Zhengzhou Keda Machinery and Instrument Equipment Co., Ltd. is specialized in R & D, production, sales, teaching and chemical biology pharmacy equipment integrated company.Company tenet: keeping reputation, valuing contracts, supplying lower prices and better quality equipments to serve the cause of China's scientific research.

Our main products are Circulating Water Vacuum Pump, Low Temperature Reaction Bath, Low Temperature Cooling Fluid Circulating Pump, Rotary Evaporator, Glass Reactor, Magnetic Stirrer, High-pressure Reactor, Water Bath, Drying Oven, Ultrasonic Cleaning Machine, Lift Platform, etc.

Our company keeps credit, and emphasis on contract. We will provide excellent performance products and perfect after-sale service wholeheartedly for the pharmaceutical industry, chemical industry, food, as well as the colleges and universities laboratory service and so on.

Function introduction:

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.

The rotary evaporator is the essence of domestic and foreign similar products, and sets our company successful practical experience. We have developed 10 liters, 20 liters, 50 liters large capacity rotary evaporator. And the equipment’s design follows efficient, practical, economic principles to meet customer's requirements maximally.
