Here’s how the Büchner funnel with a fritted disc is typically used:

  1. Setup:
    • Place the Büchner funnel on a filter flask.
    • Connect the filter flask to a vacuum source, creating a vacuum below the fritted disc.
  2. Filtration:
    • Prepare a filter paper or filter crucible and place it on the fritted disc.
    • Pour the liquid containing the solid particles into the Büchner funnel.
  3. Vacuum Filtration:
    • Turn on the vacuum source.
    • The vacuum created beneath the fritted disc pulls the liquid through the filter medium, leaving the solid particles on the filter paper or in the filter crucible.
  4. Collection:
    • The filtered liquid collects in the filter flask, while the solid residue remains on the filter paper or in the filter crucible.
  5. Cleaning:
    • After filtration, turn off the vacuum source and carefully remove the filter paper or filter crucible with the collected solid.
