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.

燃烧炉有很多种。图片中的是特克卢燃烧炉。每种燃烧炉都有特定的用途。它们的最大温度都可调而且加热均匀。

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。

With clamps as used in a laboratory you can easily hold all kinds of tools.

There are multiple way to measure the pH-Value of an solution. With a litmus paper it is easy to get a pretty precise pH-Value. The color indicates the value. If you need a more precise value you can for example use a pH-Meter which is using the conductivity of a solution.

有很多种办法测试溶液的PH值。应用石蕊试纸可以轻易地到一个精确的PH值。试纸的颜色指示了这个值。如果您需要一个更精确的值,您可以使用PH计,它采用的是通过PH电极测量溶液的电导率,并折算出PH值的方法。
