The reason for the use of fluted filter paper in gravity filtration should be explained. Concept introduction: Gravity filtration is the process that is used to separate the solids from liquids based on the particle size with the help of gravity. This method is used when the filtrate is to be retained and the residue on the filter paper is discarded. It includes the use of conical flasks, fluted filter paper, stemless funnel, and boiling chips. It is a slow process and removes only large particles from the air.
