Rotary Evaporation Techniques For Higher-Quality Cannabis .

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 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: heat bath, rotor, condenser, and .
