A rotary evaporator consists of a heating bath, a steam pipe with standard ground joint, to the lower end of which the evaporation flask is attached, a condenser with a vacuum attachment and a receiving flask. The rotatable steam pipe is led through a shaft seal into the cooler at its upper end and can be set in rotation using a continuously adjustable motor.
A rotary evaporator, or rotavap, is a piece of equipment that efficiently and gently removes volatile solvents from your product through evaporation. The main components of a rotavap are: An evaporation flask, which contains the sample material. A motor that rotates the flask. A vacuum-sealed vapor pathway, which draws vapor off the sample.
Buchi 20/40/60 rule for Rotary Evaporators Optimal Distillation parameters for a rotary evaporator vary according to solvent in use: 1. Set water bath temperature to 60oC – It does not need to be higher! 2. The cooling water temperature should be below 20oC. 3. Adjust the needed vacuum for a solvent boiling point of 40oC according to list below.

described in Equation (2). The Wx was obtained by weighing the ﬁlms taken out from xylene after wiping off the excess xylene on the surface. About 5 L of the resultant xylene immersion solution was directly injected into the GPC instrument for analysis. The xylene in the final immersion solution was removed using a rotary evaporator at 60 C ...
evaporation flask turns round when you turn on the power switch. Move the lift up or down after you stop rotation of the evaporation flask. If the lift is moved up or down while the evaporation flask is rotating, scalding may occur due to dispersing of hot water. Be sure to move the lift after turning the control knob to the minimum.

May 08, 2020 In general, your bath temperature should be 20C higher than the boiling point of the substance you want to evaporate. And your coolant should be 20C or more lower than the vapor temperature. For example, if the boiling point of your substance is 40C, a bath temperature of 60C and coolant temperature of 20C should provide an optimal setup.
