A kind of ventilative Tissue Culture Dish
Technical field
The utility model relates to cell cultural technique field, particularly relates to a kind of ventilative Tissue Culture Dish.
Background technology
Culture dish is the glass or the plastic circular vessel that carry out cell/microbial culture for containing liquid medium or solid agar nutrient solution, in view of the stability of glass material, glass culture dish is widely used in experiment or the teaching in the fields such as medical science, microbiology, biomedicine.For cultivation aerobic-type cell, culture dish is needed to carry out gaseous interchange, present this culture dish structure generally comprises culture dish body and mounts cover the culture dish lid on this culture dish body, for making can to realize gaseous interchange between culture dish lid and culture dish body, anchor ring in culture dish lid is provided with rib, this rib press-fits the upper surface in culture dish body, the open to atmosphere gap of the company of leaving between adjacent rib, thus the gap between making by consecutive web completes gaseous interchange.This culture dish structure is comparatively loaded down with trivial details, and rib causes between culture dish lid and culture dish body not fastening, is inconvenient to transport and take.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of ventilative Tissue Culture Dish, and its structure is simple, can prevent internal media from being polluted.
For achieving the above object, the utility model adopts following technical scheme:
A kind of ventilative Tissue Culture Dish, comprise culture dish body and culture dish lid, this culture dish body one end open, described culture dish lid is used for closing the opening of described culture dish body, and described culture dish covers and offers a ventilation hole and for the filtering membrane in enclosed ventilation hole.
Preferably, described filtering membrane is hydrophobic filter membrane.
Preferably, the periphery of the upper surface of described culture dish lid is provided with multiple raised line.
Preferably, the outer side wall of described culture dish body is provided with prominent circle, and the upper surface of described prominent circle contacts with the lower edge of culture dish lid.
Further preferred, the outer side wall of described culture dish body is provided with multiple prominent button, and described prominent button bit is in the top of prominent circle, and described culture dish lid inner side-wall is provided with multiple and prominently detains the catching groove mated.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model offers ventilation hole by covering at culture dish, when cultivating aerobic-type cell, air directly enters from ventilation hole, therefore can close between culture dish lid and culture dish body, ventilation hole is also provided with one deck filtering membrane, nutrient solution can be prevented contaminated.
Accompanying drawing explanation
Fig. 1 is assembling assumption diagram of the present utility model;
Fig. 2 is fractionation structure iron of the present utility model;
Wherein, 1, culture dish body; 11, prominent circle; 12, prominent button; 2, culture dish lid; 21, ventilation hole; 22, filtering membrane; 23, raised line; 24, catching groove.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
See Fig. 1, the utility model provides a kind of ventilative Tissue Culture Dish, it comprises culture dish body 1 and culture dish lid 2, this culture dish body 1 one end is provided with opening, culture dish lid 2 is for closing the opening of described culture dish body 1, culture dish lid 2 mounts cover on culture dish body 1, makes to form an enclosed space between culture dish lid 2 and culture dish body 1, this culture dish lid 2 offers a ventilation hole 21 and for the filtering membrane 22 in enclosed ventilation hole 21.For aerobic-type cell, air can be made to enter by ventilation hole 21, the oxygen supply of aerobic-type cell is provided, and realize the effect of ventilation, filtering membrane 22 enters the pollutents such as the dust of culture dish for filtering out along with air, can prevent the nutrient solution in culture dish and cell from being polluted.This filtering membrane 22 is the hydrophobic filter membrane of sampling preferably, can prevent moisture from entering culture dish from ventilation hole.
The upper surface of culture dish lid 2 is provided with multiple raised line 23, the position of raised line 23 is arranged on the periphery of upper surface, and have gap between adjacent raised line 23, the effect of this raised line 23 is equivalent to stiffening web, the mechanical property of culture dish lid 2 can be improved, strengthen the rigidity of culture dish lid.
On the other hand, specifically see Fig. 2, the outer side wall of culture dish body 1 is provided with prominent circle 11, the prominent upper surface of circle 11 contacts with the lower edge of culture dish lid 2.This prominent circle 11 is equivalent to stack ring, make culture dish lid 2 mount cover the rearmost position after culture dish body 1 can only be defined on this prominent circle 22, or make when designing the upper surface of this prominent circle 22 to the distance on the upper edge of culture dish body 1 equal the height of culture dish lid 2.The outer side wall of culture dish body 1 is provided with multiple prominent button 12, prominent button 12 is positioned at the top of prominent circle 11, culture dish lid 2 inner side-wall is provided with the catching groove 24 that multiple and prominent button 12 mates, when culture dish lid 2 mount cover culture dish body 1 coordinates for cultivating cell time, prominent button 12 mates with catching groove 24 and forms buckle and fix, prevent culture dish in use owing to not fixing between culture dish lid 2 and culture dish body 1 and pollute, and this culture dish is more applicable to transport and takes after fixing.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
