Product Description

 About electric pump for rotary evaporator:

The electric pump is a device that creats, improves and maintains vacuum enviroment in a closed space. The vacuum enviroment with lower atmospheric pressure can be helpful to some experiments. 


The electric pump has been widely used in evaporation, distillation, crystallization, filtration, depressurization and sublimation etc, by working with rotary evaporator or jacketed glass reactor. 





Features of the electric pump:

- Integrated design: Integrate the pump with motor to make the whole product compact and light
- Anti-backflow design to prevent the oil from flowing back, keep clear inside environment and enhance the stable function of the system.
- Big starting torque special design to guarantee motor starting normally even under low temperature in winter.
- Low noise and vibration Elastomic coupling insert.
- Environment friendly special filter at the exhaust port to avoid oil spraying and spilling, elimating exhaust pollution of oil mist.
