RE-2002 rotary evaporator is a specially designed instrument for the evaporation 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. The evaporation rate is regulated by the heating bath temperature, the size of flask, the pressure of distillation and the speed of rotation. Advantages of the rotary evaporator(compared with static apparatus):With a vacuum rotary evaporator you can carry out single-stage distillation runs quickly and gently.

The evaporation capacity of a rotary evaporator is greater than that of a conventional, static distillation apparatus. Heat transmission in the heating bath as well as inside the flask is greatly improved by rotation of the evaporating flask. Rotation greatly enlarges the active surface inside the flask,hastening the evaporation. With the liquid remaining at any one point of the flask wall for a short time only, it is subject to minimum stress during the distillation (no overheating, no incrustation). Bumping and foaming are greatly reduced by the rotation.

RE-2002 rotary evaporators are used for:

1.Distillation of solvent.

2.Concentration of solutions and suspensions.
