摘要： A method for quality evaluation includes emitting measurement light having a wavelength of 300 nm or more and 2,000 nm or less to a cell mass and acquiring a plurality of light intensity information corresponding to each of a plurality of measuring positions in the cell mass, generating a feature amount from a variation of the acquired plurality of light intensity information, and evaluating quality of the cell mass using the generated feature amount as an index.

摘要： A cell observation container includes a first container configured to accommodate a culture solution, and a second container having one or more wells that are able to be put in and taken out of the first container while retaining one or both of cells and cell masses cultured in the culture solution. One or more wells each include a bottom portion that is able to retain the culture solution, and a side wall that extends from a peripheral portion of the bottom portion. A liquid passage portion through which the culture solution accommodated in the first container is able to pass is provided in the side wall.

摘要： A fine particle measurement device includes a support stand (20) that has a groove (F) extending in a predetermined direction and is configured to support in the groove an observation container (10), which has an elongate shape and accommodates a liquid sample containing a fine particle therein such that an extending direction of the groove (F) coincides with a longitudinal direction of the observation container (10); and an imaging unit (40) that is configured to capture an image of the fine particle in the observation container (10) at a position where the support stand is out of a field of view, the observation container (10) being supported by the support stand (20).
