The Rotary Evaporator

The Rotary Evaporator

a. Add ice and water to the water-circulating pump start circulation through the condenser. (Make sure the water level does not reach the pump-it is not a submersible pump!) Start the aspirator and close the stopcock. Securely clip the partially-filled round bottom flask on the ground glass joint of the splash protector. b. Rotate the flask slowly.

What are Rotary Evaporators and How Do They Work?

What are Rotary Evaporators and How Do They Work?

Feb 25, 2021 What is Rotary Evaporation? Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.

Jun 22, 2020 Continuous rotary evaporation without breaking vacuum: It can be done! Basically, you need 1) a tube that goes from the airvent (?) near the stopcock to your Erlenmeyer full of solution to be rotovapped, 2) an internal tube from the stopcock that reaches down past the condenser tubing, through the rotating shaft and into your bump trap and 3) an appropriate …

A guide to the rotary evaporator - CLASS

Nov 11, 2021 The evaporation flask is rotated in a water bath, which warms the liquid mixture and allows it to boil at lower temperatures (around 40C) due to the reduced pressure. The steam then passes through a chilled coil, converting back to the liquid state, which is collected in another flask. Whiley enjoys using the rotovap to redistil spirits.
