漏斗作为一种实验仪器，在化学实验中一般用于过滤操作，及向某一容器中加注液体。除此之外，漏斗“大口细颈”的结构特点还决定了它在化学实验中具有特殊的用途，如１９９８年高考实验题（第２７题）中的漏斗就是作为一种集气装置出现的。在此仅对漏斗在化学实验中的特殊用途
The funnel is used as an experimental instrument and is generally used in chemical experiments for filtration operations and the addition of liquid to a container. In addition, the structural characteristics of the funnel “big mouth and neck” also determine its special use in chemical experiments. For example, the funnel in the 1998 college entrance examination experiment (question 27) was used as a gas gathering device. . Here only the special use of the funnel in chemical experiments
