The invention relates to the field of kits, and particularly discloses
a DNA extraction kit. The
DNA extraction kit comprises a kit body, a rotating structure, a fixing structure, a clamping structure, a freezing structure, a drawing structure and a moving structure. The rotating structure is installed inside the kit body, so that the sealing protection effect on the kit body can be achieved, and it can be ensured that a
test tube placed inside the kit body is always in a vertical state, thus, the circumstance that the
test tube leaks liquid when the kit body is transported can be avoided, and the
transportation safety of reagents is greatly improved; in cooperation with the freezing structure installed inside the kit body, the
refrigeration effect on the reagents placed inside the kit body can be achieved, water drops condensed outside can be collected and treated in a centralized mode, rapid assembling and disassembling can be realized, and the operation is facilitated; and the fixing structure is arranged inside the rotating structure for placing the
test tube, so that the outer side wall of the inserted test tube can be locked and fixed, the circumstance that the test tube shakes when the reagents are transported is avoided, and liquid leakage is prevented.
