Abstract
A cartridge sealed from ambient air is used to send a liquid without causing the liquid to contact the fluid inside the cartridge. Inside of the cartridgesealed from ambient air are provided chambers that send and receive reagents, and an elastic body membraneis attached to the bottom surface. The cartridge main bodydoes not have a groove or anything else that becomes a channel, and the membraneis not bonded to portions that become channels. A channel, not formed in a normal state, is formed upon deforming the membraneunder 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.
