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.

Jul 26, 2016 The bulb in the middle is cooled with liquid nitrogen (I usually immerse it before attaching) and I use a heat gun/hot water bath on the bulb containing the crude product. I also have a little piece of cardboard between the two bulbs to insulate them from each other. So far it’s worked great for a number of compounds on 10mg-5g scale.

Once the flask changes in temperature and becomes cool to the touch, lower the mechanism into the water bath or lift the water bath to the evaporation flask (depending on the rotovap you are using). Make sure that the solvent level is equal to the water bath level. Never put the flask so low that the Keck clip touches the water.
