[0022] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the content of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments. EMBODIMENT

[0025] Reference Figs. 1-4 For the embodiments of the present application, the embodiments provide a novel detachable complete centrifugal tube, comprising,

[0026] The frame mechanism 100 comprises a large pipe 101, an outer locking thread 102 arranged at the end of the large pipe 101, and a balancing assembly 103 connected through the outer locking thread 102;

[0027] The replacement mechanism 200 comprises a bottom pipe 201, a sleeve thread 202 arranged in the inner cavity of the bottom pipe 201, an auxiliary assembly 203 arranged on the inner wall of the sleeve thread 202, and a connecting assembly 204 arranged in the inner cavity of the balancing assembly 103 and matched with the balancing assembly 103;

[0028] The balancing assembly 103 comprises a cover 103a movably mounted on the surface of the outer locking thread 102, an inlet 103b communicated on the side wall of the cover 103a, and a closing cover 103c movably connected on the inner wall of the inlet 103b. The balancing assembly 103 further comprises a connecting block 103d fixedly mounted on the side wall of the closing cover 103c, a traction rope 103e fixedly mounted on the side wall of the connecting block 103d, an empty chamber 103f arranged in the inner cavity of the cover 103a, and an inner locking thread 103g arranged on the inner wall of the cover 103a.

[0029] Specifically, the large tube 101 is not much different from a common 50 mL centrifuge tube. The volume of the cavity in the cover 103a is 1-2 mL. Water can be added when the sample volumes are not much different, so that the original sample volume can be conveniently balanced without changing the solid-liquid volume, which is crucial for accurate solid-liquid extraction process and directly affects the accuracy of the subsequent yield and determination.

[0030] The auxiliary assembly 203 comprises a sleeve 203a movably connected on the inner wall of the sleeve thread 202, a bottom thread 203b opened on the side wall of the sleeve 203a, and a sealing thread 203c arranged on the surface of the sleeve 203a.

[0031] Further, the volume of the bottom tube 201 and the sleeve 203a is about 20 mL, which is connected together by the sleeve thread 202 and the bottom thread 203b. The balancing assembly 103 can be used for balancing. If the sample volumes in the bottom tube 201 and the sleeve 203a are not much different, the samples can be loaded respectively, so that the centrifuged sample is multiplied, and the centrifugal efficiency is improved.

[0032] The connecting assembly 204 comprises a three-way tube 204a movably connected on the surface of the inner locking thread 103g, and an inner thread 204b arranged on the inner wall of the three-way tube 204a. The connecting assembly 204 further comprises an outer thread 204c arranged on the outer surface of the three-way tube 204a, and a connecting thread 204d opened on the bottom of the three-way tube 204a.

[0033] Preferably, three three-way tubes 204a are provided, which are sequentially connected end to end by the outer thread 204c and the inner thread 204b, and can be freely combined. Any one of the three-way tubes 204a can be used as a balancing part, or all of them can be used for loading samples. The centrifugal efficiency can be improved by three times.

[0034] It should be noted that the outer locking thread 102 is movably connected with the inner locking thread 103g, the sleeve thread 202 is movably connected with the bottom thread 203b, and the sealing thread 203c is movably connected with the inner locking thread 103g.

[0035] In use, after the inner locking thread 103g of the balancing assembly 103 is connected with the outer locking thread 102 on the large tube 101, water is added in the cavity in the cover shell 103a to complete balancing, and centrifugal operation can be performed. When the sample amount is small, the large tube 101 is replaced by the bottom tube 201 and the sleeve tube 203a, different samples are added in the bottom tube 201 and the sleeve tube 203a respectively, the sleeve joint thread 202 of the bottom tube 201 is connected with the bottom thread 203b of the sleeve tube 203a, and the sealing thread 203c of the sleeve tube 203a is connected with the balancing assembly 103, so that the centrifugal operation of two different samples can be quickly completed. When centrifugation of multiple samples is required at the same time, samples can be added in the three-way tube 204a respectively, the three-way tube 204a can be freely combined as a balancing or sample part, or all can be used to place samples, and the centrifugal efficiency is improved by three times.

[0036] In summary, by connecting the inner locking thread 103g of the balancing assembly 103 with the outer locking thread 102 on the large tube 101 and adding water in the cavity in the cover shell 103a to complete balancing, simple and stable centrifugal operation is realized. When the sample amount is small, the large tube 101 is replaced by the bottom tube 201 and the sleeve tube 203a, different samples are added in the two tubes respectively, and the sleeve joint thread 202 and the sealing thread 203c are connected, so that the centrifugal operation of two different samples can be quickly completed, greatly improving the flexibility and efficiency of the experiment. When centrifugation of multiple samples is required at the same time, samples are added in the three-way tube 204a and freely combined, which can be used as a balancing part or all for placing samples, so that the centrifugal efficiency is improved by three times, significantly enhancing the diversity and efficiency of experimental operation, and bringing great convenience and efficiency improvement to laboratory work.
