The rotary evaporator is heated by water bath(oil bath) to form thin film under the negative pressure condition, evaporate highly, 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. And reflux extraction can be avaliable for parts evaporator models.
It is one of the necessary basic instruments in the chemical industry, pharmaceutical industry, universities and research laboratories and other units etc., while it is also the main means for producing concentrated extracts and analysis experiments.
