Introduction to Rotary Evaporator
A rotary evaporator, also known as a rotovap, is a laboratory device used for separating solvents from samples using evaporation. The device consists of a rotating flask and a condenser that is cooled by either air or water. The sample is placed in the flask and heated, causing the solvent to evaporate and then condense in the cooled condenser. This process effectively separates the solvent from the sample, leaving behind a concentrated residue. The rotary evaporator is commonly used in chemistry, biology, and pharmaceutical research, as well as in the food industry for molecular cooking. Its ability to handle small sample sizes and low boiling-point solvents make it a valuable tool for laboratory applications.
