Abstract

The invention proposes a novel culture dish which comprises a lower cover equipped with an anti-sliding edge and an upper cover which can be sleeved with the lower cover, wherein a circular groove is formed in the periphery in the inner top surface of the upper cover; a seal ring is arranged in the circular groove; a central step hole is formed in the center of the upper cover; a circular ventilation membrane is arranged on the surface of the central step hole; a membrane pressing piece is arranged on the circular ventilation membrane, and is used for tightly pressing the circular ventilation membrane; ventilation holes are formed in the membrane pressing piece. Through the scheme, the circular groove is formed in the periphery in the inner top surface of the upper cover, the seal ring is arranged in the circular groove, and the ventilation holes and the ventilation membrane are arranged on the upper cover, so that the air inside the culture dish can exchange with the outer air, the culture dish has sufficient air, no pollution is caused, and the long-term problem that a sealing film is needed for the culture dish can be solved.

Description

technical field [0001] The invention relates to the field of biological culture devices, in particular to a culture dish. Background technique [0002] At present, most of the plate cultures of cells or tissues such as animals, plants and microorganisms use petri dishes, which are composed of upper cover and lower cover. When in use, put the lid on the culture dish, and then use the sealing film to seal the culture dish, realize the isolation of the environment inside and outside the culture dish, and achieve the sterility of the cultivation process. The main disadvantages are: 1. The application will greatly increase the cost; ②The sealing film cannot be sterilized, and the pollution caused by the bacterial contamination of the sealing film cannot be avoided during long-term use; ③Use the sealing film to seal the petri dish, and wrap the petri dish mouth through the sealing film, which requires multi-layer sealing , Time-consuming and labor-intensive; ④ Difficult to automa...
