Distillation of high-boiling solvents

When working with rotary evaporators, the separation of high-boiling solvents such as DMSO or DMF is often difficult. The substances tend to condense again in the vapor tube and are therefore difficult to transfer into the receiving flask. Three things are especially important in this case: An absolutely leak-proof rotary evaporator system, a powerful vacuum pump and a glassware suitable for separating high-boiling substances.

The following configurations are particularly suitable for the distillation of high-boiling substances: For small quantities, choose a benchtop rotary evaporator with a diagonal glass set and a speed-controlled pump. The Hei-VAP Industrial - All-round package is suitable for large quantities.
