A funnel is a tube or pipe that is wide at the top and narrow at the bottom, used for guiding liquid or powder into a small opening. Funnels are usually made of glass. The material used in its construction should be sturdy enough to withstand the weight of the substance being transferred, and it should not react with the substance. There are many different kinds of funnels that have been adapted for specialised applications in the laboratory. Filter funnels, thistle funnels (shaped like thistle flowers), and dropping funnels have stopcocks which allow the fluids to be added to a flask slowly. For solids, a powder funnel with a wide and short stem is more appropriate as it does not clog easily.
