An advantage & feature of a buchner funnel is that it can use vacuum suction for filtration rather than a gravity-powered simple filter funnel to proceed filtration more quickly. A technique to collect recrystallized compounds is commonly used in organic chemistry. Assembling the buchner funnel usually involves attaching it to a filtering funnel and connecting the side hose to a vacuum source, adding a rubber buchner flask adapter and the vacuum pump, and connecting it to vacuum The filtration device is not recommended for applications requiring pressures in excess of 15 psi.

Dimensions-----The top of the funnel is covered by a glass frit disc plate with a pore diameter between 10 and 20 microns. An outer diameter of 10mm is measured on the frit disc plate. Ten milliliters of fluid can be stored in the cylinder.

This is a good funnel, but please find a way to expedite the shipping time
