Fractional distillation unit rotary evaporator is heated by water bath(oil bath) to form thin film under the negative pressure condition, evaporate, then condense and recycle the solvent simultaneously. The apparatus are particularly suitable for the heat-sensitivity material’s condensation, crystallization, separation, recovery and so on. It is an important instrument for scientifical research, pilot and production in biological pharmacy, chemical engineering and food industries etc.
