When the protrusions and the grooves come into contact with each other, sound can be generated, to position and control cell air penetrability. The cell culture flask has the advantages that the cell air penetrability can be favorably operated and uniformly controlled and cell growth state can be stabilized.
Description
Technical field
The utility model relates to the cytobiology field, relates in particular to a kind of CO of being applicable to
2The Tissue Culture Flask of incubator.
Background technology
When carrying out cell cultures, zooblast needs constantly to supply with oxygen and get rid of carbonic acid gas, vegetable cell then needs constantly to supply with carbonic acid gas and gets rid of oxygen, thereby Tissue Culture Flask is extremely important to the discharge of the supply of oxygen or carbonic acid gas and carbonic acid gas or oxygen.In existing Tissue Culture Flask, mainly comprise body, bottleneck and bottle cap, but the following problem of ubiquity:
1. most Tissue Culture Flask does not have ventilating structure, it mainly is the circulation of controlling oxygen and carbonic acid gas by the elasticity of control bottle cap, these gas flow are to enter from all slits that bottle cap and bottleneck join, such mode can be supplied with the gas flow of culturing bottle, but air penetrability is difficult to hold, the living environment instability of cell directly causes the instability of cell growth state.
2. existing Tissue Culture Flask is when carrying out cell cultures, be difficult to get hold of the elasticity of bottle cap, during open culture generally unscrewing half-turn degree of being after screwing again, but air permeable effect instability often, medium pH value and osmotic pressure in the cell bottle can't be kept perfect condition; And during airtight cultivation, again often screw socket bottle cap overtorquing, cause the screw socket stripped thread, destroy the stopping property of culturing bottle.
3. there is the bottle cap of some band breather holes on the market, also has the filter membrane of 0.2 m, prevent that culturing cell is contaminated, the invisible rising of scientific research cost.

At the deficiencies in the prior art part, the utility model aims to provide many grades of adjustable Tissue Culture Flasks of screw socket of a kind of even control cell air penetrability.This Tissue Culture Flask can arrange the air penetrability of cell as required, and easy to operate, cell air penetrability is controlled evenly, the growth conditions of stabilized cell.
For achieving the above object, the technical solution of the utility model is:
Many grades of adjustable Tissue Culture Flasks of a kind of screw socket, comprise bottle cap and the bottle that is threaded bottleneck, the screw thread of described screw thread bottleneck is provided with groove or projection, and the screw thread of bottle cap is provided with the projection that is complementary with this groove or the groove that is complementary with this projection.
Be preferably: the outside screw of described screw thread bottleneck is provided with a plurality of grooves or projection, and the internal thread of bottle cap is provided with projection or a groove that is complementary with this projection that is complementary with this groove; Perhaps the internal thread of described screw thread bottleneck is provided with a plurality of grooves or projection, and the outside screw of bottle cap is provided with projection or a groove that is complementary with this projection that is complementary with this groove.
More preferably: the outside screw of described screw thread bottleneck is provided with three grooves, and the internal thread of bottle cap is provided with a projection that is complementary with this groove; First groove a is arranged on the outside screw of first lap, and second groove b is arranged on the outside screw of circle second from the bottom, and the 3rd groove c is arranged on the outside screw terminal point; Described projection is arranged on the zero position of the internal thread of bottle cap.
Also be preferably: the internal thread of described screw thread bottleneck is provided with three projectioies, and the outside screw of bottle cap is provided with a groove that is complementary with this projection; First protruding a is arranged on the internal thread of first lap, and second protruding b is arranged on the internal thread of circle second from the bottom, and the 3rd protruding c is arranged on the internal thread terminal point; Described groove is arranged on the externally threaded zero position of bottle cap.
More preferably: second groove b or second protruding b are arranged on from circle round 180 ° position of screw thread terminal point.
The thickness of described projection is preferred≤1mm.
Below the utility model is made further explanation
Tissue Culture Flask described in the utility model comprises body and bottle cap, and body is provided with bottleneck, and the bottleneck upper end is bottleneck; The screw thread of described screw thread bottleneck is provided with groove or projection, and the screw thread of bottle cap is provided with the projection that is complementary with this groove or the groove that is complementary with this projection; When projection and contact grooves, can send the sound of " clatter ".The cell air penetrability is 50-70% when preferably arranging first grade; The cell air penetrability is 20-40% in the time of second grade; Third gear is for just screwing, and is airtight.
The adjustable design of third gear described in the utility model is applicable to 25cm
2-225cm
2In the culturing bottle of arbitrary specification, no matter torticollis, straight neck.
Compared with prior art, advantage of the present utility model is:
1, thereby Tissue Culture Flask of the present utility model can be controlled the elasticity control oxygen of bottle cap and the circulation of carbonic acid gas by many grades of adjustings, regulates the air penetrability of cell cultures as required, and the control of cell air penetrability is even, the growth conditions of stabilized cell.
2, Tissue Culture Flask of the present utility model can " clatter " sound by last step judges that the screw socket bottle cap tightens, and can not cause the screw socket stripped thread, guarantees the stopping property of culturing bottle.
3, Tissue Culture Flask of the present utility model both can be used as open culture, can be used as airtight cultivation again, and cost is far below the ventilative culturing bottle of import.
