50 Years of Rotary Evaporation - Bara Scientific

In the year 2007 BUCHI Labortechnik AG celebrates the invention and the 50 year success story of the rotary evaporator. One cannot imagine a modern laboratory without a rotary evaporator as nowadays evaporation and distillation are still the most frequently used separation methods.

What is the purpose of using the rotary evaporator? - Lab .

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Understanding Concentration and Evaporation Technology .

A rotary evaporator is essentially similar, but is for a single sample contained in a flask (see Figure 6). The vortex created generates a large sample surface area for evaporation, making the process relatively fast. However, the resultant dried product is spread across the vessel walls, which can make sample recovery more difficult.

Evaporator - Wikipedia

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.

Rotary Pumps - an overview | ScienceDirect Topics

Rotary pumps use a variety of means to generate flow. A pair of gears with many teeth (external to the gear and called an external gear pump) in gear pumps or a few lobes in lobe pumps is demonstrated in Fig. 23.2.Internal gear pumps use a gear within a gear design; internal means the teeth of one gear are on the inside, projecting inward. Gear pumps are useful for pumping viscous liquids or .
