What recommended temperature of rotary evaporator?

Rotary evaporator is a very common laboratory equipment for concentration, purification, separation, crystallization, solvent removal, alcohol recovery, etc. Compared with other evaporators ( wiped film evaporator, falling film evaporator, rising film evaporator), its price is cheaper and capacity range is wide (1L-100L), so rotary evaporator is widely and popular used in the pharmaceutical industry, chemical industry, food industry, cosmetics industry, laboratories, research institutes,etc.
For 3L 5L rotary evaporation apparatus , the max setting temperature is 210℃ and actual working temperature could reach 200℃, because we need to take into account the heat loss, it is practically impossible to have no heat loss. Secondly, the quality of the silicone oil (heating source of heating bath) will also affect the temperature that can be reached.
For 10L 20L 30L 50L 100L rotary evaporation apparatus , the max setting temperature is 200℃, the actual working temperature can reach 180℃.
What we are talking about here is the temperature that rotary evaporator can reach. In the process of actual use, the rotary evaporator working temperature will not be used so high, because the heating temperature cannot exceed the boiling point of the solvent, and we generally match the vacuum pump. Under pressure, the boiling point of the solvent will be lower, which will also improve work efficiency. The second is to consider the condensing capacity of the condenser, the evaporation rate cannot exceed the condensation rate, otherwise the condenser may be overloaded. Therefore, the rotary evaporator working temperature is set according to the actual experimental requirements, including the boiling point of the material and the condensation speed of the condenser, etc.
