Abstract
A novel experiment device is mainly composed of a fermentation bottle, a detection bottle and a gas washing bottle. The bottlenecks of the fermentation bottle, the detection bottle and the gas washing bottle are all frosted bottlenecks. The bottle stopper of each bottle is tightly pressed on the bottleneck by the bottle cap of each bottle. The inside wall of each bottle cap is connected with the circumferential wall outside each bottleneck in a screw thread manner. A seal cover is disposed on the top of a sampling pipe. The lower end of the sampling pipe passes through the bottle stopper to be inserted into the fermentation bottle. A vent hole is arranged on the upper side of the detection bottle. The vent hole is provided with a valve. The bottle stopper of each bottle is tightly pressed on the bottleneck by the bottle cap of each bottle for sealing with a fine sealing performance. The frosted structure is adopted by each bottle for the convenience in mounting and dismounting the bottle stopper, and the sealing performance is not affected even though the bottle stopper is mounted and dismounted many times. The novel experiment device is convenient in mounting and dismounting, reasonable in structure and design, ingenious and novel in conception, and safe and reliable, and is easy for large scale promotion and application.
Description
Technical field
The utility model relates to a kind of novel experimental provision, is the used a kind of teaching aid of Bioexperiment class.
Background technology
Biological class has an experiment; Name is called " probing into saccharomycetic breathing pattern ", and 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 can make clarification lime water become muddy, also can make the bromothymol blue WS by the green flavescence again of blue stain, and the time length according to muddy degree of lime water or bromothymol blue WS yellowing can detect the production that saccharomycete is cultivated CO; 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 experiment needs that this principle designed, 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 yeast bacterium, detects bottle and is used to detect the gas that the culture yeast 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.It is thus clear that each vial that is used for this type of Bioexperiment will connect with conduit usually, and have different connection combinations, the vial that has also will be convenient to therefrom extract a kind liquid.In the prior art, each vial adopts rubber stopper or stopper sealing, adopts the glass tube two ends of " door " font to insert the connection that realizes two vials in the glass bottle stopper 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
The purpose of the utility model provides a kind of novel experimental provision, has solved the problem of sealing effectiveness difference, has avoided the big difficult problem of experimental error.
The purpose of the utility model realizes as follows: it mainly is made up of fermentation flask, detection bottle and Drexel bottle; The bottleneck of fermentation flask, detection bottle and Drexel bottle is Scrub, and bottle cap is pressed in bottle stopper on the bottleneck, and this bottle cap madial wall is connected through threaded engagement with the bottleneck periphery wall; The stopple coupon top is provided with gland bonnet; The stopple coupon lower end is passed bottle stopper and is inserted fermentation flask, detects bottle upper end one side and is provided with air hole, and valve is housed on the air hole; First escape pipe, one end inserts the Drexel bottle other end and is fixedly connected with first draft tube on the fermentation flask, and second draft tube that second escape pipe, one end inserts in the fermentation flask other end and the detection bottle is fixedly connected.
The utility model is the used a kind of teaching aid of Bioexperiment class, and the mode that bottleneck adopts bottle cap to compress bottle stopper realizes sealing, good seal performance; The dismounting of Scrub structure convenient bottle stopper; After repeatedly dismantling, can not influence sealing property yet, reasonable in design, novelty is skillfully constructed; Safe and reliable, and be easy to large-scale promotion application.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
With reference to accompanying drawing; This novel experimental provision mainly is made up of fermentation flask 10, detection bottle 12 and Drexel bottle 2; The bottleneck of fermentation flask 10, detection bottle 12 and Drexel bottle 2 is Scrub, and bottle cap 3 is pressed in bottle stopper 9 on the bottleneck 4, and these bottle cap 3 madial walls are connected through threaded engagement with bottleneck 4 periphery walls; Stopple coupon 6 tops are provided with gland bonnet 7; Stopple coupon 6 lower ends are passed bottle stopper 9 and are inserted fermentation flask 10, detect bottle 12 upper ends one side and are provided with air hole 13, and valve 14 is housed on the air hole 13; First escape pipe, 1 one ends insert Drexel bottle 2 other ends and are fixedly connected with first draft tube 5 on the fermentation flask 10, and second draft tube 11 that second escape pipe, 8 one ends insert in fermentation flask 10 other ends and the detection bottles 12 is fixedly connected.Under aerobic conditions, 10% NaOH solution is housed in the Drexel bottle 2, the saccharomycete nutrient solution is housed in the fermentation flask 10; Detect in the bottle 12 lime water is housed; The draft tube of Drexel bottle 2 connects rubber ball, let air be interrupted and constantly successively through fermentation flask 10, detect bottle 12 and Drexel bottle 2, both guaranteed O
2Ample supply, make the air that gets into fermentation flask 10 earlier through the airborne CO of Drexel bottle 2 eccysis of NaOH again
2, guaranteeing that the lime water of the clarification of detection bottle 12 becomes muddy, this is because the CO of saccharomycete aerobic respiration generation
2Due to.Under oxygen free condition,, treat saccharomycete O in fermentation flask 10 with first draft tube sealing a period of time
2Be consumed, be communicated with the detection bottle 12 that fills clarification lime water again, guaranteed it is the CO that anaerobic respiration produces
2Feed the lime water of clarification, it is muddy that the lime water of clarification still becomes.
