Choosing the right Rotary Evaporator for your lab

Dec 08, 2021 In a rotary evaporator, the motor rotates the evaporation flask or vial containing the user’s sample. Vapor duct is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample. The vacuum system substantially reduces the pressure within the evaporator system. The system can be as simple as a water aspirator with …

Jun 06, 2016 First take your sample solution (in round bottom flask—volume half full) to the rotovap you wish to use. A bump trap (located in the drawer next to the rotovap hood) should be placed between the rotating vapor duct and your flask of sample solution (Keck clamps should also be equipped for the ground glass joints).

Evaporation with nitrogen - Chromatography Forum

Jun 22, 2010 by Lorespain Mon Jun 21, 2010 4:15 pm. Hello! I am working in the detarmination of lipo-soluble vitamins and I have a problem with the evaporation of the solvent (hexane) after extraction. I am using a flow of nitrogen because I haven't got rotavapor, and the evaporation takes about 5 hours. The volum I have after the extraction is about 100 ml.

Solvent Removal

Make sure the vent at the top of the cooling coils is closed. Turn the vacuum outlet on the vacuum system on. As the solvent evaporates, you may notice a lot of frothing and bubbling in the evaporating flask. If it starts bubbling out of the flask, you can open the vent a little (see picture above) to release some of the pressure.
