Filter paper
From Academic Kids
Filter paper is any of various grades of coarse unfinished paper which can be used to separate solids from a liquid in which they are suspended. The filter paper is usually fitted into a filter funnel or Buchner funnel to provide mechanical support. The suspension is then poured into the filter paper. The force of gravity and capillary action draw the fluid through the paper, leaving the solids behind. Vacuum is also used to force the fluid through the paper.
