Product Description
A Buchner funnel is a porcelain funnel with a flat, perforated bottom. This funnel is used only for vacuum filtration. A holed rubber stopper or adapter is needed to hold the funnel in place inside the neck of a suitably-sized filter flask. When the side-arm of the filter flask is attached to the aspirator (or to a vacuum trap attached to the aspirator), any liquid poured into the top of the Buchner funnel is quickly sucked into the flask, ideally leaving any particulate matter or precipitate on the filter paper inside the funnel. Any precipitate can then be effectively air-dried simply by leaving the vacuum connected, drawing air through the precipitate. Sizes may vary.
