  • Publication number: 20050244308
    Abstract: A chemical reaction cartridge includes a vessel having at least one part made of an elastic body, in which a plurality of chambers formed in the vessel so as to be connected or arranged connectably through a flow path, and an external force is applied to the elastic body from an outside of the vessel to move a fluid substance in the flow path or the chambers or in both the flow path and the chambers so as to perform a chemical reaction. At least a chamber into which the fluid substance is flowed has an air-release path which releases air from the chamber.
