In this exercise, you can practice setting up a rotary evaporator, using it to remove solvent and then correctly shutting it down to remove your sample. You will need to make sure that the vacuum is correctly established, that the flask is rotating at an appropriate speed, and that the flask is gently heated using the water bath. When shutting down, ensure that you perform these tasks in the correct order. By working through the exercise, you will become familiar with the equipment and how it should be used. This is your opportunity to explore different options and to understand the consequences of your choices. At any stage, you can get specific feedback about one element that requires attention and an indication of how many others need changing
