How It Is Used
The liquid mixture is heated in the round-bottom flask and its vapour climbs the Vigreux column, where the components separate according to boiling point. Vapour leaving the column is cooled in the Liebig condenser, and the condensed fraction runs through the receiver adapter into the Erlenmeyer flask.
