记得以前我们系的一个教授说过他读研究生那会（大概是70年代），离心机是手摇的，
LOL
【在 b**********8 的大作中提到】
: 最近试验郁闷了，枯燥之余来点有意思的话题调解下，这两样东东是什么时候出现的，
: 之前科学家们是用什么东东代替这两样东西的？

那么手摇式离心机出现之前呢？用什么离心？
还有移液器，没有这个东东的时候是用什么准确取样的，特别是那种微升级的微量样品
？

离心机肯定在二战的时候已经成熟了，造原子弹不是要这玩意嘛
English military engineer Benjamin Robins (1707–1751) invented a whirling
arm apparatus to determine drag. In 1864, Antonin Prandtl invented the first
dairy centrifuge in order to separate cream from milk. In 1879, Gustaf de
Laval demonstrated the first continuous centrifugal separator, making its
commercial application feasible.

移液器肯定发明的迟，分子生物学没出现之前没有用到它的必要性，谁没事加微升级的
样品，化学的话也是滴定滴定完事。
These micropipette were invented and patented 1960 by Dr. Hanns Schmitz (
Marburg/ Germany). Afterwards, the co-founder of the biotechnology company
Eppendorf, Dr. Heinrich Netheler, inherited the rights and initiated the
global and general use of micropipettes in labs. In 1972, the adjustable
micropipette was invented at the University of Wisconsin-Madison by several
people , primarily inventor Warren Gilson and Henry Lardy, hence one of the
bigger producers is the original company called Gilson Inc., as a result
they are colloquially referred to as Gilsons
