A rotary evaporator (or rotavap [1] / rotovap ) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase rotary evaporator, though use is often rather signaled by other language (e.g., …

A rotary evaporator (rotovap) is a fast and effective method of removing solvent from a flask. A rotovap removes solvent by reducing the pressure within the flask using a vacuum, rotating the sample to increase its effective surface area, and heating the solution.

A rotary evaporator (sometimes abbreviated to rotavap) is a piece of equipment primarily used to remove solvent from a sample through “evaporation under reduced pressure”. The presence of reduced pressure in the apparatus causes the solvent (in the round bottom flask) to boil at a lower temperature than normal.

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.

Feb 25, 2021 What is Rotary Evaporation? Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.

Important Features of the Rotary evaporator. 1) The vacuum pump is the source of reduced pressure in the system. 2) Spin speed and bath temperature control knobs. 3) Water bath. 4) Bump guard. 5)Cold finger (Please do not use the rotavapor if the finger is not cold. There should be excess solid dry ice in the finger). 6)Vacuum release valve.

Laboratory equipment Rotary evaporator is mainly used for continuous distillation of a large number of volatile solvents under reduced pressure conditions. In particular, the reaction product can be separated and purified by the concentration of the extract and the distillation of the liquid...

Nov 11, 2021 Rotary evaporators exploit this pressure-boiling point dependency and operate at a lower pressure, meaning you can boil liquids at a reduced temperature and without oxygen. This is crucial for mixology, and allows for a gentler distillation and avoids oxidation. The rotary evaporator was first commercialised in 1957 by Bchi for use in ...

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.

Sep 24, 2014 Rotary evaporators are primarily used to continuously distill large amounts of volatile solvents under reduced pressure. In particular, the concentration of the extract and the distillation of the receiving liquid in the chromatographic separation can separate and purify the reaction product.
