Buchner Funnel 2000 ml Porcelain with 186 mm Plate Diameter CoorsTek

The CoorsTek 60247 Buchner Funnel is a piece of laboratory equipment designed for vacuum filtration, a method used for the rapid separation of solids from liquids. This funnel has a large capacity of 2000 ml (2 liters), making it suitable for filtering substantial volumes of mixtures.

It is constructed from porcelain, a material known for its chemical inertness, high thermal stability, and mechanical strength, which allows the funnel to be used with a variety of solvents and to withstand the stresses of the vacuum. A key dimension is the 186 mm plate diameter, which refers to the inner diameter of the perforated plate where the filter paper rests. This large diameter provides a wide surface area for the precipitate, ensuring efficient and fast filtration.

The Buchner funnel is used by placing a piece of filter paper over the perforated plate and connecting the stem to a filter flask (Büchner flask) via a rubber stopper or adapter, which is then connected to a vacuum source. The CoorsTek 60247 is an essential tool in chemistry and biology laboratories for collecting solid precipitates and preparing samples for further analysis.
