a centrifuge tube

Abstract

The invention discloses a centrifugal tube. The centrifugal tube comprises a tube cap and a tube body, wherein the tube cap is composed of a cap top and a cap edge, the cap edge is composed of a cap edge inner wall and a cap edge outer wall, a structure with a V-shaped longitudinal section is formed between the cap edge inner wall and the cap edge outer wall, the tube body is composed of an orifice, a tube cylinder and a tube bottom, the tube cylinder is of a cylindrical structure, and the tube bottom is conical; the orifice is composed of an orifice inner wall and an orifice outer wall, a space with a V-shaped longitudinal section is formed between the orifice inner wall and the orifice outer wall, and the V-shaped space and the V-shaped structure are matched and clamped together; the cap top is connected with the orifice outer wall through a flexible folded structure, and the diameter of the opening portion of the orifice inner wall is smaller than that of the tube cylinder; an insertion piece is arranged on the inner side of the orifice outer wall, an insertion groove is formed in the outer wall of the cap edge, the opening of the insertion groove becomes wider from top to bottom, a lining sleeve is arranged outside the tube body, the lining sleeve and the opening portion of the orifice outer wall are sealed, and a sealed cavity is formed between the lining sleeve 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...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a centrifuge tube, which makes the engagement more tightly through the V-shaped contact surface of the tube cover and the tube body, and solves the problem that the sample and the environment are easily polluted
