A buchner funnel (Büchner funnel) is a piece of laboratory equipment used in filtration. It is traditionally made of porcelain, but glass and plastic funnels (PTFE bucher funnel) are also available. On top of the funnel-shaped part there is a cylinder with a fritted glass disc/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 of a Hirsch funnel is much smaller, and the walls of the funnel angle outward instead of being vertical.
