Abstract
There is the problem that a liquid culture medium fed by a pump has a high frequency of contact with a gas during movement in a tube, and the pH value of the liquid culture medium before and after feeding changes easily. In a liquid feeder and a cell culture apparatus provided therewith, a feed pipe 7 is connected with a gas bag 14, the liquid to be fed into the feed pipe 7 is fed so as to be sandwiched by a gas for suppressing the qualitative changes of the liquid. Furthermore, the gas bag is connected with a container 8 for holding a liquid, and holds the gas for suppressing qualitative changes of the liquid in a gas phase of the container.
