Fractional distillation template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
Flask in a heating mantle, Vigreux column, still head with the thermometer bulb at the side arm, water condenser, adapter and receiver. GCSE / A-level / university.
What the template shows
- Separate liquids with close boiling points on a fractionating column
- Water out
- Bulb level with the side arm; steady while each fraction distils
- Vigreux column
- Vapour condenses and reboils on the glass many times, so it gets richer in the more volatile liquid. Wrap in foil to insulate; a packed column (glass beads) also works
- e.g. cyclohexane and toluene; boiling chips; heat slowly
- Holds the receiver by the neck
- Change it when the temperature rises to collect separate fractions
- Reaction setup
Drawn with 20 shapes – every one editable in MolDraw.
