General Description
Similar to the standard one-piece design with the added efficiency of water-cooled jacketing. Water-cooled jacketing efficiently condenses volatile heat-sensitive compounds.
Falling Film Technique
1. Flask A is filled with the solvent desired and heated to reflux. The boiling solvent vapor maintains a constant temperature at the center finger. The temperature is the boiling point of the solvent.
2. The material to be distilled is placed in the addition funnel and allowed to drip slowly onto the heated center finger. The volatilized material will condense on the outer air-cooled wall and collect in Flask B. The high boiling material will remain on the center finger and flow down the spiral into Flask C.
3. Any pressure-equalizing funnel, standard condenser, and flasks can be used.
