measuring apparatus is displaced with alcohol, and dried, and the measuring apparatus of airborne floating bacteria is stored.

Abstract: Inspection arrangements of airborne floating bacteria for performing a biological light emission reaction by using an ATP light emission reagent on the basis of the ATP derived from viable cells in captured airborne floating bacteria in the air contained in the inspection sample, measuring the light emission quantity due to the biological light emission reaction, determining the ATP quantity contained in the inspection sample, and counting the number of cells in the airborne floating bacteria, the light emission quantity of the ATP light emission reagent is measured, and a measured value of light emission quantity of the ATP light emission reagent and a predetermined theoretical value corresponding to the measured value are compared, and thereby the reliability of the ATP light emission reagent to be used and the inspection results is evaluated at the same time.

Abstract: A mechanism for preventing suction air from leaking uses a capturing carrier cartridge that includes a cartridge main body and a filter fixing ring. The cartridge main body includes a storage portion for storing a capturing carrier solution and a filter mounting portion where a filter for filtering the capturing carrier solution is disposed. The filter fixing ring covers the filter mounting portion, positions the filter, and sucks and filters the capturing carrier solution from a lower surface thereof. The mechanism includes a cartridge holder and a suction head. The cartridge holder includes an opening that includes the filter mounting portion of the capturing carrier cartridge, and a holding portion that holds the storage portion. The suction head sucks the capturing carrier solution through the lower surface of the filter fixing ring while applying pressure to press the filter fixing ring against the filter mounting portion.
