The Büchner funnel is a specialized laboratory tool designed for efficient filtration under vacuum. Typically made of durable porcelain, plastic, or polypropylene, it features a flat, perforated plate that supports filter paper, allowing for rapid separation of solids from liquids. Ideal for chemical, biological, and analytical labs, this funnel is commonly used in conjunction with a vacuum flask and vacuum source to speed up the filtration process compared to gravity filtration.
Its robust design ensures compatibility with a wide range of laboratory chemicals and solvents, while the rigid structure maintains stability under suction. Available in various diameters to suit different filtration volumes, the Büchner funnel is an essential component for laboratories requiring precise, efficient, and repeatable filtration results.
