Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of homogenization processing equipment, in particular to a centrifuge tube cover with homogenization function and a centrifuge tube. BACKGROUND

[0002] Before detecting an object, a homogenizer is needed to homogenize a detection sample, and then centrifugal separation is performed. The detection sample includes but is not limited to vegetables, fruits, Chinese herbal medicines, aquatic products and meat products. During homogenization processing, an extraction reagent needs to be added. In the prior art, whether it is a handheld homogenizer, a multi-channel homogenizer or a fully automatic homogenizer, they are all open homogenizers, and the extraction reagent is a volatile toxic reagent, which is very harmful to the environment and experimental personnel. Moreover, after homogenization is completed, the sample in the homogenization bottle needs to be transferred to a centrifuge tube for the next step of centrifugal separation, which reduces the work efficiency. Therefore, there is an urgent need for a new scheme to solve the above problems. SUMMARY

[0003] The present application aims to provide a centrifuge tube cover with homogenization function and a centrifuge tube to solve the problems existing in the prior art. The problems of toxic and harmful reagents harming experimental personnel due to the open homogenization bottle during homogenization and the cumbersome process of transferring the sample in the homogenization bottle to a centrifuge tube for centrifugal separation are solved.

[0004] To achieve the above-mentioned purpose, the present application provides the following scheme:

[0005] The present application provides a centrifuge tube cover with homogenization function, which comprises a cover body and a homogenization assembly. The cover body is used to cover the opening of a centrifuge tube. The homogenization assembly is used to homogenize a detection sample and an extraction reagent in the centrifuge tube.

[0006] Preferably, the cover body is detachably connected to the centrifuge tube.

[0007] Preferably, the homogenization assembly comprises a stator, a rotor and a rotor driving device. The stator and the rotor are both arranged on the inner side of the cover body. The stator is fixedly arranged. The rotor is rotatable. The rotor driving device can drive the rotor to rotate relative to the stator and utilize the cutting force and the friction force between the rotor and the object to homogenize the detection sample.

[0008] Preferably, the homogenization assembly comprises a crushing blade and a blade driving device. The crushing blade is arranged on the inner side of the cover body. The blade driving device can drive the crushing blade to rotate.

[0009] Preferably, in use, the centrifuge tube is inverted.

[0010] Preferably, the centrifuge tube cover is made of PE or PP, the stator is made of PE or stainless steel, and the rotor is made of PC or stainless steel.

[0011] Preferably, a plurality of stators are arranged around the rotor.

[0012] Preferably, the stator is provided with friction teeth on the side facing the rotor.

[0013] Preferably, the rotating shaft of the rotor is supported by a fixed bearing, a dynamic sealing ring is arranged below the rotor to seal the gap below the rotor, and a water-absorbing sponge is further sleeved on the rotating shaft to absorb leaked liquid.

[0014] The application also provides a centrifuge tube with homogenization function, which comprises a centrifuge tube and a centrifuge tube cover with homogenization function as described above.

[0015] The application has the following technical effects compared with the prior art:

[0016] In the experimental analysis process, more and more homogenization treatment is needed, but in the above experimental process, the customer uses a handheld homogenizer or a full-automatic homogenizer, and the homogenization bottle is completely open. Figure 1 As shown in the figure, toxic and harmful gases will be volatilized during homogenization, which is very harmful to the experimenters. Even if the homogenizer is placed in a fume hood, there is still a risk of gas volatilization, and it will occupy the limited space of the fume hood. After homogenization, the sample in the homogenization bottle needs to be completely transferred to a centrifuge tube for centrifugal separation treatment. The steps are complicated and inefficient.

[0017] The scheme provided by the application realizes homogenization treatment of the detection sample and the extraction reagent directly in the centrifuge tube by using the homogenization assembly in the centrifuge tube cover with homogenization function, and solves the problem of toxic and harmful reagents invading experimenters due to the open homogenization bottle. After homogenization treatment, the cover is removed, and the centrifuge tube can be directly placed in a centrifuge for centrifugal separation. The experimental process is greatly optimized, and the experimental efficiency is improved. BRIEF DESCRIPTION OF DRAWINGS
