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.

Abstract: Sample fine particles attached to an inspection object are identified simply and with high accuracy, and an increase in operation rate and a decrease in device size are achieved. The inspection object is transported into a sampling chamber defined by a pair of side walls and an upper wall enclosing a part of a transport route of a transport unit. The inspection object is sprayed with compressed gas from an air nozzle, the peeled sample fine particles are aspirated into a collector, and the sample fine particles are separated from the aspirated gas for analysis. The air nozzle is disposed on one of the side walls defining the sampling chamber. The collector is disposed under the other side wall as a container independent from the sampling chamber.

Abstract: 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.

Abstract: In a conventional fine particle detection device that vaporizes fine particles attached to the object of examination by heating, processing capability decreases as the processing time elapses due to the influence of deposition of fine particles other than the object of examination, dirt/dust, a residue of the fine particles as the object of examination, or residual matter. A fine particle detection device according to the present invention includes: a vaporization device that vaporizes the fine particles trapped by a trap device by vaporization or decomposition; a first flow passageway in which a mixture of a component vaporized by the vaporization device and another component flows; a second flow passageway branching from the first flow passageway in a direction of inertial force acting on the other component; a third flow passageway branching from the first flow passageway in a direction different from the direction of the inertial force; and an analysis device that analyzes a component introduced into the third flow passageway.
