As a manual process blow down evaporation requires continuous monitoring by the user to detect the end point of the drying process. The technique typically achieves poor final dryness and splashing may occur, particularly if the gas flow rate is too high, leading to sample cross-contamination. Vortex and Rotary Evaporation

Aug 15, 2021 Advanced techniques; Contributors; Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components ...

In a typical procedure, a thin film formed from 25 mg of DOPC in 20 mL CH 2 Cl 2 in a 50-mL evaporation flask is rehydrated with an aqueous solution of 1 M CaCl 2 (5 mL). Rehydration and agitation are performed by gentle spinning of the evaporation flask in the water bath (40 C) of the rotary evaporator, without vacuum.

Rotary evaporators: A rotary evaporator is used to remove a solvent fr om a flask without having to heat that flask to the boiling point of the solvent at one atmosphere. This has the advantage that it is quicker and is less likely to cause thermal decomposition to the sample. All the rotary evaporators are connected to a source of vacuum.
