Buchner Funnel, 90 mm, porcelain

A Buchner funnel is used for vacuum filtration. This porcelain Buchner funnel is 90 mm diameter and has a capacity of about 200 ml. The filter platform has dozens of small holes (about 1/8') to provide filtration efficiency. The stem tapers from about 22 mm OD at the end to 30 mm OD at the cone. Porcelain is durable, acid and alkali resistant, easy to clean and autoclavable. This Buchner funnel can be used with a vacuum filtration flask and a rubber stopper of the correct size to fit the flask (not included). Be sure to order with 11 cm filter paper, which will need to be cut down. The one-piece design of the porcelain 90 mm Buchner funnel is perfect for vacuum filtrations.
