For ethanol extraction with dry ice, a rotary evaporator with a cold finger glass condenser is ideal. A coldfinger configuration is common for the production of tinctures, yielding a thick concentrate that is considerably pure with relatively little solvent use.

Rotary Evaporation to Remove Solvent | Protocol

Rotary Evaporation to Remove Solvent | Protocol

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.

Dec 18, 2018 · The most common way to make a cold-finger is to mix isopropyl alcohol and dry ice. Dry ice needs to be added continuously, but it's not cold enough to freeze the alcohol and, unlike ice, it evaporates into gas when it is spent. Simultaneous to all of the above, the flask is placed into a heated water bath and rotated continuously.

Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts.. A simple rotary evaporator system was invented by Lyman C. Craig. It was first commercialized by the Swiss company Büchi in 1957. In research the most common form is the 1L bench-top unit, whereas large scale (e.g., 20L-50L) versions are used in pilot plants in commercial chemical operations.
