Contact SupplierFunnels can be made of borosilicate glass. However, glass is a preferable material, due to its resistance to chemical reactivity. A funnel consists of two main parts: a conical-shaped top and a long cylindrical stem at the bottom. Funnels are used for transferring liquids to containers with small openings, in order to prevent spills. They can also be used with filter paper in the process of filtration. Funnels come in many different sizes, depending on the amount of material being poured through.
