Feb 14, 2021 Heating Mantle – chemists use heating mantles to drive chemical reactions by converting electricity into heat. Heating mantles are controlled by a variac that regulates the supplied voltage. Some heating mantles have a built-in variac, but in most cases the variac is a separate component. Heating mantles are often placed on top of magnetic ...

Step 3: Distill Citrus Peels. This step is as easy as it sounds. Just turn on your heating mantle, and wait for the water to start boiling. As it boils it will start to create yellow-pale bubbles in the flask. This is the oil that is being separated from the lime peels and evaporated with the water. Eventually, you will be able to see a clear ...
