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.

很多实验室都使用通风橱。它可以将化学反应中生成的废气抽出，并引入新鲜空气，避免实验室中人员中毒。

A contact thermometer is different from a regular thermometer because of its sensor for the current temperature. Such a thermometer is connected with a heating coild. If the sensor notices that the aimed temperature has been reached the contact thermometer will make the heating coild stop heating. Therefore in an experiment it is possible to have a constant temperature.
|
|
|
|
|
接触式温度计与常规温度计的不同之处在于它的温度传感器。它可以与加热装置连接，当传感器发现温度已升高到设定温度时，它就可以使加热装置停止加热。这种特性使它常应用于恒温槽中。
