A fractionating and refining device includes a solution sending flow path for supplying a solution including a fractionated target component from a tip end thereof, a gas supply flow path for supplying gas from a tip end thereof, a collecting vessel, and a warming mechanism for warming the collecting vessel to such a temperature as to facilitate evaporation of a solvent in the solution in the vessel. The collecting vessel includes a vessel main body having a bottom and a lid which closes an opening portion of the vessel main body and which can be opened and closed. The lid includes a solution inlet to which the tip end portion of the solution sending flow path is connected and through which the solution from the solution sending flow path is supplied into the vessel main body, gas inlets to which the tip end portion of the gas supply flow path is connected and through which the gas from the gas supply flow path is supplied into the vessel main body, and gas discharge ports connecting an inside and an outside of the vessel main body. |
