How Rotary Evaporator Heat - Jurnal prinsip rotary evaporator pdf. 2011). The rotating evaporator serves to separate a solution from its solvent so that the extract is produced with certain chemical content as desired (NuGroho and Dadang, 1999). The rotary evaporator is a tool used to extract, efficient and soft solvent evaporation.
A rotary evaporator is a specially designed instrument for the evapora- tion of solvent (single-stage or straight distillation) under vacuum. The evaporator consists of a heating bath with a rotating flask, in which the liquid is distributed as a thin film over the hot wall surfaces and can evaporate easily.
