Patent ID: 7326386

Claim:
An apparatus for extracting nucleic acid, comprising: a nucleic acid extraction cartridge equipped with a filter member adapted to adsorb nucleic acid molecules, wherein the cartridge is adapted to be pressurized; a first structure adapted to hold the nucleic acid extraction cartridge; a waste liquid container; a recovering container; a second structure adapted to hold the waste liquid container and the recovering container; a third structure adapted to hold both the first structure and the second structure; a holding mechanism comprising the first structure, the second structure and the third structure; an apparatus main body; a pressurized air feeding mechanism having a single pressurizing nozzle adapted to introduce a pressurized air into the cartridge through the single pressurizing nozzle; a dispensing mechanism having a first dispensing nozzle and a second dispensing nozzle adapted to dispense a washing solution and a recovering solution into the cartridge, respectively; and a moving mechanism adapted to relatively move the pressurizing nozzle of the pressurized air feeding mechanism to the holding mechanism, wherein the third structure is attachable to and detachable from the apparatus main body, wherein the second structure comprises a casing comprising a plurality of insertion ports for a microtube with a cap, wherein the plurality of insertion ports are juxtaposed on an upper surface of the casing, wherein the apparatus further comprises; a press-bending member rotatably supported around an axis of a juxtaposition direction of the plurality of insertion ports provided on the casing, and wherein the press-bending member is adapted to hold a cap portion of the microtube with the cap by press-bending the cap portion projected from the casing downward, in the second structure.
