What are rotary evaporators? A rotary evaporator (or rotavap or rotovap) uses precise engineering to effectively remove solvents from a sample using evaporation. Most rotovaps make use of a vacuum and pressure control monitor to precisely control pressure within your system, increasing evaporation .

Concentrating heat sensitive samples without degradation .

At reduced pressure, the evaporation phase change occurs at a lower temperature, allowing the sample to be concentrated without damage from excessive heat. Common laboratory methods for solvent evaporation or sample concentration are lyophilization (also known as freeze drying), vacuum evaporation, nitrogen blow down and rotary evaporation.

Across International SolventVap Rotary Evaporators | The .

These rotary evaporators feature a specially designed motor and worm gear, which provides constant rotation at varying speeds. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface.

The Lab Depot | Pumps

Vacuum manifolds are commonly used for the final drying of samples removed from a rotary evaporator. Organic solvents and/or acids left behind during the distillation process are removed over several hours or more depending on the sample size. A foreline cold trap is always recommended to minimize the ingestion of the solvents.

The "Golden Rule" for Solvent Removal When Using a Rotary .

An easy concept to remember for solvent removal by a rotary evaporation is the 20/40/60 Rule. 20/40/60 Rule. The vacuum is adjusted properly for each solvent with an operating bath temperature of 40 ℃ which is subsequently condensed at 20ºC. The rule can be applied to lower bath temperatures too, e.g.: Cooling water: 0ºC; Vapor: 20ºC; Bath .

Rotary Evaporators - Across International

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate "low boiling" solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure.

The "Golden Rule" for Solvent Removal - Sigma-Aldrich The "Golden Rule" for Solvent Removal S olvent removal remains an unavoidable process that scientists and engineers must perform on scales ranging from a few milliliters to thousands of liters. The use of a rotary evaporator in this process has become ubiquitous for single batch and continuous processes.

Rotary Evaporator Only Information

The water bath temperature should not exceed the boiling point of the solvent! • The condenser could be overloaded since the evaporation rate will exceed the condensation capacity. . • A solvent table, below, from a large rotary evaporator manufacturer, Buchi.

The Rotary Evaporator

We take advantage of this in our use of the rotary evaporator or rotovap. The diagram below is a generic rotary evaporator. The essential parts are shown. The rotary evaporator is used for removing a solvent well below its boiling point, leaving behind the less-volatile material that was dissolved in that solvent.
