How to use a Rotary Evaporator

How to use a Rotary Evaporator

Apr 01, 2010 This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal. Most labs use a simple water aspirator vacuum on their rotavaps, so a rotavap cannot be used for air and water-sensitive materials unless special precautions are taken i.e. …

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).

Mar 02, 2020 The answer is “YES”. A rotary evaporator can remove solvent by evaporating samples through the continuous rotation of the evaporation flask. Meanwhile, the evaporation flask is heated uniformly by a water bath. Then the material with a lower boiling point can be evaporated quickly under negative pressure.

Rotary Evaporation to Remove Solvent Protocol

Rotary Evaporation to Remove Solvent Protocol

Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or rotovap, was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications.

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.

Roto-evaporation requires mechanical rotation of a flask under vacuum. The rotation of the flask increases the surface area of the solvent to be removed, increasing the rate of evaporation, and reducing the risk of bumping: when a large pocket of solvent vapor forms rapidly and displaces the surrounding liquid.
