Description
Technical field
The utility model relates to a kind of installation for fermenting, in particular to a kind of laboratory anaerobic fermentation easy device.
Background technique
Anaerobic fermentation refers to organic matter under anaerobic, is decomposed by anaerobic bacteria or facultative anaerobic bacteria and utilizes and generate
The process of certain metabolin.The presence of oxygen is not needed in anaerobic fermentation process, while fermentation process may discharge CO2Equal gas
Body.Therefore, it when carrying out anaerobic fermentation experiment, needs O in Zymolysis Equipment2It is cleared, while may need can be carried out the row of gas
Out.In addition, needing to be sampled fermentation process analysis during the experiment, it is therefore desirable to which anaerobic fermentation equipment can conveniently take
Sample.
Use for laboratory mainly has anaerobism pipe and anaerobic fermentation tank etc. in the device of anaerobic fermentation at present.Anaerobism pipe is one to finish
Hermetically sealed device, but anaerobism pipe is generally only suitable for anaerogenic bacterium of fermenting, and operates more demanding.Although anaerobic fermentation tank
The shortcomings that anaerobism pipe can be overcome, but expensive, complicated for operation, higher operating costs.
Utility model content
The main purpose of the utility model is to provide a kind of laboratory anaerobic fermentation easy device, can effectively solve to carry on the back
The problems in scape technology.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of laboratory anaerobic fermentation easy device, including fermentation flask, the fermentation flask are equipped with closing device, the sealing
Device is equipped with fermentation bung and sampler, and the sampler is one and interts the stainless steel into fermentation flask from rubber stopper
Needle tubing, stainless steel needle tubing upper end are equipped with syringe filter, and the syringe filter upper end is equipped with syringe.
Further, the closing device is rubber stopper, and is sealed between rubber stopper and fermentation flask by paraffin, is guaranteed close
Seal effect.
Further, the fermentation bung is sealed using liquid.
Further, the liquid is the sulfuric acid solution of sterile water or 50% volumetric concentration.
Further, the syringe filter aperture is 0.22 μm or 0.45 μm.
Further, the fermentation flask is vial.
Compared with prior art, the utility model has the following beneficial effects:
A kind of laboratory anaerobic fermentation easy device can guarantee metastable oxygen-free environment, what fermentation process generated
Gas can be discharged in time, can guarantee and fast sample in entire fermentation process and do not enter oxygen, be able to satisfy the anaerobism in laboratory
Fermentation demand.
Detailed description of the invention
Fig. 1 is the utility model laboratory anaerobic fermentation easy device overall structure diagram.
In figure: 1, fermentation flask;2, closing device;3, fermentation bung;4, sampler;5, stainless steel needle tubing;6, needle type filtration
Device;7, syringe.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, a kind of laboratory anaerobic fermentation easy device, including fermentation flask 1, the fermentation flask 1 are vial,
The fermentation flask 1 is equipped with closing device 2, and the closing device 2 is rubber stopper, and passes through paraffin between rubber stopper and fermentation flask 1
Sealing, the closing device 2 are equipped with fermentation bung 3 and sampler 4, and the fermentation bung 3 is sealed using liquid, the liquid
Body is sterile water, and the sampler 4 is one from the interspersed stainless steel needle tubing 5 into fermentation flask 1 of rubber stopper, described stainless
5 upper end of draw point pipe is equipped with 0.22 μm of syringe filter 6, and 6 upper end of syringe filter is equipped with syringe 7.
It should be noted that a kind of working principle of laboratory anaerobic fermentation easy device of the utility model is fermentation bung 3
Sterile water is provided with as sealing solution, closing device 2(rubber stopper) and fermentation flask 1 between further sealed with paraffin, fermentation bung
3, it is also further sealed with paraffin between sampler 4 and rubber stopper, to reach better seal effect.Fermentation bung 3 protrudes into hair
1 upper space of ferment bottle, stainless steel needle tubing 5 access in fermentation flask 1 and are immersed in fermentation liquid level or less;
The gas generated in fermentation process can escape air by fermentation bung 3 and cannot be introduced into, therefore can guarantee to ferment
The microorganism in environment can be effectively prevented to enter in fermentation flask 1 again while equipment and ambient pressure consistency;
In order to further ensure anaerobic state in fermentation flask 1 passes through syringe filter after fermentation inoculation and after sampling
6 and stainless steel needle tubing 5 nitrogen or mixed gas (N are blown into fermentation flask 12、H2、CO2) replacement of oxygen is clean.
When being sampled in fermentation process, syringe filter 6 is removed, hair needed for being drawn from fermentation flask 1 with asepsis injector 7
Zymotic fluid loads onto sterile syringe filter 6 after sampling, then pass through syringe filter 6 and stainless steel needle tubing 5 to fermentation flask 1
In be blown into nitrogen or mixed gas (N2、H2、CO2), then sucking nitrogen or mixed gas (N are packed into syringe filter 62、H2、
CO2) asepsis injector 7 is sealed, guarantee that no oxygen enters in fermentation flask 1 in sampling and fermentation process.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
