To separate a mixture you can use distillation amongst others. The distillation bridge is thereby the way between the two pots. In the one pot there is the mixture to be separated. Through heating, a gas forms which is lead through the bridge. At the end of the bridge the gas phase is condensed again and drips in a round flask. As a rule, the bridge is cooled by return flow. In addition, there is often a thermometer for controlling the temperature on the distillation bridge.

精馏管可以用来分离混合物。精馏管有两个出口,其中的一个出口是接分离物的。当加热时,热气流通过精馏管,在精馏管的末端凝结,流入一个圆底烧杯中。精馏管的冷却一般是靠气冷。而且在精馏管中常用温度计来控制温度。

A syringe consists of two parts: A glass tube and a punch. Both are normally made of glass. A gas floats into the glass tube. As the syringe is a closed system the punch has to give way. This can be used measuring the volume of an reaction.

注射器由两部分组成:一根玻璃管和一根冲杆。这两样通常都是用玻璃做的。当气体进入玻璃管时,由于注射器是密封的,冲杆就被压出。这样就可以测量反应气体的量了。译者注:化学实验中这么大的注射器只用来作流量计用。

At the four ends of this separation beaker you put four small caps. While distilling, you can turn the beaker by 60 degree after a certain temperate has been reached. This way, at the end of the distillation all four caps have a specific liquid in it, depending on the boiling points of the liquid distilled.

分离烧杯有四个口,每个口都配有小盖子。在蒸馏时,您可在到达一定温度时就将烧杯旋转60度,这要蒸馏后四个小盖子里都会有特殊的液体,这取决于这些液体的沸点。

There are several types of burners. The picture shows a Teclu-Burner. Each type has specific uses. They vary in the peak temperature and overall heating capability.

Most laboratories use extractor hoods. They filter the gasses from chemical reactions and pump the cleaned air outside of the building.
