Deep hole plate with high nucleic acid extraction rate

The utility model provides a deep-hole plate with a high nucleic acid extraction rate and a preparation method of the deep-hole plate. The deep-hole plate with the high nucleic acid extraction rate comprises a containing cavity, and a plurality of deep-hole plate holes are formed in the containing cavity; the deep hole plate skirt edge is fixedly connected to the side edge of the accommodating cavity; the base is formed by extending the bottom of the skirt edge of the deep-hole plate towards the direction far away from the accommodating cavity; wherein an inner corner is arranged on the inner side of the deep hole plate hole. The deep hole plate with the high nucleic acid extraction rate has the characteristics of good biocompatibility and low nucleic acid adsorption. 本实用新型提供了一种高核酸提取率深孔板及其制备方法。一种高核酸提取率深孔板，包括容纳腔，所述容纳腔内设置有若干深孔板孔；深孔板裙边，固定连接于容纳腔的侧边；底座，由深孔板裙边的底部向远离容纳腔的方向延伸构成；其中，深孔板孔内侧设有内转角。本实用新型高核酸提取率深孔板具备良好的生物相容性和低核酸吸附的特点。
