  • Gravity vs. Vacuum FiltrationPhysics Forums

    Feb 20, 2007Gravity filtration is more useful for filtering gel type substances like nickel DMG. Vacuum filtration is usually performed with a filter aid such as diatomite. The real advantage for the filter aid/vacuum filtration is in the filtration of very small particles such as decolorizing carbon.

    Choose a filter paper suitable for the particle size of the precipitate. Vacuum filtration rather than gravity filtration is suitable for the separation of a precipitate consisting of light and fine particles. Unless the filter paper tightly sticks to the funnel, air comes into the funnel leg, and the filtration speed decreases.
