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，长颈漏斗的脖子很长，非常易于操作。在反应过程中，可以随时添加长颈漏斗。长颈漏斗必须插入液位以下，以防止形成时气体通过长颈漏斗的底部逸出，即形成液体密封。

Pay attention：

1,Put on the filter paper, mainly for filtering use. 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.
