Aug 21, 2019 A 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.

Efficient evaporation performance, quick set up, and simple and easy flask handling all contribute to the reduction of time spent on the evaporation process, from start to end. Features that facilitate time saving: Easy transportation of flasks via flask handling carts; Guided flask installation; Large surface area for evaporation

Evaporation efficiency. A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires 0.09 kg of steam. Without the thermocompressor, the specific steam consumption would be approx. 0.55 and 0.2 kg per kg of water evaporation respectively.

Feb 25, 2021 Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.

May 30, 2019 Why use a Rotary Evaporator? A rotary evaporator is often utilized because it is the fastest and most efficient method to remove low boiling organic chemicals from a mixture of compounds. The rotovap works by employing three simple methods. The first is to increase the rate of evaporation of the solvent by reducing the pressure to lower the ...

Nov 04, 2021 The rotary evaporator is more efficient than simple or conventional distillation equipment. This is due to the presence of a vacuum system coupled to its structure, and that when the sample is rotated a greater contact surface is generated, which allows evaporation to occur more quickly, and it also has a heating system. which makes the ...

Rotary evaporators are used in distillation for efficient and gentle removal of solvents from samples through evaporation. This method is normally applied to low boiling solvents such as n-hexane and ethyl acetate from compounds that would normally be solid at room temperature and normal atmospheric pressure.
