Efficient DNA extraction plate

The utility model relates to the field of medical consumables, in particular to an efficient DNA (deoxyribonucleic acid) extraction plate which comprises a body and a plurality of DNA holes arrayed on the body, the DNA hole sequentially comprises an upper-end hole opening, a transition hole opening, a bottom hole body and a hole bottom from top to bottom, the cross section of the upper-end hole opening is square, the size of the upper-end hole opening is equal to that of the transition hole opening, and the inner diameters of the transition hole opening, the bottom hole body and the hole bottom are sequentially reduced, so that the whole DNA hole is square in the upper part and frustum-shaped in the bottom part. The device is simple in structure, convenient to use, capable of effectively preventing wall hanging and high in recovery efficiency. 本实用新型涉及医疗耗材领域，具体涉及高效DNA提取板，包括本体、阵列于本体上的若干个DNA孔；所述DNA孔自上而下依次包括上端孔口、过度孔口、底部孔身和孔底，所述上端孔口的横截面为方形，且上端孔口的大小与过度孔口的大小相等，所述过度孔口、底部孔身和孔底的内径依次减小使得DNA孔整体呈上部为方形、底部为锥台形。本实用新型结构简单、使用方
