Background technology

Biological lesson of middle school has an experiment, name is called " probing into saccharomycetic breathing pattern ", this experiment is based on following three principles: 1, saccharomycete is a kind of unicellular fungi, under the condition of aerobic and anaerobic, can both survive, belong to facultative anaerobe, therefore be convenient to be used for studying the different modes of cellular respiration; 2, CO ₂Can make clarification limewash become muddy, also can make the bromothymol blue aqueous solution by the green flavescence again of blue stain, the time length according to muddy degree of limewash or bromothymol blue aqueous solution yellowing can detect saccharomycete and cultivate CO ₂Production; Chemical reaction takes place with ethanol (alcohol) in 3, orange potassium bichromate solution under acid condition, under acid condition, become celadon.Use Drexel bottle, fermentation flask and detection bottle according to the designed experiment needs of this principle, wherein Drexel bottle is used to remove airborne CO ₂, eliminate airborne CO ₂To the influence of experiment, fermentation flask is used for the culture yeasts bacterium, detects bottle and is used to detect the gas that the culture yeasts bacterium produces.Under the aerobic conditions, need use Drexel bottle, fermentation flask and detection bottle simultaneously, next need of oxygen free condition are used fermentation flask and are detected bottle.And also to from fermentation flask, extract nutrient solution in the experimentation, whether produce alcohol to detect.

As seen, each vial that is used for this type of Bioexperiment will connect with conduit usually, and has different connection combinations, and the vial that has also will be convenient to therefrom extract sample liquid.In the prior art, each vial adopts rubber stopper or stopper sealing, adopts the glass tube two ends of " Jiong " font to insert the connection that realizes two vials in the plug of two vials respectively.Shortcomings such as this mode has operation inconvenience, sealing is bad, experimental result is not accurate enough, and bottle stopper and grass tube be after dismounting repeatedly, and sealing property can greatly reduce, even can't use.

Summary of the invention

Shortcomings such as the utility model provides a kind of Bioexperiment device, and its main purpose is to overcome existing Bioexperiment device operation inconvenience, sealing is bad, experimental result is not accurate enough.

The utility model adopts following technical scheme: a kind of Bioexperiment device, at least comprise a main bottle body, this main bottle body has a bottleneck, described bottleneck top is provided with a bottle stopper, bottleneck is combined with a bottle cap, this bottle cap madial wall is connected by threaded engagement with the bottleneck periphery wall, and this bottle cap is pressed in bottle stopper on the bottleneck; Described bottle cap end face offers the opening that bottle stopper is partly exposed, and the exposed parts of this bottle stopper is inserted with air inlet pipe, escape pipe and probe tube, and this probe tube top is provided with the seal cover of its sealing.

Aforementioned a kind of Bioexperiment device, comprise that also first assists bottle, the auxilliary bottle of this first has a bottleneck, and its bottleneck top is provided with a bottle stopper, and bottleneck is combined with a bottle cap, this bottle cap madial wall is connected by threaded engagement with the bottleneck periphery wall, this bottle cap is pressed in bottle stopper on the bottleneck, and this bottle cap end face offers the opening that bottle stopper is partly exposed, and the exposed parts of this bottle stopper is inserted with air inlet pipe, and offering steam vent, this air inlet pipe is connected by flexible pipe with the escape pipe of described main bottle body.

Further, can comprise that also second assists bottle, the auxilliary bottle of this second has a bottleneck, and its bottleneck top is provided with a bottle stopper, and bottleneck is combined with a bottle cap, this bottle cap madial wall is connected by threaded engagement with the bottleneck periphery wall, this bottle cap is pressed in bottle stopper on the bottleneck, and this bottle cap end face offers the opening that bottle stopper is partly exposed, and the exposed parts of this bottle stopper is inserted with air inlet pipe and escape pipe, this escape pipe is connected by flexible pipe with the air inlet pipe of described main bottle body, and this air inlet pipe is connected by flexible pipe with air pump.

By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, bottleneck adopts bottle cap to screw the mode that compresses bottle stopper and realizes sealing, good seal performance, the dismounting of this structure convenient bottle stopper is not through repeatedly influencing sealing property after the dismounting yet; Two, fixedly plug air inlet pipe, blast pipe on the bottle stopper, be connected to each other with flexible pipe again, also can improve the sealing property of connection, be convenient to dismounting.
