Miniature drill bit for molecular biology laboratory

The utility model discloses a micro drill bit for a molecular biology laboratory, and particularly relates to the technical field of drill bits. A miniature drill bit for a molecular biology laboratory comprises a stepped drill bit body, four crushing teeth are symmetrically arranged at the small-diameter end of the drill bit body, every two crushing teeth on the same side are located in the same plane, and each crushing tooth does not exceed the outer edge of the drill bit body. By the adoption of the technical scheme, the problems that an existing homogenizer is large in size, high in price and incapable of homogenizing trace samples are solved, and the homogenizer can be applied to animal and plant homogenizing operation with the extracting solution being less than 0.2 mL. 本实用新型专利公开了一种用于分子生物实验室的微型钻头，具体涉及钻头技术领域。一种用于分子生物实验室的微型钻头，包括阶梯状的钻头本体，所述钻头本体上直径小的一端对称设有四个破碎齿，同一侧的两个所述破碎齿位于同一平面内，每个所述破碎齿均未超出钻头本体的外缘。采用本实用新型技术方案解决了现有的匀浆机体积大、价格昂贵、同时无法对微量样品进行匀浆的问题，可应用于提取液少于0.2mL的动植物匀浆操作。
