Jan 18, 2017 · When operating a rotovap, following tips should be remembered. To remove algae gunk from the inside of a coiled water condenser, the condenser has to be removed from the rotovap and the coil is soaked in a dilute nitric acid solution for a few hours. After carefully rinsing the insides, the rotovap is reassembled.

The rotary evaporator functions on the general assumption that the boiling point of the solvent is much lower than that of the liquid surrounding it. It also assumes the compounds in the liquid are thermally sensitive; otherwise you could just boil the solvent out. A rotovap works by creating a vacuum in a rotating glass flask.
Learn More
The rotatory evaporator working principle is that the boiling point of liquids lowers on decreasing their pressure. This allows the solvent to vaporize at lower temperatures than when boiled in a normal atmosphere. You should choose a vacuum pump for your rotavap that will guarantee an improved evaporation efficiency.
