Advanced Solvent Removal without Rotovaps Podcast

In a nutshell, solvent removal is necessary to recover, or remove solvent from CBD oil after ethanol extraction or winterization. This is accomplished by applying vacuum pressure and heat to a thin film of oil causing it to evaporate from the oil before condensing and collecting in a receiver flask, or other capture vessel.
