BUCHNER FUNNEL

A Büchner funnel is a specialized piece of laboratory glassware used for vacuum filtration. It is designed to facilitate the separation of solids from liquids by creating a vacuum-driven filtration process. The funnel typically features a flat, perforated base, which allows for efficient flow of liquid through a filter paper placed on top. The funnel is connected to a vacuum source via a side arm, which helps in drawing the liquid through the filter and accelerating the filtration process.

Made from durable materials such as borosilicate glass or porcelain, Büchner funnels are resistant to chemical reactions and thermal stress. They are often used in conjunction with a vacuum flask or a filtration assembly to collect the filtrate. Büchner funnels are essential in applications such as purifying compounds, separating precipitates, and performing solid-liquid extractions in chemistry and biological laboratories.
