Rotary evaporator De Qumica

Although this operation could, in principle, be performed by simple distillation, the fastest and most convenient method is the use of a rotary evaporator (rotovap) for distillation under reduced pressure. Basically, it consists of an electric motor, which causes the rotation of a tube attached to a ground glass-oint guide tube.

What is a Rotary Evaporator?

Feb 14, 2022 How Does a Rotary Evaporator Work? Rotary evaporators work on the principle that solvents have a range of boiling points, which decrease under reduced pressure. The evaporation flask rotates at a specified speed forcing the materials to form a large area of thin film on the inner wall of the flask.

Rotary Evaporation - an overview ScienceDirect Topics

Rotary evaporation: Solvent is removed at reduced pressure by mechanically rotating a flask in a controlled temperature water bath. Condensed solvent is collected in a separate flask: Volatile compounds are typically lost. Recovery of less volatile material may be lower than expected due to entrainment of the analyte the solvent vapor.
