Introduction to Buchner Funnel
A Buchner funnel is a laboratory apparatus used in filtration processes. It is typically made of porcelain, glass, or plastic and has a flat, perforated plate at the bottom. The funnel is used in conjunction with a filter flask and a vacuum source to separate solids from liquids. The liquid passes through the filter paper placed on the perforated plate and into the flask, while the solid remains on the filter paper. Buchner funnels are widely used in chemical, pharmaceutical, and biological laboratories for various filtration applications, such as the purification of chemicals, the isolation of precipitates, and the clarification of solutions.
