What will Influence the Working Efficiency of Rotary Evaporator?
For products of the same specification, the major factors include the steam temperature, the vacuum degree and the cooling water temperature. Restricted by bad heat resistance of some materials, the steam temperature cannot be improved unlimitedly during the working. Hence, the high vacuum degree and low cooling water temperature are two main factors to improve the working efficiency. (The cryopump can be selected to lower the temperature.)
How does a Rotary Evaporator Remove Solvent?
A rotary evaporator can remove solvent through the continuous rotation of the evaporation flask. There are several necessary components involved in the process of removing solvent, including a evaporation flask, a water/oil bath, a vacuum pump, a condenser and a receiving flask. Specifically speaking, the stepless speed regulation is adopted to make the evaporation flask rotate at a constant speed. By the rotation, materials can form a large area of uniform thin film on the inner wall of the flask. The evaporation flask is heated evenly by a water or oil bath, and materials, with a lower boiling point, is evaporated rapidly under the vacuum condition. The solvent steam is recycled in the receiving flask after being cooled by the high efficiency glass condenser. The process of removing solvent is completed.
