Fractional distillation is carried out using a FRACTIONATING Column . It is usually consist of long glass tube with a wide bore either packed with glass beads , small stones , porclain rings or coke or brown into a number of spherical or pear - shaped bulbs .
The actual purpose of FRACTIONATING Column is to increase the cooling surface area and to provide hurdle or obstructions to the ascending vapours and descending liquid .
