Here’s how the Büchner funnel with a fritted disc is typically used:
- Setup:
- Place the Büchner funnel on a filter flask.
- Connect the filter flask to a vacuum source, creating a vacuum below the fritted disc.
- 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.
- 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.
- Collection:
- The filtered liquid collects in the filter flask, while the solid residue remains on the filter paper or in the filter crucible.
- Cleaning:
- After filtration, turn off the vacuum source and carefully remove the filter paper or filter crucible with the collected solid.
