Pyöriväkuivaaja
Pyöriväkuivaaja, also known as a rotary evaporator, is a laboratory device used to separate a solvent from a solution by evaporation. It consists of a rotating flask, a heating bath, a condenser, and a vacuum system. The solution is placed in the rotating flask, which is then heated. The solvent evaporates and is carried by a stream of nitrogen or air into the condenser, where it condenses and is collected. The non-volatile components remain in the flask. Rotary evaporators are widely used in chemical, pharmaceutical, and biological laboratories for purifying and concentrating solutions. They offer several advantages, including the ability to handle large volumes of solvent, the use of reduced pressure to lower the boiling point of the solvent, and the ability to recover solvents for reuse. However, they also have some limitations, such as the need for careful operation to prevent contamination and the potential for solvent loss due to splashing. Proper maintenance and calibration are essential to ensure accurate and reliable results.
