Rotary Evaporator 0.5-2L
Rotary Evaporator 0.5-2L
RE-52A rotary evaporator is developed by applying the principle of constant temperature heating and thin film evaporation under vacuum and negative pressure. The instrument is controlled by imported high-grade frequency converter. Stepless speed regulation makes the glass rotary bottle rotate at constant speed. Material forms a large area of uniform film on the wall of the bottle. Then the rotating bottle is heated uniformly by a controllable constant temperature water bath pot. Under the condition of vacuum extraction, the solvent vapor is evaporated at high speed. The solvent vapor is cooled by a high-efficiency glass double condenser and recycled into the collection bottle. The instrument is also equipped with feeding interface and feeding mechanism to facilitate automatic and continuous operation in the evaporation process.

The main components of a rotary evaporator are:
- A motor unit that rotates the evaporation flask or vial containing the user’s sample.
- A vapor duct that is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample.
- A vacuum system, to substantially reduce the pressure within the evaporator system.
- A heated fluid bath (generally water) to heat the sample.
- A condenser with either a coil passing coolant, or a “cold finger” into which coolant mixtures such as dry ice and acetone are placed.
- A condensate-collecting flask at the bottom of the condenser, to catch the distilling solvent after it re-condenses.
- A mechanical or motorized mechanism to quickly lift the evaporation flask from the heating bath.
The vacuum system used with rotary evaporators can be as simple as a water aspirator with a trap immersed in a cold bath (for non-toxic solvents), or as complex as a regulated mechanical vacuum pump with refrigerated trap. Glassware used in the vapor stream and condenser can be simple or complex, depending upon the goals of the evaporation, and any propensities the dissolved compounds might give to the mixture (e.g., to foam or “bump”). Commercial instruments are available that include the basic features, and various traps are manufactured to insert between the evaporation flask and the vapor duct. Modern equipment often adds features such as digital control of vacuum, digital display of temperature and rotational speed, and vapor temperature sensing.
