【技术实现步骤摘要】
本专利技术涉及一种离心管。
技术介绍
现今,离心管得到广泛应用,尤其是在生命科学中,例如:生物化学、分子生物学、细胞生物学、微生物等。在教育教学及科学实验中,离心管被广泛用于样品保存,化学反应,生物提取与分离,菌种保藏,细胞及微生物等培养,遗传物质扩译等。在医院中,生物及化学样品的保存与分析检测,也广泛应用到离心管。现今的离心管样品容易溢出,造成实验数据不准确,也使样品及环境受到污染,外界环境中的物质也容易进入离心管内造成样品污染。
技术实现思路
为了克服上述现有技术的不足,本专利技术的目的是提供一种离心管,通过管盖和管体V形的接触面使卡合更严密,解决了样品及环境易受污染的问题。为了实现上述目的,本专利技术采用如下技术方案:一种离心管,包括管盖和管体,所述管盖由盖顶和盖沿构成,所述盖沿由盖沿内壁和盖沿外壁构成,所述盖沿内壁和所述盖沿外壁之间形成纵截面为V形的结构,所述管体由管口、管筒和管底构成,所述管筒为圆柱筒形结构,所述管底为圆锥底,所述管口由管口内壁和管口外壁构成,所述管口内壁和所述 ...
