What Comprises a Complete Rotary Evaporator System?

What Comprises a Complete Rotary Evaporator System?

Apr 18, 2018 The main purpose of a rotary evaporator is to increase the rate of evaporation of a solvent. It does this via three methods: The vacuum decreases the pressure in the system, lowering the boiling temperature of the solvent. The rotation increases the surface area of the solvent. The water bath heats the solvent.

Why Rotary Evaporation Is More Efficient Than Standard

Why Rotary Evaporation Is More Efficient Than Standard

Jul 19, 2018 Water takes a lot of energy to heat, and heating a bath from room temperature (usually 20 - 25C) to, for example, 80C, will take a lot more time than heating it from room temperature to 30C (a common target vapor temperature for rotary evaporation). Oil baths may take even longer to heat, as they can go as high as 180C.
