Description
Technical field
The utility model relates to a kind of experiment equipment, particularly a kind of closed culture dish.
Background technology
Culture dish is one of experiment equipment the most frequently used in biology, and be widely used in the cultivation of microorganism, histiocyticly go down to posterity, culture dish conventional at present generally comprises at the bottom of ware and the lax ware lid be covered at the bottom of ware, and the two inner chamber formed is as culture space.Culture dish is inserted in the incubator of a temperature-adjustable, humidity, to set up the top condition of culture growth.Air in incubator has the oxygen and carbon dioxide content determined, and the lax ware lid supported allows the air of culture dish inner chamber and incubator to form gaseous interchange.But, when opening ware lid or culture dish flow of external air, the turbulent flow of air in culture dish may be caused, and then make the gaseous solution suspended in air in culture dish (comprise vaporific little liquid or solid granule etc., thalline or spore, gemma etc. as microorganism) air release towards periphery, pollute surrounding environment, this is at cultivation pathogenic microorganism or especially dangerous when producing ectotoxic cell, and therefore user also may bear Health hazard.
CN101875902 B discloses a kind of Tissue Culture Dish, to comprise at the bottom of a ware and sealing is placed in ware lid on ware downside wall, and ware lid and the contact surface at the bottom of ware are friction lock locking devices, and the sealed state of formation can by the bore seal of culture dish.This culture dish is also provided with ventilation gap in addition, and under ventilation state, ventilation gap can as the passage of gaseous interchange inside and outside culture dish.Ventilation state and sealed state can be exchanged easily by manual shift, to adapt to the demand of different culture condition.But, the sealed state of this Tissue Culture Dish and ventilation state cannot be changed automatically, and when culture dish is in sealed state, inside and outside culture dish, the exchange of gas is completely blocked, this may affect the normal growth breeding of culture in culture dish, particularly aerobic microorganism.In addition when the culture dish being in sealed state is for cultivating the larger microorganism of some gas production rate, the gas that bacteria metabolism produces will make culture dish internal gas pressure raise gradually, and then cause at the bottom of ware and the explosion of ware lid, and the splashing of culture or substratum in culture dish, thus cause the failure of cultivation and pollute on a large scale.
The culture dish product tackiness agent had in addition by close adhesion removable at the bottom of ware lid and ware, to form the space of culture dish internal independence, sealing.But through storing for a long time, after the cultivation of different temperature and humidity conditions or autoclave sterilization, the characteristic of tackiness agent may change, thus affects its sealing effectiveness.The internal substance of tackiness agent also may pollute substratum, affects the growth of culture in culture dish.The culture dish of adhesive seal also prevents the exchange of gas inside and outside culture dish, also may affect aerobic microbial growth in culture dish or cause at the bottom of ware and the explosion of ware lid, the splashing of culture and substratum in culture dish.
