  • EASY LIFTING MECHANISM: RE-501 rotary evaporators are easily raised or lowered by just turning the handwheel on the oil/water bath drives the bath to lift and go down. Rotary Evaporators are water tank lifting. Its hydraulic pressure assists to push and make the machine lift quickly, drop at a steady speed.

  • VERTICAL CONDENSATION SYSTEM: The condenser adopts two structures. One is the dual pipeline convection principle and is used for evaporating organic solvents. The other is single pipe container with interlayer that could hold cooling water, ice and drikold. Its vertical type decreases volume and is used for evaporating organic solvents. Also, prevents liquid from stagnating
  • PTFE VACUUM SEALING: The fluoro-rubber vacuum seal PTFE evaporating pipe with its multistage configuration is designed to maintain the stability and reduces the boiling point of the solvents. Also, removes the vapour phase by making the process much more efficient which overall brings a good performance. good sealing and heat-resisting.

  • AUTOMATIC TEMPERATURE CONTROL DIGITAL DISPLAY: The digital temperature indicator is mainly designed for easy setting and reading. It is control by pt100 sensor. When the pre-selected temperature is reached the temperature you setted, the controller automatically will turn off the heater supply, When it is lower than the pre-selected temperature, controller will switch on automatically to realize constant temperature. Together with the digital setting and display, the rotary evaporator maintains a stable rotation by using the feedback control feature. By this experimental conditions and steps during a reaction can be saved and repeated in future.

  • ROTATING FLASK AND COLLECTION FLASK: The flasks are made of GG-17 high borosilicate glass which is blowed by hand. Their intensity, concentricity, glossiness, and surface finish are better than rough flasks. As the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface.

  • WORRY FREE WARRANTY: This Rotary Evaporator has a one year manufacturer warranty guaranteed.


The Vacuum Pharmaceutical RE-501 rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts. It 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.

RE-501 rotary evaporator, is also known as rotavap or rotovap. It is especially used for the concentration of extract liquor and distillation of receive liquid when chromatograph. It is heated at a constant temperature, under vacuum conditions to form a film of rotation, high evaporation, and then cooled recovered solvent, especially for heat-sensitive materials crystallization, separation, solvent recovery and other operations.
