Preferably, the fixed plate is in regular hexagon.
Preferably, there are four the card slot and fixture block are respectively provided with.
Preferably, first rubber ring and the second rubber ring are symmetrical arranged about pipe lid.
Preferably, the side of the pipe tops is equipped with tag block.
Preferably, the surface of the screwed pipe and threaded cap is provided with anti-slip layer.
Compared with prior art, the utility model has the beneficial effects that：This kind of centrifuge tube tube body and pipe cap pass through a soft folding
Structure connection, soft folded structure can arbitrarily bend, be formed between the first glassy layer and the second glassy layer of vacuum glass material true
Dead level keeps the effect of resist compression of centrifuge tube more preferable, and centrifuge tube is made to be not easy the rupture in high speed centrifugation, not only practical but also safe, in the first rubber
Under the action of cushion rubber and the second rubber ring, threaded cap will not be covered from pipe to fall off, and rotates rotation button, and threaded cap rotation passes through spiral shell
Line lid and screwed pipe cooperate, and fixture block and card slot cooperate so that centrifuge tube is not in collapse plug under high speed centrifugation state
The phenomenon that, it is therefore prevented that sample leaks, and the pollution so as to avoid sample to environment keeps experimental result impacted, label
The setting of block is preferably marked different centrifuge tubes, it is not easy to malfunction, facilitate the progress of experiment.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-4, a kind of embodiment provided by the utility model：A kind of centrifuge tube, including tube body 1, pipe lid 6 and soft
Folded structure 12, the outer layer of tube body 1 are provided with the first glass tube 18, and the internal layer of tube body 1 is provided with the second glass tube 3, the first glass
