Introduction about  Evaporation
Evaporation by using a rotary evaporator is the most common used method to separate a solvent. Every student or trainee in chemistry will sooner or later learn how to operate a rotary evaporator. The Rotavapor® R II focuses on the basic requirements of classical laboratory applications in education and research alike
 
The Rotavapor® R 3 focuses on the basic requirements of classical laboratory applications in education and research alike. It covers the essential functions in a convenient and robust manner without compromising quality or safety - an instrument for gentle evaporation in laboratory application
 
The Rotavapor R-220 SE (Second Edition) is a further development of the very successful industry approved Rotavapor R-220. Many proven elements have been carried over from the original R-220. However, a few new features have been introduced in relation to safety and ease of use.
