Filter Setup w/1000mL Glass Flask, 110mm Buchner Funnel, Stopper and Filter Paper

With its 1000mL borosilicate glass filter flask and 110mm (inside diameter) porcelain buchner funnel, this filtration setup is perfect for use in vacuum filtration. Filtration is a technique by which a solid product is separated from an aqueous solution by pulling the liquid through the filter paper. In this setup, a piece of 11cm filter paper is placed in the buchner funnel, and allows the filtrate (liquid) to pass through into the flask, while the precipitate remains on top of the paper. A custom drilled rubber stopper is included with this setup to hold the funnel in place above the flask.

By using a vacuum hand pump (not included) or a vacuum system (not included), the filtrate is much more easily separated from the precipitate, by pulling as much liquid through as possible. There will be some moisture left in the sample, so it is advisable to allow the sample to dry completely before using it in your application. Using a vacuum rather than gravity filtration allows for a variable filtration rate based on the strength of the pump being used, though care must be taken to not use a vacuum strong enough to rip the filter paper or break the flask. This setup is capable of performing gravity filtration in the absence of a vacuum pump or system.

The 11cm qualitative filter paper may need to be wetted lightly to fit into the buchner funnel.
