External diameter 83.6～83.8mm at the bottom of the described culture dish, internal diameter 81.2～81.4mm, high 17.7～17.9mm; Outer wall has three trapezoidal plates that are evenly distributed at the bottom of the culture dish, as inner bayonet, cooperates with the outer bayonet of culture dish lid; Select PC as making material at the bottom of the culture dish.
Described culture dish sealing-ring external diameter 87.5～87.7mm, internal diameter 79.8～80.0mm, thick 1.1～1.3mm; Sealing-ring has three bayonet slot, cooperates with inner bayonet at the bottom of the culture dish; Sealing-ring selects silica gel as making material.
Described culture dish air filter is comprised of air-filtering membrane and pressuring film plate.Air-filtering membrane diameter 15～17mm, aperture 0.21～0.23 μ m of film; Pressuring film plate diameter 15～17mm, thickness is 1.2～1.4mm, equally distributed 6 scallop holes is arranged, as ventilating pit on the pressuring film plate; Air filter is loaded on the centre portions of culture dish lid.Air-filtering membrane selects cellulose acetate membrane as making material, and pressuring film plate selects PC as making material.
During use, by spiral cover, the trapezoidal plate of the outer bayonet of culture dish lid inwall snaps in the trapezoidal plate of the inner bayonet of outer wall at the bottom of the culture dish, and culture dish lid and chucking at the bottom of the culture dish are ventilative by ventilating pit in the culture dish.
A kind of spiral cover of the utility model culture dish of breathing freely, by the application of sealing-ring, ventilating pit and air-filtering membrane, making has sufficient air in the culture dish, and the culture in the culture dish is not subjected to atmospheric pollution, efficiently solve the airtight plant tissue growth that affects, the ventilative problem of polluting that increases; The ventilative culture dish of spiral cover needn't seal with sealed membrane when using, and seals the problem that different operating personnel sealing effectiveness there are differences with sealed membrane when having avoided general culture dish to use.Simultaneously, solve the problem of using the cellar culture ware easily to pollute in cell or tissue long-term cultivation processes such as animals and plants and microorganisms, be conducive to the batch production production application.The ventilative culture dish of a kind of spiral cover of the utility model can be used for the cultivation of the tissue such as plant, animal, microorganism and cell, and is with a wide range of applications.
