Rotary evaporator is a common laboratory equipment to remove solvent from a mixture of compounds, the simple configuration of rotavapor is motor, evaporation flask, heating bath (water bath / oil bath), condenser, collection flask, etc.
The simple structure and working principle of rotary evaporator
The evaporation flask is an eggplant or round bottom flask with a standard ground joint , which is connected with the vacuum pump through a highly reflux serpentine condenser,Another opening of the condenser is connected to the collection flask with a grinding mouth for receiving the evaporated organic solvent.
The rotary evaporator can seal and reduce pressure to 400-600 MMHG. The solvent in the evaporation flask is heated with a heating bath. The heating temperature can be close to the boiling point of the solvent, at the same time, rotating the evaporation flask, the rotating speed could keep at 50-160rpm/min, make the solvent being thin film, increase evaporation area. In addition, under the effect of efficient condenser, the hot steam can be rapidly liquefied to speed up the evaporation.
So rotary evaporator is an ideal basic instrument for concentration, drying and recovery. If you want to know more detail of rotary evaporator, welcome contact info@toptionlab.com 24h/7days online service.
