CELL CULTURE APPARATUS AND MEDIUM EXCHANGE METHOD

By swinging a culture vessel before aspiration removal of a medium, a centrally dense state (83) of the cell population is formed. In the centrally dense state (83), a cell cluster (84) is separated from an outlet port (58a). After aspiration removal of the medium, a new medium is introduced into the culture vessel. After the introduction of the new medium, an overall dispersed state of the cell population is formed.
