Heidolph Instruments : Large-Scale Rotary Evaporators
· Rotary evaporators allow many configurations depending on the use. A diagonal glass condenser is common for standard distillation of non-volatile substances. Vertical class condensers allow solvents with higher boiling points. For ethanol extraction with dry ice, a rotary evaporator with a cold finger glass condenser is ideal. Rotary evaporation is a powerful technique for quickly removing solvent from a solution of cannabis or hemp extract. There are two distinct methods of operating a rotary evaporator: batch or continuous; choosing the correct one for the task is crucial.

Rotary Evaporator Procedure / Process - Rotovap - WKIE …
If it is necessary to evaporate volumes of solvent greater than the capacity of the rotating flask, you can carry out the process batch-wise involving several separate evaporations or the rotary evaporator can be modified for continuous evaporation (Fig. 17.2). Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

Evaporator - an overview | ScienceDirect Topics
Lower boiling solvents work best, however, rotary evaporation is commonly used to remove water. Higher boiling solvents such as DMF and DMSO are more easily removed using other techniques such as lyophilization, however, with a very good vacuum pump, they may be removed using rotary evaporation. A rotary evaporator for laboratory scale solvent evaporative procedures is described. A magnetically driven fluorocarbon coated rotor, operating within a container for solvents, creates a thin film for rapid solvent evaporation without the usual requirement for rotating the entire solvent container assembly. Rotary seals are eliminated, increased control over bubbling and foaming at higher ...

How does rotary evaporation work? - Lab Instrument ...
Rotary Evaporators. Removal of solvents by simple distillation is a tedious procedure, complicated by setup and cleaning of the apparatus. A major advance in efficiency is achieved by using a rotary evaporator ("rotovap"). This cuts the distillation time for eliminating ether from a couple of hours down to 20 minutes or so. The Rotary evaporator is a common laboratory apparatus used for quick removal of solvents from reaction mixtures. This is done by heating mixtures gently under reduced pressures to accelerate the rate of evaporation. A vacuum evaporator used to work by bringing down the pressure over a mass of fluid, thus reducing the boiling points.

A typical example is the rotary evaporator that uses adequate pressure to get as close as possible to the solvent's boiling point and to evaporate solvents at low temperatures (fig. 1). With pressure being too high, evaporation will take too long and with pressure being too low, substance may start foaming. A rotary evaporator is a device commonly used in chemical laboratories for the efficient and gentle removal of the volatile solvents from samples by evaporation. They are found in …
