Rotary Evaporator - Sampling & Analisis

The rotary evaporator is a piece of equipment that is designed to allow you to distill a liquid under conditions of reduced pressure. Since the pressure within the system is reduced, it means that the liquid can be distilled at a lower temperature than it would at atmospheric pressure. This is a very safe and fast method of distilling flammable

How to use a Rotary Evaporator - University of California

Apr 01, 2010· 4. The dial on the motor is used for speed control of the flask rotation. A typical rotavap uses a variable speed sparkless induction motor that spins at 0-220 rpm and provides high constant torque. A good setting here is 7-8. 5. The aspirator vacuum is turned on.
