What Are Rotovaps and How Can They be Used? - Maratek

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. A rotovap acts like a filter to separate the unwanted components in the extract as a final step to crude oil. The rotovap is a simple concept with a lot of moving parts.

Rotovap Distillation: What Is A Rotary Evaporator?

Jul 21, 2017 A rotary evaporator or rotovap is an essential tool in a processing facility. Its primary use is in the recovery of ethanol after a winterization or extraction process. Although we’ll be focusing on how a rotovap operates during a basic ethanol recovery, know that it can be applied in the recovery of many other solvents that are compatible with the gasket materials.

Mar 05, 2020 Rotary evaporation requires a rotovap to rotate a flask under a vacuum. This rotation increases the surface area of the solvent, increases the rate of evaporation and reduces any chance of bumping. Since the process takes place in vacuum, it reduces the boiling point of solvent and provides a base for solvent extraction.

May 19, 2009 Luckily, I get to keep the rotovap stuff at work. I have never had any luck with a water aspirator. While it is true that the saturation vapor pressure of water at 18 C is only 21 millibar, and most alcohol work is done above that number, my rotovap is old and doesn’t seal well, and the aspirator doesn’t have the cojones.

Sep 23, 2019 The two main types of pumps used in rotary evaporator setups are diaphragm (membrane) pumps and rotary vane pumps. Diaphragm Pumps Also known as membrane pumps, diaphragm pumps are positive displacement pumps that utilize a series of chambers, diaphragms, and valves. The valves open and close to move air from one chamber to another.
