Claim 0:
1. A sample analysis substrate having a microchannel structure for transferring a liquid through rotary motion, comprising:
a substrate body having a rotation axis;
a first container having a first contact surface and holding a first liquid therein;
a second container having a second contact surface and holding a second liquid therein;
a first accommodating section located in the substrate body and accommodating the first container in such a manner that the first container is movable between a first holding position in which the first container is held and a first release position in which the first liquid can be released from the first container;
a second accommodating section located in the substrate body and accommodating the second container in such a manner that the second container is movable between a second holding position in which the second container is held and a second release position in which the second liquid can be released from the second container; and
a cap having a first drive projection and a second drive projection and movably supported on the substrate body, wherein as the cap moves, the first drive projection and the second drive projection come into contact with the first contact surface and the second contact surface, respectively, thereby moving the first container and the second container from the first holding position and the second holding position to the first release position and the second release position,
wherein the cap is capable of taking:
a first position where the first container and the second container are in the first holding position and the second holding position, respectively, in which only the first drive projection is in contact with the first contact surface;
a second position where the first container is located between the first holding position and the first release position and the second container is in the second holding position, in which the first drive projection and the second drive projection are in contact with the first contact surface and the second contact surface; and
a third position where the first container and the second container are in the first release position and the second release position, respectively, in which the first drive projection and the second drive projection are in contact with the first contact surface and the second contact surface, respectively.
