Introduction：

A funnel is a barrel-shaped object that is used to pour liquid and powdery matter into a container with a smaller inlet. The smaller tubular part at the tip of the funnel can have different lengths. Funnels are usually made of stainless steel or plastic, but paper funnels are sometimes used for substances that are difficult to clean thoroughly, such as engine oil. Some funnels have a controlled valve in the nozzle, allowing the user to control the flow rate.

Advantage:

1, The long neck funnel has a very long neck and is very simple to operate. The long neck funnel can be added at any time during the reaction process. The long neck funnel must be inserted below the liquid level to prevent gas from escaping through the bottom of the long neck funnel when it is formed, that is, to form a liquid seal.

Pay attention：

1,把滤纸,主要用于过滤e. When using, pay attention to the end of the funnel only against the inner wall of the beaker to prevent the filtrate from bursting. Filter paper wet with water only against the funnel wall, do not leave bubbles. The filter paper should be lower than the edge of the funnel, and the filtrate should be lower than the edge of the filter paper to prevent the liquid not filtered from the gap and the effect of filtration. Note that a glass rod should also be used to drain the filter to prevent it from bursting or breaking through the filter paper. The glass rod should be placed on the three layers of filter paper to avoid breaking the filter paper and affecting the filtering effect.
