摘要： This fluid handling device has a rotary member that is rotatable around the central axis. In the rotary member, a first protruding part for pressing and closing a valve of a flow channel chip and a recessed part for opening the valve without pressing the valve are disposed on the circumference of a first circle around the central axis. The rotary member further has a second protruding part for, when the recessed part is located at the valve in a state where the rotary member is rotated, pressing the valve so as not to open the valve.

摘要： A fluid handling device includes a first channel, a second channel, and a valve disposed at a connection part between the first channel and the second channel. The valve include a partition wall disposed between the first channel and the second channel, and a diaphragm disposed so as to face the partition wall, a portion of the first channel, and a portion of the second channel. The diaphragm is configured in such a way that when no pressure is applied to the diaphragm, a gap, which serves as a third channel that allows the first channel and the second channel to communicate with each other, is formed between the diaphragm and the partition wall. In plan view, the length of the diaphragm in the extending direction of the third channel is longer than the length of the diaphragm in the direction orthogonal to the extending direction.

摘要： A fluid handling device includes: an introduction part configured to introduce liquid; an ejection part configured to eject liquid; a channel including one end connected to the introduction part and another end connected to the ejection part; and a valve disposed at the channel. An inner surface of the introduction part has water-repellency, and an inner surface of the ejection part and at least a part of an inner surface of the channel do not have water-repellency.

摘要： A flow channel chip has: a common flow channel; introduction flow channels that are respectively connected to the common flow channel; introduction valves that are respectively disposed in the introduction flow channels; a cleaning liquid flow channel that is connected to the common flow channel; and a cleaning liquid valve that is disposed in the cleaning liquid flow channel. This fluid handling device has: a rotary member for controlling opening/closing of the introduction valves; and a cleaning liquid valve control unit for controlling opening/closing of the cleaning liquid valve. After the rotary member is rotated so as to open/close one of the introduction valves, the cleaning liquid valve control unit causes the cleaning liquid valve to open and causes the cleaning liquid to flow in the common flow channel before the rotary member is rotated so as to open/close another of the introduction valves.

摘要： This liquid handling apparatus has a single introduction part that opens on a first surface side of a substrate and is for introducing a liquid, a plurality of discharge parts that open on the first surface side of the substrate and are for discharging the liquid that has been introduced through the single introduction part, a flow path for connecting the single introduction part and the plurality of discharge parts within the substrate, and a plurality of outflow prevention parts that are disposed so as to surround the openings of the plurality of discharge parts and are for using the surface tension of the liquid to check the progress of the outflow of the liquid from the discharge parts. For each opening part, there are two or more outflow prevention parts disposed so as to surround the opening part.
