Abstract: Provided is a spectroscopic analysis apparatus including: an optical probe; and a spectroscopic analysis portion to which the optical probe is attached. The optical probe includes an optical fiber that guides illumination light coming from a light source and signal light coming from an observation target and an optical member that is disposed at least at a distal end of the optical fiber. The spectroscopic analysis portion includes an information separation portion that generates wavelength dependent characteristics by optically dispersing the signal light and that separates, from information about the signal light, information about first return light returning from the optical member and information about second return light returning from the optical fiber, a problem determining portion that determines a problem occurring at the optical probe based on the separated first return light and second return light, and a notification portion that notifies information about the determined problem.

Abstract: A cell culturing device includes: a sensor that measures a pH of a medium in which cells are being cultured; and one or more processors including hardware. The one or more processors are configured to: measure an elapsed time since the cells were seeded in the medium; determine whether the measured pH is lower than a prescribed threshold and whether the measured elapsed time has passed a prescribed time; and issue an instruction for medium replacement in response to determining that the pH is lower than the prescribed threshold or in response to determining that the elapsed time has passed the prescribed time.

Abstract: An observation system includes an illumination unit including a light source from which emits an illumination light including light of a plurality of colors, and light receiving unit including an optical sensor which acquires a light intensity. The illumination unit emits the illumination light for a culture vessel so that the illumination light travels from a first side to a second side of the culture vessel, the first side and the second side being defined by interposing a culture medium. The light receiving unit receives, on the first side, light emitted from the illumination unit, entering the culture vessel from the first side, reflected at the second side, and transmitted through the culture medium, and acquires a light intensity for each color in the received light for calculation of a pH value of the culture medium.

Abstract: A medium changing device includes a lid disposed at a position where two or more regions in which a medium may be stored are covered therewith, the regions being disposed adjacent to each other and being open upward; one or more flow-path members each disposed so as to penetrate the lid, and each disposed at a position where one of the regions is bridged to another therewith when the lid is disposed at the position where the regions are covered; and a pump disposed on the other side of the lid and acting on the intermediate sections of the flow-path members, exposed on the other side, so as to cause the medium to flow from the opening at one end toward the opening at the other end of each of the flow-path members.
