Rotary Evaporation - Chemistry LibreTexts

Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and .

Rotary Evaporator (Rotovap) - Dartmouth College

The rotary evaporator is the method of choice for solvent removal in the modern organic laboratory. The solvents or low boiling compounds are removed by a simple distillation. The rotovap is designed to be operated under a vacuum (to lower a compound's boiling point) while heating the sample at .


Nov 29, 2004 · Commercial evaporation of orange juice began in the late 1940's. The first evaporators, to produce a product to be reconstituted and used as orange juice, were low temperature-high vacuum evaporators designed and built by B.C. Skinner of Dunedin, Florida. There were several evaporators built on this basis (Frostproof, Auburndale, Dunedin).

Vacuum distillation - Wikipedia

Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve or will cause the compound to decompose.

Flash evaporation - Wikipedia

The flash evaporation of a single-component liquid is an isenthalpic process and is often referred to as an adiabatic flash. The following equation, derived from a simple heat balance around the throttling valve or device, is used to predict how much of a single-component liquid is vaporized.

TSPS Engineering Manual

In a flash type evaporator, heated salt water passes through an orifice into an area of lower pressure which is created by an air ejector or vacuum pump. A portion of the water flashes into steam, and the steam passes up to a vapor separator, where water droplets are removed, and then to a distilling condenser where the vapor is condensed.

Flash Column Chromatography Guide - MIT OpenCourseWare

- Flash Column Chromatography Guide Overview: Flash column chromatography is a quick and (usually) easy way to separate complex mixtures of compounds. We will be performing relatively large scale separations in 5.301, around 1.0 g of compound. Columns are often smaller in .

How to use a Rotary Evaporator

A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. 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.


The rotary evaporator or "rotovap" is an expensive piece of apparatus that needs to be used with great care. If you follow the instructions carefully, it is the fastest, most efficient and most environmentally friendly way of removing a volatile solvent from a non-volatile sample. It is standard equipment in a modern chemistry laboratory. The .

Rotary evaporation can separate solvent from different types of mixtures and materials but it is crucial that the desired compound has a higher boiling point than the solvent. Lower boiling point solvents work best, but rotary evaporation is more commonly used to remove water (b.p. 100 ˚C).
