Rotovap Distillation: What Is A Rotary Evaporator? | BVV

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.

The Solution Was Rotovap

A rotovap (rotary evaporator) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure.

Rotovaps: Are Rotary Evaporators Outdated in Solvent …

As the rotovap evaporates the solvent under vacuum, the solvent can be sucked up in its entirety, leading to the loss of the sample - not to mention the loss of time and money for the company. Due to their inherent technological limitations, evaporating solvents with rotary evaporators can be painfully slow, especially for high boiling point solvents, such as DMF (Dimethylformamide) …

What is the purpose of using the rotary evaporator?

Two key components of the rotovap allow for a gentle, precise, and efficient distillation not found in conventional distilling apparatuses: 1) the solvent is removed under vacuum, which lowers its boiling point, eliminating the need for high-temperature distillation, and 2) the rotation of the evaporating flask, immersed in a heated water bath, increases the surface area of the …

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).
