The object of the present invention is to provide a technique for dispensing cells as single cells. The above problem can be solved by an apparatus for dispensing particles comprising a transparent hollow pipette for dispensing sample liquid containing particles, and an image capturing means, wherein the devise has means for capturing two or more images of the dispensing liquid in the hollow pipette; means for comparing two or more shot images, distinguishing a moved particle-like substance from an unmoved particle-like substance in the image-captured particle-like substances, and identifying the moved particle-like substance as a suspended particle; and means for dispensing a sample liquid containing a target number of suspended particles.

Fine particle dispensing device, fine particle analysis device, reaction detection device, and method using said devices

An object of the present invention is to purify and concentrate differentiating cells derived from ES cells, iPS cells, or the like without damaging them. The above problem can be solved by an apparatus for analyzing and separating particles comprising: a flow path cartridge, an illumination unit, a detection unit for detecting particles of interest, a force generating unit, wherein a sample liquid reservoir (sample reservoir) connected to a first flow path; a fourth branched flow path and a fifth branched flow path which are connected to the first flow path; a third-A reservoir connected to the fourth branched flow path; a third-B reservoir connected to the fifth branched flow path; and a fourth reservoir for reserving particles which are not sorting; are formed on the cartridge, and each reservoir comprise a means which equalizes an air pressure in the each reservoir with an air pressure of an in-device air pressure control system, and a stream of the flow path in the cartridge is controlled by controlling the air pressure in the each reservoir through the each in-device air pressure control system.
