Rotary Evaporators are used to distill solvents from compounds with precise evaporation. These are especially useful when trying to separate organic compounds from ethanol, or any other low boiling point solvents. Boiling points can be lowered by pulling a vacuum on the system. The evaporating flask rotates with variable speeds, allowing you to spin the solution into a thin film around the flask. With a combination of a reduced pressure and large heating surface area, these are great for quick distillation. Internal glass coil condenser cools solvent vapors, allowing them to fall into the collection flask. This leaves you with distilled solvent, ready to use again. The heating element is controlled by a PID controller, accurate to the degree. Slowly raise temperatures to achieve your solvent's boiling point without disturbing the extract.
