FAQs
What exactly is a rotary evaporator, and what’s it used for?
Think of a rotary evaporator, often called a “rotovap,” as your lab’s superhero for solvent removal! It’s a device designed to efficiently and gently remove solvents from a sample without harsh heating that could damage your precious compounds. Basically, it combines a rotating flask, a heating bath, a vacuum system, and a condenser to evaporate and recover solvents.
The magic happens by reducing the pressure inside the system. This lowers the boiling point of the solvent, allowing it to evaporate at a much lower temperature than normal. The rotating flask keeps the liquid sample spread thinly, maximizing surface area for even faster evaporation. Then, the solvent vapor travels to the condenser, where it cools and turns back into a liquid, ready to be collected and reused or disposed of properly. Rotovaps are widely used in chemical labs for everything from concentrating solutions and purifying products to drying out solids.
