Abstract: A culture vessel that can suppress foaming in a culture medium when a common nozzle is used to supply a liquid culture medium and a gas together. This culture vessel includes: a vessel body having an opening portion that communicates with a housing space; a lid that closes the opening portion; and a nozzle that passes through the and extends to the housing space, and supplies a liquid culture medium and a gas together. The nozzle has a vent opening portion that is formed so as to open in a side of the nozzle and serves as a movement path of the gas from inside of the nozzle into the housing space.

Abstract: A cell aggregate culture vessel (1) is a vessel for culturing a cell aggregate. The cell aggregate culture vessel (1) includes a well (21) having a culture space capable of storing the cell aggregate and culture fluid and a tubular body (3) which is disposed on the well on a plane at which the well has an opening and have an inner cavity communicating with the culture space, and one or more communication portion (3a) capable of discharging the culture fluid without allowing passage of the cell aggregate to the outside of the tubular body (3) is formed in a tubular wall of the tubular body (3). The communication portion (3a) may be, for example, a slit having a width of 0.1 mm or larger and 0.5 mm or smaller.

Abstract: A microwell plate includes a plate body having a surface on which wells are formed. Each of the wells has an open end, a bottom end and an interior space extended from the open end to the bottom end. Each of the wells has, in the interior space, an opening-side portion, a bottom-side portion and a transition portion which is continuously connected to the opening-side portion and to the bottom-side portion, the opening-side portion has a polygonal cross section in parallel to the surface of the plate body, and the bottom-side portion has cross sections in parallel to the surface which have areas that gradually decrease toward the bottom end.
