    Abstract: A device which automatically performs a step in which expanded and cultured cells are diluted to a desired cell concentration and re-inoculated using a cell-concentration adjustment device having an inlet for taking in a cell suspension; an outlet for discharging a diluted cell suspension; and a flow path which is provided between the inlet and the outlet and is capable of holding a cell suspension, the flow path being provided with: a liquid delivery pump for causing a cell suspension inside to flow; a cell-concentration measurement instrument for collecting data related to a cell concentration per unit amount of the cell suspension; and a dilution-liquid container for holding a dilution liquid which is supplied to the flow path to dilute the cell suspension. The device further includes a control unit for controlling at least the liquid delivery pump on the basis of the data obtained by the cell-concentration measurement instrument, wherein the control unit determines, on the basis of the data obtained by the cell-concentration measurement instrument, an amount of the dilution liquid required to bring the cell concentration to the desired concentration, and drives the liquid delivery pump so as to take in the required amount of the dilution liquid into the flow path and mix the cell suspension and the dilution liquid.

    Abstract: The purpose of the present invention is to provide a means for dispersing cell aggregates without damaging the cells, such that a sufficient multiplication rate can be obtained in a subculture. According to the present invention, provided is a cell-suspension processing device which disperses cell aggregates included in a cell suspension. The device is provided with: an inlet for taking in the cell suspension; an outlet for discharging the processed cell suspension; and a flow path which is provided between the inlet and the outlet, and which is capable of holding the cell suspension. The flow path has, provided thereto, a liquid delivery pump for causing the cell suspension inside to flow, a cell-dispersion-degree measurement instrument for measuring the dispersion degree of cells in the cell suspension, and a narrow part for imparting shearing force to the cell suspension flowing inside. The cell-suspension processing device is further provided with a control unit for controlling at least the liquid delivery pump on the basis of data obtained by the cell-dispersion-degree measurement instrument. The control unit determines whether the cells have attained a prescribed dispersion degree on the basis of the data obtained by the cell-dispersion-degree measurement instrument, and, in cases when the cells have not attained the prescribed dispersion degree, drives the liquid delivery pump such that the cell suspension is passed through the narrow part.

    Abstract: According to the present invention, a simple structure can be used to achieve reliable liquid delivery with no residual air, and simple attachment/detachment of a culture vessel, and thus a closed-system cell culture device exhibiting high reliability can be constructed at low cost. In the present invention, a liquid is supplied or discharged while a culture vessel is in an inclined state. The culture vessel is provided with two flow paths, namely an intake flow path and a discharge flow path, which connect a culture chamber and a connection member. Points where the flow paths join with the culture chamber are respectively configured as an intake port and a discharge port. The discharge port is provided in the position nearest to the axis of inclination of the culture vessel. The intake port is provided in a plane projected from a vertical plane including the aforementioned axis of inclination.

    Abstract: A sterile connector has a first connector including a first housing provided with a first flow channel; a first pipeline connected to the first flow channel; first and second openings, the first opening being positioned inward from the second opening; and a first sealing member covering the second opening. Also, a second connector includes a second housing provided with a second flow channel; a third opening; and a second sealing member covering the third opening. The first and second connectors are detachable from each other. The first sealing member seals a space between the inner circumferential surface of the first housing and the outer circumferential surface of the second housing, while the second sealing member seals a space between the inner circumferential surface of the second housing and the outer circumferential surface of the first pipeline so that the first flow channel communicates with the second flow channel.
