  • Patent number: 10597621
    Abstract: Disclosed is a rotating culture vessel based on a rotating culture technology using an RWV, by which cell seeding, liquid medium exchange, quality control and so on can be automated and degassing can be conducted simultaneously with liquid medium exchange without disturbing the cells under culture. Also disclosed is an automatic cell culture apparatus using the same. A rotating culture vessel, which contains cells and a liquid culture medium, to be attached to a horizontal rotating shaft of a rotating culture device to three-dimensionally culture the cells, wherein one or more inlets/outlets for supplying cells and a liquid culture medium at the early stage and then taking out the cultured cells, are formed at appropriate position of a flat cylindrical culture container; at least one pair of a supply port and a discharge port for liquid medium exchange is provided on the outer circumferential cylindrical face of the culture container.
