Rotary evaporator capable of continuously distilling

The utility model discloses a rotary evaporator capable of continuously distilling, which relates to the technical field of experimental instruments and comprises a bottom plate. A constant-temperature oil bath pan is arranged on the bottom plate, and a stabilizing device is arranged at the top of the constant-temperature oil bath pan; and two sets of condensation systems are arranged on the bottom plate. According to the utility model, the three-way valve with the feed valve and the condensation system are added on the basis of the original rotary evaporator system, the two condensation systems are connected in parallel, and the three-way valve is used for switching the use of the condensation systems to complete the operation of continuous distillation and condensation, so that when liquid needs to be discharged, the whole system does not need to be stopped to discharge liquid; the three-way valve is rotated to switch the other set of condensation system to continuously condense and collect the condensate,
