Abstract: Provided are a nucleic acid analysis device and a nucleic acid extraction device that allow appropriate setting of a container to the device. A nucleic acid analysis device includes a plurality of amplification container setting parts each configured to have an amplification container set thereto, the amplification container being configured to have injected therein an extract that contains nucleic acid, the amplification container storing a reagent for amplifying the nucleic acid in the extract; a display unit; and a controller configured to cause the display unit to display a screen in which a location of each of the plurality of amplification container setting parts is associated with relevant information regarding setting of the amplification container to the amplification container setting part.

Abstract: A flow cytometer comprises a flow cell configured to induce a flow of a sample containing object particles, a light source, an irradiating optical system configured to irradiate light from the light source on the flow of particles in the flow cell, a detecting part configured to detect light given off from the flow of particles which are irradiated by light. The irradiating optical system comprises a collective lens having an optical axis symmetric aspherical surface on one surface, and a cylindrical surface on the other surface.
