Abstract
The utility model discloses a bottle cap device for eggplant bottle slant culture, which comprises a bottle cap, wherein the bottle cap is in threaded fit with a bottle opening of an eggplant bottle; the bottle cap is provided with an air pipe in a penetrating way, one end of the air pipe extends into the eggplant bottle, and the other end of the air pipe is sequentially connected with a silica gel hose and a needle filter in series; the bottle cap in threaded fit ensures the sealing of the bottle mouth, the air pressure in the eggplant bottle is balanced with the external air pressure through the air pipe, the silica gel hose and the needle filter, the air permeability of the eggplant bottle is ensured, the oxygen supply capacity is improved, and therefore the requirement of microbial culture with large oxygen demand is met.
Description
Technical Field
The utility model relates to the technical field of microorganism culture apparatus, in particular to a bottle cap device for eggplant bottle slant culture.
Background
Eggplant bottle slant culture is a common strain vessel culture means in the field of microorganisms, and at present, the bottleneck of an eggplant bottle is generally closed by a rubber plug or a cotton plug, so that the defect of poor air permeability is caused, and the microbial culture with large oxygen demand cannot be effectively met.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bottle lid device for eggplant bottle inclined plane is cultivateed, the device can guarantee the gas permeability of eggplant bottle when sealing the bottleneck, improves the oxygen suppliment ability, satisfies the microbial cultivation that the oxygen demand is big.
The utility model provides a technical scheme that its technical problem adopted is:
a bottle cap device for eggplant bottle slant culture comprises a bottle cap, wherein the bottle cap is in threaded fit with a bottle opening of an eggplant bottle; the bottle cap is provided with an air pipe in a penetrating way, one end of the air pipe extends into the eggplant bottle, and the other end of the air pipe is sequentially connected with the silica gel hose and the needle filter in series.
The beneficial effects of the utility model are that, the closure of bottleneck is guaranteed to screw-thread fit's bottle lid, through trachea, silica gel hose and syringe needle filter, makes eggplant bottle internal gas pressure balanced with external atmospheric pressure mutually, guarantees the gas permeability of eggplant bottle, improves the oxygen suppliment ability to satisfy the microbial cultivation that the oxygen demand is big.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the utility model provides a bottle cap device for eggplant bottle slant culture, which comprises a bottle cap 1, wherein the inner wall of the bottle cap 1 is provided with an internal thread, the mouth of the eggplant bottle 2 is provided with an external thread, and the bottle cap 1 is in threaded fit with the mouth of the eggplant bottle 2; the bottle lid 1 is provided with an air pipe 3 in a penetrating way, one end of the air pipe 3 extends into the eggplant bottle 2, the other end of the air pipe is connected with a silica gel hose 4, one end of the silica gel hose 4 is connected with the air pipe 3, and the other end of the silica gel hose is connected with a needle filter 5.
