When the difference in boiling points is less than \(100^\text{o} \text{C}\), a modification is necessary, namely insertion of a fractionating column between the distilling flask and three-way adapter (Figure 5.37a). DURAN, borosilicate glass 3.3, clear.The distillation columns are essential parts in apparatuses when separating mixtures based on volatilities. Glass beads have a high surface area, so are a good choice for separation of close-boiling components. Lastly, a spin bar has to be added to the flask to mix the solution during the distillation.

Several distilling columns shown from left to right Hemple. A simple distillation is incapable of significant purification if the boiling points of the components are too close. Both top outer and lower inner joints are the same size. Your session has expired. The setup affords a significant amount of space (~1/2 fume hood) and therefore should be place on one side of the fume hood and not in the middle. And yet, beads will suffer the greatest loss of material. Glass bead column: rinse with acetone, then replace the glass wool wad to prevent the beads from pouring out when horizontal.
