Abstract
The utility model relates to a microculture device which effectively solves the problems of an existing device that hypoxic degree is inconvenient to control, the operation is complex, pollution is easily caused and the like. According to the technical scheme, the device comprises a common culture box which is internally provided with an oxygen tester, wherein a glass door is arranged in front of the common culture box, a sealing ring is arranged on a glass door frame, the culture box is provided with an oxygen introducing pipeline and a nitrogen introducing pipeline, sealing rings are arranged at the joints between the culture box and the oxygen introducing pipeline, as well as between the culture box and the nitrogen introducing pipeline, the other ends of the oxygen introducing pipeline and the nitrogen introducing pipeline are respectively connected with an oxygen tank and a nitrogen tank and are internally provided with filter membranes, and the oxygen introducing pipeline and the nitrogen introducing pipeline are further sleeved with gas switch valves. The device provided by the utility model is easy to refit, simple and convenient to operate and accurate to control, and the required oxygen concentration can be quickly realized.
Description
Technical field
The utility model relates to experimental installation, particularly a kind of microbial cultivation device.
Background technology
An important step of microorganism culturing is exactly oxygen concentration in the incubator, it all is to carry out under anoxic or the state of hyperoxia that a lot of experiments are arranged, at present the anoxic microbial device mainly contains four classes, is respectively the liquid level closed model, chemical substance is taken oxygen model, three gas incubators and simple and easy capsule mockup by force; And the hyperoxia device mainly contains simple and easy sealed cabin and hyperbaric oxygen chamber; These devices have advantage separately, but still come with some shortcomings, be specially: liquid level closed model operation inconvenience, poor repeatability, now superseded substantially, chemical substance is taken oxygen model good reproducibility by force, comparability is strong, but increased the Confounding Factor of experiment, simple and easy capsule mockup is made simple, and Confounding Factor is few, but inconvenience is controlled the degree of anoxic and might be polluted, three gas incubators can be made desirable anoxia model, but expensive, use complicated, fail at present to promote the use of, hyperbaric oxygen chamber is made the oxygen intoxication model and waste huge and complicated operation under laboratory condition, and simple and easy sealed cabin hyperoxia model can not accurately be controlled oxygen partial pressure, also might pollute.
Summary of the invention
At above-mentioned situation, for overcoming the defective of prior art, the order of the utility model just provides a kind of microbial cultivation device, has effectively solved more existing device inconvenience control degree of oxygen deficiency, complicated operation and problem such as pollute easily.
The technical scheme of its solution is, comprise common incubator, in the common incubator oxygen measuring instrument is housed, the front of common incubator is provided with glass door, glass door frame is provided with sealing-ring, oxygen-supplying tube road and logical nitrogen pipeline are housed on the incubator, incubator and oxygen-supplying tube road and logical nitrogen pipeline junction are provided with sealing-ring, the other end of oxygen-supplying tube road and logical nitrogen pipeline is connected with oxygen canister and nitrogen pot respectively, in oxygen-supplying tube road and the logical nitrogen pipeline filtering membrane is housed, also is set with the gas switch valve on oxygen-supplying tube road and the logical nitrogen pipeline.
The utility model is reequiped easily, and is easy and simple to handle, and control accurately can reach requisite oxygen concentration fast.
Description of drawings
Fig. 1 is the utility model front view.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises common incubator, in the common incubator 1 oxygen measuring instrument 2 is housed, the front of common incubator 1 is provided with glass door, glass door frame is provided with sealing-ring 3, oxygen-supplying tube road 4 and logical nitrogen pipeline 5 are housed on the incubator 1, incubator 1 is provided with sealing-ring 6 with oxygen-supplying tube road 4 and logical nitrogen pipeline 5 junctions, the other end of oxygen-supplying tube road 4 and logical nitrogen pipeline 5 is connected with oxygen canister and nitrogen pot respectively, in oxygen-supplying tube road 4 and the logical nitrogen pipeline 5 filtering membrane 7 is housed, also is set with gas switch valve 8 on oxygen-supplying tube road 4 and the logical nitrogen pipeline 5.
When the utility model uses, common incubator 1 feeds oxygen or the nitrogen of process filter membrane 7 by pipeline, measure oxygen partial pressure in the case by the oxygen measuring instrument 2 that is placed in the common incubator 1, common incubator 1 self can be read partial pressure of carbon dioxide and temperature, kind and the intake velocity of gas switch valve 8 control gases, feed nitrogen when making anoxia model, aerating oxygen when making the hyperoxia model, owing to self have fan in the common incubator 1, can in time stir gas and reach gaseous equilibrium in the incubator fast, and discharge unnecessary gas and avoid the interior normal atmosphere of incubator to increase, and can look at straight by glass door and to read that oxygen divides oxygen in the case, reach accurate control oxygen partial pressure, partial pressure of carbon dioxide and temperature, the purpose of preparation anoxic or hyperoxia.
The utility model is reequiped easily, and is easy and simple to handle, and control accurately can reach requisite oxygen concentration fast.
