Definition : Funnels that are made of glass and fitted with a stopcock to control the flow of fluids being transferred between the funnel and a flask, such as when adding reagents slowly, drop-by-drop, to a solution. Some dropping funnels have an additional narrow-bore glass tube intended to equalize the pressure between a receiving flask and the funnel. Dropping funnels are used in medical and/or clinical laboratories.
