9. Chose a temperature appropriate for the solvent being evaporated. Lower temperatures make for a slower evaporating process but reduce the likelihood of bumping. 10. For higher boiling solvents, check to see if your solvent can be combined with another to form an azeotrope that has a lower boiling point. 11. Boiling is not the same as bumping.

Azeotropes in Rotary Evaporation Blog

Azeotropes in Rotary Evaporation Blog

Jun 21, 2021 A zeotropic mixture is a combination of solvents that don’t form an azeotrope when combined in any proportion. For example, acetic acid and water never form an azeotrope. Due to the similar boiling points of these two liquids (acetic acid has a boiling point of 118.1C), it is difficult to separate them using distillation alone.

Rotary Evaporator (Rotovap) Issues and the Smart Solution

Mar 11, 2019 Small Sample Sizes (Painstaking vs. Painless) Working with rotary evaporators can be difficult, especially with small samples. Transferring the solvent to the rotovap, followed by painstakingly scraping the sample from the round-bottom flask, not only leads to wasted effort, lost time and loss of sample, but also presents risk of cross-contamination.

Optimal Distillation parameters for a rotary evaporator vary according to solvent in use: 1. Set water bath temperature to 60oC – It does not need to be higher! 2. The cooling water temperature should be below 20oC. 3. Adjust the needed vacuum for a solvent boiling point of 40oC according to list below. Reference: Buchi: List of Solvents
