Remove and clean the bump bulb from the rotovap immediately after use to ensure ground glass joint connections do not stick together and to prevent contamination of future samples that will be rotovaped.

Operation of the Rotary Evaporator (Rotovap)

However our system will only work for solvents that would normally boil at temperatures less than 60C at atmospheric pressure. The rotovap itself consists of the following parts: a) a long condenser containing a distillation tube surrounded by a coil of glass tubing. This glass tubing will have cold water running through it to provide a ...

IV. How Rotary Evaporation Works Here is the basic rotary evaporator setup. We’ll go into greater detail on some of these parts in Section VI. And here’s what happens during distillation: V. Some General Theory Before getting into greater detail on the rotovap process, it is important to understand the theory behind the instrument.

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...
