A rotary evaporator, or rotovap for short, is a piece of high-end equipment found in chemical laboratories. Since they are costly, they are usually out of reach for amateur chemists. However, a rotovap is not difficult to build. In this video, I show you how I built my own rotovap for a fraction of the price of a commercial rotovap.

Errata: It's a reflux condenser, but does not return the condensate to the system from which it originated. It just cools the vapor, which condenses and drips in the flask below the condenser. So it's not a reflux process.
