Mixing device for solution and powder precipitate

A mixing device which rotates a mixing container that is formed long along a vertical direction and has a decreasing circumference at an upper end to mix contents contained therein, the mixing device comprising:

• a guide module which has a preset length, to which the mixing container is rotatably seated along a longitudinal direction and to which the mixing container is selectively fixed to be attachable and detachable;
• a rotating module which is provided on the guide module and selectively rotates the mixing container so that a first rotation axis is formed along the vertical direction of the mixing container;
• and
• a tilting module which is formed long along the vertical direction, has a second rotation axis on both sides along a width direction of the guide module, is rotatably coupled, and selectively rotates the guide module in the vertical direction to tilt the mixing container in a direction intersecting the first rotation axis.
