50L Rotary Evaporator for Chemical and Pharmaceutical Use
What is a Rotary Evaporator?
A rotary evaporator, also known as a rotovap, is a laboratory instrument used for gentle and efficient evaporation of solvents by lowering their boiling points. It consists of a heating bath, rotating flask, condenser, and a collection flask. This equipment enables the recovery of valuable substances, separates solvents, and aids in sample preparation by removing unwanted components.
How does a Rotary Evaporator work?
At its core, a rotary evaporator operates on the principle of reduced pressure and continuous rotation. The sample flask containing the liquid mixture is placed in a heated water bath. As the flask rotates, the liquid spreads as a thin film across its inner surface. The evaporative process is accelerated by the reduced pressure created in the system using a vacuum pump. The solvent evaporates at a lower temperature, leaving behind the desired compounds.
