It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

This concrete implementation provides a centrifuging tube, and it is big that the sample exposes the area each other when having solved among the prior art simultaneously to a large amount of multiple type of sample preliminary treatment, easy cross contamination's problem.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

As shown in figure 1, the centrifuge tube comprises a tube body 4 and a ventilation cover 3, the top of the ventilation cover 3 is provided with a ventilation hole 8, and the ventilation cover 3 is detachably arranged at the tube opening of the tube body 4. So set up, can make the mutual exposure area of the sample in each centrifuge tube reduce to sample in the centrifuge tube is difficult for leaking from bleeder vent 8, and external sample is also difficult for getting into the centrifuge tube through bleeder vent 8 on the ventilative lid 3, when having solved a large amount of multiple type of sample and carrying out the preliminary treatment, the easy cross contamination's of sample problem.

In order to better solve the problem of sample cross contamination, the inside of the air permeable cover 3 of the centrifugal tube is provided with a partition plate 2, and the partition plate 2 is provided with a plurality of through holes. So set up, can make the aqueous vapor in the sample spill from the through-hole when carrying out dry preliminary treatment to the sample on the one hand, on the other hand also can prevent that the sample from leaking away from centrifuging tube inside to indirectly prevent the cross contamination of sample. The top surface of the ventilation cover 3 can be also provided with a boss 7, and the ventilation holes 8 penetrate through the boss 7 and the top surface of the ventilation cover 3. So set up, can prevent effectively that sample granule or powder that drops on the top surface of ventilative lid 3 carelessly from 8 landing entering centrifuge tubes of bleeder vent inside, and then avoid the inside sample of centrifuge tube to receive the pollution.

In order to prevent the problem that the sample leaked at the in-process that shifts to make the centrifuging tube possess the function of sealed storage sample, a sealed lid 1 still can be established to the centrifuging tube, and sealed 1 detachable of lid sets up in the top of ventilative lid 3, is provided with between sealed lid 1 and the body 4 and connects rope 9, sets up sealed lid 1 that connects rope 9 and can prevent to hold the centrifuging tube of different samples and uses thoughtlessly, avoids causing the cross contamination of sample.

In the pretreatment operation process, in order to ensure that the sealing cover 1, the breathable cover 3 and the tube body 4 are stably and reliably connected and are convenient to install and disassemble, the sealing cover 1, the breathable cover 3 and the tube body 4 of the centrifugal tube are sequentially connected through threads. So set up, can also prevent that the sample from leaking and causing the waste and the environmental pollution of sample in the joint gap between sealed lid 1, ventilative lid 3 and body 4. For preventing the problem that sealed lid 1 and ventilative lid 3 are not screwed up or are not unscrewed appear in the preliminary treatment in-process, the sealed lid 1 of centrifuging tube and the lateral wall surface of ventilative lid 3 can set up anti-skidding texture to increase the frictional force between hand and sealed lid 1 and ventilative lid 3.
