One of the most common methods of recovering solvent from hash in the lab is with a rotary evaporator. This distillation apparatus operates under vacuum to reduce the boiling point of the solvent, allowing us to evaporate off our solvent without damaging the cannabinoids, at much lower temperatures. The boiling flask rotates to create a thin film, which speeds up the evaporation. After the solvent is evaporated, and is traveling towards the vacuum pump in the vapor stream, it passes over the c…
