Cell culture tube structure

Abstract

The invention provides a cell culture tube structure, which is characterized in that a lid and a pipe body are sealed, no liquid overflows from a test tube even under a shaking state, so that subsequent tests can be smoothly carried out. The structure comprises a pipe body and a lid, a downward protruded sealing ring is provided on the upper inner wall of the lid, the outer ring surface of the sealing ring clings to the inner ring surface of the upper end part of the pipe body, an outwards expanding positioning projection is provided at the upper end part of the pipe body, a reversing structure with outwards expanding opening from down to top is arranged on the inner wall of a circular ring guide sleeve of the lid, the upper part of the reversing structure is a guiding ring surface structure, the sealing ring is the structure with the outwards expanding opening from down to top, the guiding ring surface structure clings to the outer ring surface of the positioning projection, and the upper end surface of the pipe body clings to an internal locating surface of the lid.

Description

technical field [0001] The invention relates to the technical field of cell culture structures, in particular to a structure of a cell culture test tube. Background technique [0002] In the existing cell culture test tube, after the cover is installed on the upper end of the tube body, the seal is only completed by the inner sealing ring of the cover being close to the inner ring surface of the upper end of the tube body, while the outer ring of the upper end of the tube body The surface can move relative to the cover, but the seal on only one side is not firm, and the liquid often overflows during shaking. Contents of the invention [0003] In view of the above problems, the present invention provides a structure of a cell culture test tube, which makes the seal between the cover and the tube body good, ensures that no liquid will overflow the test tube even when it is shaken, and ensures the smooth progress of subsequent tests. [0004] A structure of a cell cultur...
