Abstract

The invention discloses a sealed culture dish which comprises a dish bottom and a dish cover which can be tightly buckled with the dish bottom, wherein the dish bottom comprises a bottom wall and dish bottom side walls; the dish cover comprises a cover wall and dish cover side walls; friction sealing devices are arranged on contact surfaces of the dish bottom side walls and the dish cover side walls, so that the air tightness of the contact surfaces can be defined. Through holes or small holes are formed in the cover wall, a micro-hole filtering membrane and a hole plug are arranged in the through hole, or a filter is arranged in the small hole through a leather collar, a structure defined according to the condition is used as a gas exchange channel, the stability of an air component in a cavity of the culture dish is maintained, the balance of internal and external air pressure is maintained, the burst of the dish bottom and the dish cover is prevented, air flowing through can be filtered, a harmful gas solution such as thallus or spore of pathogenic microorganisms in the culture dish is prevented from passing or diffusion pollution, and the security of operators is ensured.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a closed culture dish. Background technique [0002] Petri dishes are one of the most commonly used experimental equipment in biology, and are widely used in the cultivation of microorganisms and the passage of tissue cells. Currently, commonly used petri dishes generally include a dish bottom and a dish cover loosely covering the dish bottom. The inner cavity is used as a culture space. Place the Petri dish in an incubator with adjustable temperature and humidity to establish optimal conditions for culture growth. The air in the incubator has a defined oxygen and carbon dioxide content, and the loosely supported lid allows gas exchange between the chamber cavity and the incubator air. However, when the lid of the dish is opened or the air outside the petri dish flows, it may cause turbulence in the air in the petri dish, and then the aerosol (including mist-like small liquid or sma...
