** Filtering with a Small Funnel [25]

In filtering a large amount of solution one usually desires some
means other than a large funnel and something to make the watching
of the process unnecessary. If a considerable quantity of a
solution be placed in a large bottle or flask, and a cork with a
small hole in it inserted in the mouth, and the apparatus
suspended in an inverted position over a small funnel so that the
opening of the cork is just below the water level in the funnel,
the filtering process goes on continuously with no overflow of the
funnel.

As soon as the solution in the funnel is below the cork, air is
let into the flask and a small quantity of new solution is let
down into the funnel. The process works well and needs no
watching, and instead of the filtrate being in a large filter
paper, it is on one small piece and can be handled with ease.
