Abstract
The utility model discloses a kind of bacterial detection aerogenesis experiment ball float, comprise the hollow structure of stored-gas in ball float top, the solid bottom of counterweight and for liquid with the passage of gas turnover, it is characterized in that: described ball float is placed in liquid nutrient medium, after substratum is by autoclaving, with pressure change, liquid nutrient medium is full of the hollow structure in top, ball float is sunken to bottom developmental tube, if aerogenesis in the bacteria growth process in hollow structure, gas accumulation is in hollow structure, and liquid nutrient medium is discharged through passage, due to buoyancy, float on liquid nutrient medium liquid level, thus judge test organisms whether aerogenesis.Floating ball structure is simple, effectively prevent voltage regulator tube of the prior art and is inverted in handling process or rocks and namely enter air before use and affect use, while ball float not cracky, reduce cost, the utility model simple operation, improves working efficiency.
Description
Technical field
The utility model relates to the device of bacterial detection aerogenesis, is specifically related to a kind of ball float for the experiment of bacterium aerogenesis.
Background technology
Part bacterium fermenting carbohydrate in growth metabolism process produces gas, this feature Chang Zuowei identifies an index of bacterium, especially coliform, usually in broth culture, place a little voltage regulator tube (also referred to as Du Han Shi pipe), if bacterium is aerogenesis in process of growth, in voltage regulator tube, bacteriogenic gas is gathered in voltage regulator tube top continuously, by observing the gas in little voltage regulator tube, judges whether bacterium can fermenting carbohydrate aerogenesis.Along with popularizing of commercialization instant substratum, still adopt same way, result is in transportation, owing to being inverted or unavoidably rocking, the little voltage regulator tube of the glass in liquid nutrient medium is made namely to enter air before use, even there is breakage, or be attached on the tube wall of loading substratum, make troubles to user of service.
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of bacterial detection aerogenesis experiment ball float being convenient to transport, do not change using method, increase work efficiency.
Summary of the invention
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of bacterial detection aerogenesis experiment ball float, comprise a hollow structure with top inner chamber, bottom solid spheroid and connect the passage of inner chamber, described ball float is placed in test tube or other culture apparatuses, is dipped in liquid nutrient medium.
Above-mentioned ball float, described entirety is circular spheroid, is provided with ellipse or circular hollow structure, hollow structure and ft connection in described top.
Above-mentioned ball float, be solid construction bottom described ball float, centre is provided with the passage of hollow structure in connection top, bottom.
Above-mentioned ball float, material is polypropylene (PP), polyethylene (PE), silica gel, glass or other materials, and density is 1.1-2.6 × 103kg/m3, high temperature resistant 120-150 degree Celsius.
Above-mentioned ball float, diameter is 5mm-10mm.
Above-mentioned ball float is whole clearing, translucent, or opaque.
Above-mentioned ball float is colourless or other colors.
The utility model bacterial detection aerogenesis experiment floating ball structure is simple, after being placed in instant finished product substratum, the circular configuration that top and bottom varies in weight, effectively ensure that in handling process and make voltage regulator tube enter air before use because being inverted or rocking and affect use, top hollow structure is beneficial to assembles bacterium institute aerogenesis body, spheroid is made to float on substratum liquid level, improve the judgement of aerogenesis experimental result, the simultaneously spheroid of not cracky, reduce cost, the utility model simple operation, improves working efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model bacterial detection aerogenesis experiment ball float shape assumption diagram.
Fig. 2 is full sectional view before the experiment of the utility model bacterial detection aerogenesis.
Fig. 3 is full sectional view after the utility model bacterial detection aerogenesis.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details:
As shown in Figure 1, a kind of ball float of bacterial detection aerogenesis, comprises the passage 3 of hollow structure 2, solid bottom 1 and the liquid inlet and outlet spheroid arranged in top.As shown in Figure 2, during use, ball float is put into liquid nutrient medium, after substratum is by autoclaving, the air in spheroid hollow structure 2 is discharged, and liquid nutrient medium enters in sphere structure 2 by passage 3, make spheroid calm bottom developmental tube, because bottom density is greater than top, ensure that the direction of ball float, namely perforated bottom down.As shown in Figure 3, in aerogenesis experiment, if bacterium aerogenesis, then gas is gathered in floating ball structure 2 continuously, liquid nutrient medium is discharged from passage 3, and because the gas density in spheroid top hollow structure 2 is less than liquid nutrient medium, buoyancy makes spheroid slowly float.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present utility model, the change made, remodeling, interpolation or replacement, all should belong to protection domain of the present utility model.
Claims (4)
1. a bacterial detection aerogenesis experiment ball float, comprises one and has top hollow structure inner chamber, bottom solid spheroid and connect the passage of inner chamber; It is characterized in that: described ball float is placed in liquid nutrient medium, be sunken to bottom developmental tube before experiment, float on liquid nutrient medium liquid level after test or be still sunken to bottom developmental tube, judge test organisms whether aerogenesis according to ball float suspension situation.
2. ball float according to claim 1, is characterized in that: be provided with cavity-like hollow structure in described ball float top.
3. ball float according to claim 2, is characterized in that: described ball float arranges bottom for solid sphere.
