Rotary Evaporator - Built For Visionaries

Rotary Evaporator - Built For Visionaries

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

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.

How do I evaporate water and ethanol using a rotary evaporator?

I am trying to evaporate a number of ethanol and water solutions, which also contain milk protein. However, I am finding the rotary evaporator very slow at doing this; ~4 hours to evaporate 500ml of the solution. Does anyone have any suggestions about how I could optimise the rotary evaporator? Currently, I have the water bath temperature at 65'C and the pressure at around …

Mar 05, 2020 To separate the two, use a rotary evaporator. When connected to a vacuum pump, the rotary evaporator uses the vacuum to lower the boiling point of ethanol, resulting in a quicker evaporation. The resulting extract or oil will be completely free of ethanol. This process also allows ethanol to be recovered for additional extractions.
