摘要： A microchannel chip (1) includes: a first channel (201); a reagent holder (230); a gas inlet (210) communicating with the first channel; a lid (50) closing the gas inlet; and a second channel (202) provided downstream of the first channel. A specimen holder (240) is provided downstream of the reagent holder (230). When the lid (50) closes the gas inlet (210), gas is supplied to the first channel (201) and pushes out the reagent downstream from the reagent holder (230). Thus, the pushed-out reagent merges with a specimen in the second channel (202).

摘要： Provided is a chip that does not require high-accuracy discharge amount control for a liquid delivery pump and can suppress the entrainment of air bubbles. A chip 1 for test or analysis is provided with a flow path 4 through which a fluid is delivered, the chip 1 including: a first flow path 5 through which a first fluid is delivered; a second flow path 6 through which a second fluid is delivered; a merging portion 8 configured to be provided on a downstream end portion 5a side of the first flow path 5 and merge the first fluid and the second fluid; a first connection flow path 9 configured to connect the first flow path 5 and the second flow path 6 at the merging portion 8 and have a liquid delivery resistance higher than a liquid delivery resistance of the first flow path 5; a degassing flow path 13 configured to be connected to the second flow path 6 on a downstream side of the first connection flow path 9; a third flow path 7 configured to be provided on a downstream side of the merging portion 8; and a second connection flow path 10 configured to connect the first flow path 5 and the third flow path 7 and have a liquid delivery resistance higher than the liquid delivery resistance of the first flow path 5.
