Abstract:
1. A reaction cartridge comprising: a first liquid reservoir having a first aperture for supplying a liquid, the first aperture being exposed to the atmosphere, and a second aperture which is adapted to be prevented from communicating with the atmosphere when the first liquid reservoir is supplied with the liquid; a first flow channel connected to the first liquid reservoir by way of the second aperture; a reaction chamber communicating with the first liquid reservoir by way of the first flow channel; a second flow channel connected to the reaction chamber; a third aperture for rendering the second flow channel to communicate with the outside; and a second liquid reservoir for storing waste liquid arranged between the second flow channel and the third aperture, the cartridge being configured to move the liquid supplied to the first liquid reservoir into the reaction chamber by reducing the pressure at the third aperture and to move the liquid moved into the reaction chamber back into the first liquid reservoir by increasing the pressure at the third aperture, the second liquid reservoir being connected with the second flow channel and the third aperture respectively at higher levels than a bottom part of the second liquid reservoir so that waste liquid may be retained in the second liquid reservoir even when the pressure at the third aperture is reduced or increased.
