Buchner Funnel
A Buchner Funnel is a fritted/perforated funnel used in laboratories for the vacuum-assisted filtration and separation of liquid substances. Buchner Funnels allow you to filter liquids by pulling them through qualitative paper and perforations at the highest of the funnel using a pump.
These funnels are glazed inside and outside, with the exception of the rim, and are without a cover. These are autoclavable and highly resistant to chemical attack. Material: Porcelain
It is used with the filtration technique Standard taper inner joint lower outlet with 0-4mm high vacuum valve Top outer joint and lower inner joint is of the same size Sidearm has 2mm glass stopcock with constant temperature retention device&...
With sealed in glass disc of the specified porosity. Not recommended for filtration where pressure would exceed 15psi. C-Coarse, M-Medium, F-Fine porosity.
With sealed-in perforated glass disc to support filter media. Pressure may be used but should not exceed 15psi. This design solves the contamination problem with fritted disc and also the blindness problem with ceramic Buchner funnel.
With lower standard taper inner joint and sealed-in perforated glass disc to support filter media. The hose connector on the side arm is connected through a vacuum source. Pressure may be used but should not exceed 15psi.
Buchner filter funnels have a jacket that covers the entire funnel bowl as well as the upper section of the stem. During filtering, liquid circulation through the jacket allows the funnel and contents to be warmed or cooled. They come in coarse (C...
