Analysis device

An examination apparatusfor microorganisms for measuring an amount of microorganisms in a sample solution, the apparatus including stirring and mixing meansfor stirring and mixing the sample solution into which a sample and a fluorescent staining reagent are added, in a sample containerformed of a material allowing light to pass through, an excitation light sourceincluding a light source that irradiates an irradiation target surface of the sample containerwith excitation light while the sample solution is being stirred by the stirring and mixing means, light receiving meansfor detecting light and converting the light resulting from a fluorescent emission caused by excitation light from the excitation light source, into an electric signal, and control meansfor detecting the number of emissions based on the electric signal from the light receiving meansand calculating the amount of the microorganisms contained in the sample in the sample containerbased on the number of emissions.

Method for examining microorganisms and examination apparatus for microorganisms

A method for examining microorganisms has a sampling preparation step including a fluorescence staining step of stirring and mixing certain amounts of a sample and a fluorescence staining reagent, a still standing step of leaving the solution after the fluorescence staining step to still stand for a certain time, and a dilution step of diluting the solution after the still standing step with a liquid that emits no fluorescence.
