Rotary Evaporation Techniques For Higher-Quality Cannabis .

As the pressure is reduced using a vacuum pump in the rotary evaporator, the boiling point of the solvent, ethanol in this case, is lowered. Typically, the distilling flask (A) is filled to 50% volume. The water bath (B) is heated to 30-40°C. The condenser temperature (F), controlled by a recirculating chiller, is set to -10°C to 0°C.

Rotary evaporator - Wikipedia

A rotary evaporator is often used with a water bath. A rotary evaporator works by reducing the pressure over a solution using a vacuum pump, thereby reducing the boiling point of the liquid. As the liquid evaporates quickly, it pulls heat from the solution. That heat needs to be replaced so the evaporation does not stop.
