Description of the Related Art Since micro tubes for testing are not strictly standard products, there is a variation in the product dimensions, especially the outer diameter, of each manufacturer. A plurality of slightly larger insertion holes are provided, and the microtube is inserted therefrom to merely suspend and hold the microtube.
When this is used for horizontal (eccentric vibration) agitation, not only can the microtube be tilted or rotated, so that all the microtubes cannot be agitated uniformly, but also the collision noise due to rattling causes considerable noise. Had been raised. In addition, there is a problem that the microtube comes out of the frame-shaped casing due to centrifugal force or buoyancy when the microtube is turned upside down to repeat the vertical rotation of the microtube or when immersed in a constant temperature water bath for heating. As a means for solving these problems, a rubber plate R provided with a slightly smaller insertion hole is attached to the upper surface plate of the frame-shaped housing as shown in FIG. 3A, or FIG. As shown in (1), there is a proposal to attach a suppressing cover C for preventing the microtube from coming off on the upper plate.

率が低下するという課題があった。However, when the rubber plate R is repeatedly inserted and withdrawn from the microtube, the rubber plate R is easily peeled off from the upper plate due to the stress, or the rubber plate R is partially peeled, resulting in a wavy state. Since the inserted microtubes are inclined, the microtubes cannot be held in a normal alignment state, and when attaching the retaining cover C for preventing the detachment, it is necessary to attach / detach the retaining cover C before and after the work. There is a problem that the operation is complicated and the work efficiency is reduced.

When the tapered intermediate portion of the conical peripheral surface 1a at the lower portion of the microtube 1 reaches the edge 7 of the dish-shaped stop hole 8 and stops, the microtube 1 is further lightly pushed from above. It is. Then, the microtube 1 rides over the edge 7 with its flexibility and the conical taper so that the thick outer peripheral portion of the conical portion slightly narrows.
The microtube 1 is fixed in such a manner that it slightly bites into the large-diameter portion of the tapered intermediate portion of the lower conical peripheral surface 1a to prevent the microtube 1 from floating.

ずかなものなのである。When this is subjected to horizontal stirring, as shown in FIG. 1, a required number of microtubes 1 are inserted and fixed, and then the frame-shaped casing 5 is placed and fixed on a stirring table 10 of a stirrer 9. After the stirring, the frame-shaped casing 5 is removed from the stirring table 10 after the stirring, and the microtube 1 is taken out. When taking out the microtube 1, the microtube 1 can be easily pulled out simply by pulling up the microtube 1 against the biting force of the edge 7. That is, the biting force due to biting of the edge 7 is sufficient to hold and fix the lightweight microtube 1 during stirring, but the force required by an operator when inserting and removing the microtube 1 is small. It's a little thing.

The tube 1 is set in the frame-shaped housing 5. By the bite fixing by the edge 7 biting, the microtube 1 is surely prevented from coming off due to centrifugal force or buoyancy.

ることができるという効果を生ずる。[Effects of the Invention] In the present invention, as described above, in a frame-shaped housing having a large number of test microtube insertion holes on the upper surface plate, the insole plate is horizontally positioned below the middle of the frame-shaped housing. At the bottom of the insole plate below the insertion hole opening, a dish-shaped stop hole is provided at the position below the insertion hole opening, with a slope of upper and lower sides and a lower end peripheral surface serving as an edge for biting. By slightly pushing down the inserted microtube from the position where the lower conical peripheral surface reaches the edge and stops, the thick outer peripheral portion of the lower conical peripheral surface surpasses the edge by the flexibility and taper of the material. Since the microtube is bitten and fixed by biting the edge, the upper surface of the microtube is held down by a holding cover that requires time for attachment and detachment, and a rubber plate that may peel Micro in part To make cuttings and without requiring tightening the cube produce an effect that it is possible to extremely easily reliably fixed microtube.

できるという効果を生ずる。[0012] Since the lower conical peripheral surface of the inserted microtube comes into contact with the edge and once pressed down, it is slightly pushed down, so that even microtubes of various manufacturers having irregularities in the outer diameter are used. An effect is obtained in that it can be securely inserted and fixed in the same manner. Moreover, because of the stable fixing method of preventing bite by biting the edges, it is possible to prevent rattling, tilting, rotation, etc. of the micro tube during horizontal stirring, to perform uniform stirring, and to prevent generation of noise. The effect of preventing the microtube from coming off due to centrifugal force or buoyancy even when the mixer is turned over or immersed in a thermostatic water bath is produced. In addition, since parts that easily deteriorate are not used, there is an effect that maintenance-free operation can be performed for a long period of time.
