Disclosed is a nucleic acid extraction apparatus. The nucleic acid extraction apparatus comprises a workbench having a table top, and further comprises a sliding seat, a sample rack, a reagent strip rack, a pipetting table, a piston assembly and a suction assembly. The nucleic acid extraction apparatus comprises the sliding seat and the pipetting table, the sample rack and the reagent strip rack are arranged on the sliding seat, the piston assembly and the suction assembly are respectively arranged on the pipetting table, the sample rack is provided with sample holes, the reagent strip rack is provided with accommodation slots, the number of accommodation slots corresponds to that of the sample holes on a one-to-one basis, and when reagent strips are respectively accommodated in the accommodation slots, a first suction head hole, second suction head holes and various reagent holes in each reagent strip respectively correspond to the corresponding sample holes, such that the loading of a suction head assembly and suction heads and operations such as suction, injection and mixing of a sample and various reagents can be realized by means of a vertical movement, relative to the sliding seat, of the pipetting table and a horizontal movement, relative to the pipetting table, of the sliding seat, thereby realizing the automated operation of nucleic acid extraction. |
