A Mohr pipette, also known as a Graduated pipette, is a type of pipette used to measure the volume of the liquid dispensed, although not as accurately as a volumetric pipette.[1] These use a series of marked lines (as on a graduated cylinder) to indicate the different volumes.[2] They come in a variety of sizes, and are used much like a burette, in that the volume is found by calculating the difference of the liquid level before and after.

The last graduation mark is some distance from the tip, to avoid errors in measuring the narrower volume of the nozzle.[3] It was invented by Karl Friedrich Mohr, the Father of Volumetric Analysis.

采用两次控制液面读数的普通的刻度吸液管即可以实现莫尔吸液管的功能。
莫尔移液管主要是为了避免吸液口尖端的干扰。
使用方式：刻度移液管配一个三通洗耳球，或者移液管控制器。
吸液后，读取一次体积，控制洗耳球放液结束后 再读取第二次体积。两者相减即为最终放出的体积

第一次听说，学习了

同版主，参加竞赛。请问莫尔吸量管在哪里可以买到？或者普通的吸量管参数和他一样吗，可不可以用普通的代替，拜谢！

同楼主参加同一个竞赛，哪里有关于mohr pipette的视频，求链接
