摘要： Provided is a liquid feeding device, including: a test container including a first accommodation portion, a second accommodation portion, and a third accommodation portion each accommodating a liquid, a first flow path connecting the first accommodation portion and the second accommodation portion to each other at respective upper end positions thereof, and a second flow path connecting the second accommodation portion and the third accommodation portion to each other at respective upper end positions thereof, in which at least a portion forming an upper wall surface of the second accommodation portion has flexibility; and a pressing machine which includes a first pressing portion and presses the portion forming the upper wall surface of the second accommodation portion at a position closer to the first flow path from a center in a liquid feeding direction towards an inside of the second accommodation portion from an outside by the pressing portion, in which the liquid accommodated in the second accommodation portion is fed to the third accommodation portion by pressing the portion forming the upper wall surface of the second accommodation portion with the pressing machine.

摘要： In a container including two accommodation parts each accommodating liquid, mixing of the liquids in a case of moving magnetic particles in the liquid accommodated in one accommodation part to the other accommodation part is suppressed. Provided is a container includes a first accommodation part which accommodates a first liquid containing magnetic particles, a second accommodation part which accommodates separated magnetic particles separated from the first liquid, and a second liquid, and a flow passage which allows the first accommodation part and the second accommodation part to communicate with each other, and through which the separated magnetic particles pass, in which the flow passage has a first staircase part including two or more steps from an inner bottom surface of the first accommodation part on a first accommodation part side.

摘要： A test container including: at least two accommodation portions each accommodating a liquid and internally provided; a flow path connecting the two accommodation portions to each other at respective upper end positions thereof internally provided; and a flexible film deformable inwards of at least one accommodation portion at a portion forming an upper wall surface of the one accommodation portion, in which the liquid accommodated in the one accommodation portion is fed to the other accommodation portion via the flow path due to deformation of the flexible film towards the one accommodation portion, and a breaking elongation of the flexible film is 100% or more and 600% or less.

摘要： A test container includes a container main body including a first-accommodation-portion, a second-accommodation-portion, and a third-accommodation-portion each accommodating a liquid and internally provided, a first flow path connecting the first-accommodation-portion and the second-accommodation-portion to each other at respective upper end positions thereof and internally provided, and a second flow path connecting the second-accommodation-portion and the third-accommodation-portion to each other at respective upper end positions thereof and internally provided, in which at least a portion forming an upper wall surface of the second-accommodation-portion has flexibility to be deformable inwards of the second-accommodation-portion; and a liquid return prevention structure which prevents a backflow of the liquid to the first-accommodation-portion, when the liquid accommodated in the second-accommodation-portion is fed to the third-accommodation-portion via the second flow path due to deformation of the portion forming the upper wall surface of the second-accommodation-portion inwards of the second-accommodation-portion.
