How to use a Rotary Evaporator

Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

Apr 04, 2019 Ideally, a pump used in a rotovap setup should be oilless and chemical-resistant to make sure it lasts as long as possible. The most commonly used pumps for this purpose are diaphragm (or membrane displacement) pumps. A variety of pumps (from left to right): an ME1 Diaphragm Pump, a VP Series Vacuum Pump, and a MVP 10 basic Vacuum pump.

Apr 04, 2019 That is, your chiller should be able to provide a coolant stream that is at least 20C below the boiling point of your solvent. You may be tempted to set the temperature far below that to increase the speed of condensation. However, this can be counterproductive as cooling capacity decreases at lower temperatures.

It is a good idea to cool the receiving flask (e.x. solvent reservoir); it prevents any solvent from evaporating from the receiving flask, especially for low boiling solvents (e.g. pentane). Connect the bump trap to the rotovap and secure with the metal clip or a keck clip depending on the model of rotovap (pictured below).

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.
