Laboratory 1L/5L/10L/20L/50L Rotary Evaporator for Solvent Evaporation

Product Description

A Lab Vacuum Evaporation Machine Rotary Evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure. However, careful application also allows for the removal of a solvent from a sample containing a liquid compound, if there is minimal co-evaporation (azeotropic behavior) and a sufficient difference in boiling points at the chosen temperature and reduced pressure.


The Zhengzhou Greatwall 0.5L-2L Lab Vacuum Evaporation Machine Rotary Evaporator come with a modular heating bath and digital temperature/rotation control. Its optimized bath volume allows for rapid heat-up times. The condenser unit has specially designed glass tubes that utilize surface area extremely efficiently. Another important aspect of the 0.5L-2L rotary evaporators is the safety features, which includes dry-run protection, water bath over-temperature shut-off protection, and fuse protection.

The Zhengzhou Greatwall 0.5L-2L Lab Vacuum Evaporation Machine Rotary Evaporator features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 180 rpm. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum, effectively reducing the boiling point of the solvents and removing the vapor phase, making the process much more efficient. Each unit is also equipped with an easy-to-use vacuum release and a continuous feed system, which allows solvent to be constantly drawn into the rotating flask without needing to stop the operation.

The Zhengzhou Greatwall 0.5L-2L Lab Vacuum Evaporation Machine Rotary Evaporator Digital water bath operates from ambient temperature to 99°C with PID temperature control stepping at 0.1°C increments. Heating coils are located directly inside the pan for the most efficient heating possible. A built-in overheat protector will shut down power, should the controller fail.

The Zhengzhou Greatwall 0.5L-2L Lab Vacuum Evaporation Machine Rotary Evaporator Standard Glassware Set 0.5L,1L or 2 liters pear shaped evaporating flask, 1 liter round-bottomed receiving flask, and vertical/oblique condenser.


The Zhengzhou Greatwall 0.5L-2L Lab Vacuum Evaporation Machine Rotary Evaporator Features:

  • Solvent-resistant PTFE and Viton gaskets ensuring long time operation.
  • Specialized motor with extremely compact, intermeshed worm and worm gear provides precise driving for very quiet, vibration-free operation.
  • Downward-condensing vacuum connection design ensures safe vacuum operation.
  • Modular design (individual rotary and water bath modules) for easy future upgrades.
  • Easy multi-level manual lift with secure lock for the evaporating flask.
  • Easy, straight-forward visual operation with digital speed and temperature display.
  • PID temperature controller ensures accurate temperature control is maintained.
