PROBLEM TO BE SOLVED: To provide a device which increases temperature differences between crystallizing liquid in a tank and a metallic wall of a cooling part which is in contact with a coolant in the same manner as the case of a large scale of crystallization even in the case of a small scale of crystallization and can be split into a tank part, a cap part, a cooling means, a stirring means and a fixing means. SOLUTION: This device is provided with the cylindrical tank part made of glass, the cap part made of glass, the cooling means consisting of a cooling part made of metal which exists near the inner wall of the tank part and enables introducing the coolant, and a supporting part which exists between the tank part and the cap part and supports the cooling part, a stirring means and the means for fixing the cooling means. Therein, a jacket made of glass which enables introducing a medium for temperature adjustment is extended on the side surface of the tank part or a bath for temperature adjustment is extended on the lower part of the tank.
