An embodiment of the present invention relates to a device for controlling the concentration of a solution with a solution cooling device with a remarkably simplified structure capable of preventing inconvenience of work in comparison with an existing device for controlling the concentration of a solution by filling a space configured by including a spring-shaped cooling tube received in an outer cylindrical container with water and passing a nickel specimen solution through the cooling tube. The solution cooling device includes the outer cylindrical container with both closed ends and the spring-shaped cooling tube through which the specimen solution passes. Both ends of the cooling tube are arranged outside the outer container. |
