  The rotary evaporators described in Patent Documents 1 and 2 both rotate the flask to rotate the object to be stirred in the flask, drop the object to be stirred that has moved upwards by the rotation, and stir repeatedly. Therefore, the substance to be stirred was difficult to disperse in the flask, and stirring and mixing were not always sufficient. In addition, since the solution in the flask is heated with warm water in the constant temperature water tank, it can only be heated to about 90 ° C., and there is a problem that it takes time to vaporize the solution in the flask. . Further, since the container rotates, it is difficult to maintain the inside of the container in a vacuum state.

  The problem to be solved by the present invention is that it is easy to stir the object to be stirred in the container, the inside of the container can be heated up to a temperature (for example, about 200 ° C.) higher than that of a device that warms with warm water, An object of the present invention is to provide a stirring device that can also be used.

  The stirrer of the present invention is a stirrer that stirs two or more objects to be stirred in a container by vibrating the container, and includes a mounting table on which the container can be placed, a drive motor, and rotation of the drive motor The rotating mechanism is equipped with a rotating mechanism that rotates the mounting table in the vertical direction (vertical direction), left-right direction (horizontal direction), and an oblique direction between up, down, left and right by continuously rotating the mounting table in an eccentric position from the rotation axis. Thus, the container placed on the mounting table is vibrated in those directions to stir the object to be stirred in the container. In this case, it is possible to provide a vertical guide and a horizontal guide for smoothly moving the rotating mounting table in the vertical direction (vertical direction) and the horizontal direction (horizontal direction).

  In the agitating device of the present invention, there is provided a forward / backward swing restricting means for restricting the back and forth of the rotating mounting table from swinging back and forth, so that the rotating mounting table can be smoothly moved vertically without swinging back and forth. It can also be made to be able to vibrate horizontally and diagonally. The stirring device can be provided with a fixture for fixing the container placed on the mounting table and stabilizing the container during rotational vibration. The mounting table can be provided with heating means (heating means) capable of heating (heating) the container, and the container can be connected to a vacuum device so that the inside of the container can be evacuated. A cartridge heater or other heating device can be used as a heating source.

The stirring device of the present invention has the following effects.
(1) In the stirring device of the present invention, since the mounting table rotates and vibrates in any of vertical, horizontal, and diagonal directions, the object to be stirred in the container placed on the mounting table is either vertical, horizontal, or diagonal. As a result, the stirring and mixing of the object to be stirred is more reliable than the case where the reciprocating vibration is only performed.
(2) Since the vertical guide and the horizontal guide for guiding the rotating mounting table in the vertical direction (vertical direction) and the horizontal direction (horizontal direction) are provided, the rotation of the mounting table becomes smooth.
(3) Since the forward / backward swing restricting means for restraining the mounting table from swinging back and forth is provided, the rotating mounting table does not rattle back and forth, and can rotate and vibrate smoothly in the vertical, horizontal and diagonal directions. The stirring of the object to be stirred is ensured.
(4) If the container placed on the mounting table is fixed with a fixture, the container placed on the mounting table will not be displaced or dropped during rotational vibration, and damage to the container can be prevented.
(5) Since the container is rotated and oscillated by rotating the mounting table instead of rotating the container, the vacuum device is easily fitted in the container in an airtight manner, and the inside of the container is easily placed in a high vacuum state.
(6) Since the inside of the container can be heated by a heating means (heating means), the temperature in the container can be increased compared to the case of warming with warm water, and when the solvent is put in the container, the solvent is evaporated. The solvent can be easily removed while stirring.
