Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] Such as figure 1 , 2 As shown, a centrifuge tube includes a tube cover 1 and a tube body 2, the tube cover 1 is composed of a cover top 3 and a cover edge 4, and the cover edge 4 is composed of a cover along the inner wall and a cover along the outer wall. A V-shaped structure is formed in the longitudinal section along the inner wall and the outer wall of the cover. The tube body 2 is composed of a nozzle 6, a tube tube 7 and a tube bottom 8. The tube tube 7 is a cylindrical structure, so The bottom of the tube 8 is a conical bottom, and the nozzle 6 is composed of the inner wall of the nozzle and the outer wall of the nozzle, and a V-shaped space is formed in the longitudinal section between the inner wall of the nozzle and the outer wall of the nozzle, and the V-shaped The space matches and engages with the V-shaped structure, and the cover top 3 is connected to...

Abstract

The invention discloses a centrifugal tube. The centrifugal tube comprises a tube cover and a tube body, wherein the tube cover comprises a cover top and a cover edge, the cover edge comprises a cover edge inner wall and a cover edge outer wall, a structure with a V-shaped longitudinal section is formed between the cover edge inner wall and the cover edge outer wall, the tube body comprises a tube opening, a tube barrel and a tube bottom, the tube barrel adopts a cylindrical barrel structure, the tube bottom is a conical bottom, the tube opening comprises a tube opening inner wall and a tube opening outer wall, a space with a V-shaped longitudinal section is formed between the tube opening inner wall and the tube opening outer wall, the V-shaped space is clamped with the V-shaped structure in a matched manner, the cover top is connected with the tube opening outer wall through a soft folding structure, the diameter of the opening of the tube opening inner wall is smaller than that of the tube barrel, a bulge is formed on the cover edge outer wall, a dent is formed in the tube opening outer wall and clamped with the bulge in a matched manner, a lining tube is arranged outside the tube body and sealed with the opening of the tube opening outer wall, and a sealed cavity is formed between the lining tube and the tube body. The centrifugal tube solves the problem that samples and the environment are polluted easily.

Description

technical field [0001] The invention relates to a centrifuge tube. Background technique [0002] Today, centrifuge tubes are widely used, especially in life sciences, such as: biochemistry, molecular biology, cell biology, microorganisms, etc. [0003] In education, teaching and scientific experiments, centrifuge tubes are widely used for sample preservation, chemical reaction, biological extraction and separation, strain preservation, cell and microorganism culture, genetic material expansion and translation, etc. [0004] In hospitals, the storage and analysis of biological and chemical samples are also widely used in centrifuge tubes. [0005] Today's centrifuge tube samples are prone to overflow, resulting in inaccurate experimental data, and polluting the sample and the environment. Substances in the external environment are also easy to enter the centrifuge tube and cause sample contamination. Contents of the invention [0006] In order to overcome the deficiencies...
