Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a test tube mixer equipped with a sample holder for enabling unattended sample stirring by a mixer.

[0002]

[Prior art]

 A test tube mixer is a general-purpose physics and chemistry device used to stir liquids, emulsions, etc. in sample tubes such as test tubes and small flasks.The container is rotated by pressing the container directly against the drive unit and holding it. , Has a structure to stir the contents. However, during agitation, it was necessary for the operator to press and hold the container against the mixer drive section, which made it impossible to operate unattended, which was a problem when agitation for a long time was required.

[0003]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a test tube mixer that can hold and easily remove the container regardless of the stirring speed and the shape of the container when the sample is stirred by the test tube mixer.

[0004]

[Means for Solving the Problems]

 The present invention relates to a test tube mixer in which a sample container supporting pedestal part precesses, and a holding part for covering and holding the head of the sample container placed on the pedestal part is provided, and the holding part is provided via an arm. The test tube mixer is characterized in that it is mounted on an independent stand so that it can move up and down. The shape of the holding part can be a curved surface with a diameter larger than the diameter of the container head. Further, as the material of the holding portion, a material having elasticity and adhesion such as rubber and urethane, or a material having rigidity and adhesion such as metal and plastic can be used.

[0005]

[Advantageous Effects] According to the present invention, since the holding portion that covers and holds the head of the sample container placed on the pedestal is provided, it is possible to stably hold the container during stirring regardless of the shape of the container. Therefore, the stirring and mixing operations for a long time can be performed unattended. In addition, white wax caused by vibration of the mixer can be prevented by holding for a long time.

Further, by connecting the holding portion to the self-standing stand via the arm so that the holder can be moved up and down easily, the restriction due to the height of the container is removed, and the container can be easily attached and detached.

[0007]

【Example】

 An embodiment of the test tube mixer according to the present invention is shown in FIGS. 1, 2 and 3. The sample holder 1 in FIG. 1 has a curved concave surface whose radius is equal to the diameter of the test tube 4 inside the holding surface, and holds the head of the test tube, and the bottom is the base of the test tube mixer 6. It is fixed by touching it. The sample holder 1 is connected to an independent stand 2 via an arm 3 that can be driven up and down, and by adjusting the screws 8 and 9, the position can be easily adjusted according to the height of the container. In addition, 7 is a fixed part for making the stand 2 independent.

FIG. 2 shows an example in which the sample holder 1 molded of urethane rubber is made to be elastic in the vertical direction by the spring 10 and connected to the stand 2 via the arm 3, and the arm 3 is lifted up. Thus, the container 4 can be easily scissored and held between the sample holder 1 and the pedestal 5 of the test tube mixer 6. It can be removed by the same operation. Although the spring 10 is used in this case, this is not always necessary. Further, in this case, a recess is provided on the pedestal portion 5 to facilitate holding of the test tube 4.

FIG. 3 shows an example in which the flask 4 is held on a pedestal portion 5 instead of the test tube 4 shown in FIG. Although these have a configuration different from that of the test tube mixer, it is also possible to directly attach the above stand to the main body of the test tube mixer and integrate them.

[0010]

[Effect of device]

 According to the present invention, when a mixer is used for stirring a sample, it is not necessary for an operator to directly hold it by hand, unmanned stirring and mixing can be performed for a long time, and a container can be easily attached and detached.
