【技术实现步骤摘要】
一种自发静电试管刷
本技术涉及一种自发静电试管刷,属于化学工艺领域。
技术介绍
众所周知,试管是实验室常用的仪器,用作于少量试剂的反应容器,。做实验时,需要用到不同直径的试管,在做完试验后,试管会被不同种的化学物质污染,为了重复利用且下次实验时不会被化学物质相互污染,需要对这些试管进行清理。由于试管的内径较小,清洗时需要借助工具,目前实验室常用的工具主要为试管刷,即通过试管刷摩擦试管壁的残留物(固体微粒),已达到清洗的目的。目前尝使用的试管刷多数是由刷杆和刷毛组成。刷杆多数是金属丝缠绕而成。刷毛经缠绕的金属丝固定在刷杆上。刷毛多数是由动物毛和塑料制成。该类试管刷容易使试管壁磨损,且不易清洗干净,尤其是针对异性试管。
技术实现思路
有鉴于此,本技术的目的在于提供一种自发静电试管刷,所述利用静电吸附试管壁的残留物(固体微粒),以避免试管刷的刷毛直接接触试管壁而使其磨损,且该试管刷尤其适用于异性试管。本技术的目的由以下技术方案实现:一种自发静电试管刷,所述试管刷包括把手、开关、线圈和刷毛;其中,所述把手包括手柄、刷头和连接杆;所述刷头为一端开口、另一端封闭的圆筒形结构,封闭端的 ...
