Do you know that?/You know what? Do you know that?/You know what? In chemical experiments, filtration and evaporation operations are very common steps. These operations are inseparable from some utensils, such as beakers, funnels, iron shelves, glass rods and so on. This article will introduce the functions and usage of these artifacts for you, so that you can become a small expert in the laboratory.

Artifact of filtering operation

Beakers, funnels and iron frames are essential tools in filtration operation. The beaker is used to hold the liquid to be filtered, the funnel is used to filter, and the iron frame is used to support the funnel. In addition, the glass rod is also a very important tool, which can be used to drain water and prevent liquid from overflowing.

Artifact of evaporation operation

In the evaporation operation, alcohol lamp, evaporating dish and glass rod are essential tools. Use alcohol lamp to provide heat source, use evaporating dish to hold the liquid to be evaporated, and use glass rod to prevent the liquid from splashing. The cooperation of these tools can make the evaporation operation safer and more efficient.

Become a little genius in the lab

Learning these little knowledge of chemistry can make you better master the skills of filtration and evaporation and become a master in the laboratory. In the experiment, the correct use of these utensils can not only improve the efficiency of the experiment, but also ensure the safety of the experiment.
