摘要： 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.

摘要： An automatic culture device which employs closed-system culture vessels and in which, when a passage part (2) and a rotational valve mechanism (3) are configured, the multiple culture vessels in a culture vessel part (1) can be rendered equal in liquid-feeding conditions by, for example, regulating the length of each passage. As a result, the evenness in quality of cells incubated in the multiple culture vessels is rendered possible. Furthermore, by providing a mechanism which enables a user to normally set passages in the device, the evenness in quality of the cells is rendered possible likewise.

摘要： Maintaining pressure inside a culturing vessel is difficult when minimizing the size of a liquid supply path that supplies liquid and gas to a cell culturing vessel that performs two-level culturing (co-culturing). This cell culturing device includes: culturing vessels; a flow path having at least first supply ports capable of supplying liquid or gas to the culturing vessels and first discharge ports that discharge the gas from the culturing vessels, said flow path discharging gas from the first discharge ports to the atmosphere; and a filter in the flow path. A trap bottle is provided between the first discharge ports and the filter upon the flow path to collect moisture from the discharged gas. Thus, a liquid phase and a gas phase are separated in the trap bottle; moisture is prevented from reaching the filter; filter clogging is prevented; and the internal pressure of the culturing vessels can be maintained.
