The utility model relates to a convenient pipette, which comprises an ear sucking ball, a supporting rod, a baffle plate, a pushing plate, a supporting frame, a pipette, and a graduation line. Pipette above the import and export of the sucking ball is fixed in a pipette, a supporting rod inside the sucking ball, the baffle and the support frame; the support frame is made of a thin rod, connected to the shift nozzle liquid pipe import and export, support is fixed to the point of this pick a supporting rod; the supporting rods two are respectively connected with the two ends of the baffle plates; the bottom end is connected with the nozzle baffle moving liquid pipe at the inlet and outlet, and the upper end of a sucking ball from a short distance, for the circulation of gas baffle width and pitch the inhalation of liquid to scale line is moved above the import and export of liquid pipe is connected with a push plate; the push plate is slightly wider than the width of the baffle, and the length is slightly longer than a sucking ball, pushing plate in the pipette end is movable. The utility model has the advantages of novel structure, simple use, high work efficiency, accurate control, and a series of tedious operations.
【技术实现步骤摘要】
一种便捷移液管
本技术涉及一种便捷移液管,属于化学器材
技术介绍
现有的化学试剂中的移液管使用过程大致为:左手拿吸耳球从移液管上管口将溶液吸上,当液面上升到到需要的刻度以上时,迅速用右手食指堵住管口,放液时稍微松开右手食指使液面缓缓下降。取此液过程中,从吸耳球移开到用右手食指堵住时,若动作不迅速会导致因液体下降过快而造成取液量不足;在放液时,松开手指或微微转动移液管过程中都均较难控制放液量;很难掌握精确的取放液,同时对操作者手指操作要求较高。
技术实现思路
本技术的目的:提供一种操作方便、控制精确、且结构新颖的移液管。本技术的技术方案是:一种便捷移液管,包括吸耳球1,支杆2,挡板3,推板4,支撑架5,移液管6,刻度线7。移液管6上方进出口接一个吸耳球1,且吸耳球1是固定在移液管上的,可以让操作更方便,在吸耳球1的内部有支杆2,挡板3和支撑架5;支撑架5由3个细棒组成,接在移液管6上管口进出口上,支撑架5上端固定为一点,这一点接一个支杆2;支杆2两个端点分别连接着两个挡板3;挡板3底端接移液管6上管口进出口上,上端与吸耳球离出一小段距离,供气体流通,移液管6上 ...
