Description
A porcelain Büchner funnel is a laboratory filtration device made from high-purity ceramic (porcelain) and designed for vacuum filtration. It typically consists of a cylindrical body with a flat perforated plate at the bottom, where filter paper is placed. The funnel is placed over a filtering flask and used with a vacuum source to rapidly separate solids from liquids.
