  • Description: A B├╝chner funnel is a piece of laboratory equipment used in filtration.[1] It is traditionally made of porcelain, but glass and plastic funnels are also available. On top of the funnel-shaped part there is a cylinder with a perforated plate separating it from the funnel. The Hirsch funnel has a similar design; it is used similarly, but for smaller quantities of material. The main difference is that the plate is much smaller, while the walls of the funnel angle outward instead of being vertical. This sign video was contributed by users of the ASL-STEM Forum:
