A cartridge sealed from ambient air is used to send a liquid without causing the liquid to contact the fluid inside the cartridge. This enables the reagents to be processed such as by being mixed, agitated, purified, and reacted while preventing contamination with suspended DNA in air. The cartridge has a simple structure to reduce the cost of the cartridge itself. Inside of the cartridge 1 sealed from ambient air are provided chambers that send and receive reagents, and an elastic body membrane 51 is attached to the bottom surface. The cartridge main body 51 does not have a groove or anything else that becomes a channel, and the membrane 51 is not bonded to portions that become channels. A channel, not formed in a normal state, is formed upon deforming the membrane 51 under air pressure in the unbonded portion, and the fluid is moved inside. A valve function is provided at an inlet of each chamber, and the fluid is internally moved in any direction with channel deformation. |
