Abstract
A kind of photosynthesis experiment instrument, comprise the glass container for filling water and algae, it is characterized in that: described glass container is the vial of thin mouth, the bottle mouth position of described vial is sealed with the plug of band diplopore, diplopore grafting two wireways respectively of described plug, described two wireways are equipped with valve, and wherein a wireway outer end connects oxygen collecting bag, another root wireway outer end is socketed outwardly directed volute spring, and described helical spring inner chamber is for placing the batten of band Mars.Beneficial effect is: only need be placed in the volute spring of another root wireway outer end by the batten of band Mars, Open valve, suitably extruding oxygen collecting bag, and oxygen can on the batten that vial exports to band Mars.Instrument is easy to assembly; The amount of oxygen naked eyes produced are obviously visible; Arrange valve, with how much oxygen just putting how many does not out waste, and a set of experiment instrument can many classes of many experiments, have very high practicality.
Description
Technical field
The utility model relates to a kind of bioconversion medium instrument, particularly photosynthesis experiment instrument.
Background technology
In junior middle school's bioconversion medium, need to prove that photosynthesis can produce oxygen by experiment, the method for employing is: gather some algaes, algae is placed in glass container the water adding 2/3.Algae is covered, the glass test tube of a filled with water that funnel is put upside down with glass funnel.Shine under these things are placed on the sun, you can see bubble rising slowly from algae, enter test tube.After the water in test tube is discharged 2/3, block the mouth of test tube with finger, take out the water surface.With the waddy lighting rear extinguishing, put test tube into, find that waddy rekindles.Prove that in test tube be oxygen.This experiment proves that photosynthesis creates oxygen.
This experiment Problems existing is more, one is operating difficulties, the glass test tube of a filled with water that funnel is put upside down, due to the restriction of glass container internal diameter, palm is difficult to blocking test tube mouth in container, is put in the process on funnel, can flows into some water at test tube, be mixed into some air, cause the oxygen of collection impure.Two is that glass funnel will be placed in glass container the oxygen collecting generation, require that glass container should be circular, funnel is higher, needs the in-built more water of glass container, require that the height of glass container is higher, can lack very much in the lab by the higher bulge of this height.Three is be unfavorable for many experiments of putting into several classes, can only once use in oxygen in test tube, because when whether the gas produced with the batten inspection of band Mars is oxygen, large quantity of air can be entered, the experiment of next class can only be collected again, in fact have to prepare many covering devices and collect oxygen respectively, add the trouble of preparing experiment.
Utility model content
The purpose of this utility model is: for overcoming the problems referred to above, provide a kind of easy to operate, be beneficial to many classes repeat test photosynthesis experiment instruments.
The technical scheme that the utility model adopts is: a kind of photosynthesis experiment instrument, comprise the glass container for filling water and algae, it is characterized in that: described glass container is the vial of thin mouth, the bottle mouth position of described vial is sealed with the plug of band diplopore, diplopore grafting two wireways respectively of described plug, described two wireways are equipped with valve, wherein a wireway outer end connects oxygen collecting bag, another root wireway outer end is socketed outwardly directed volute spring, and described helical spring inner chamber is for placing the batten of band Mars.
The beneficial effects of the utility model are: the oxygen that algae photosynthesis produces can enter oxygen collecting bag, automatically from the growing amount of the known oxygen of bulging degree of collecting bag.During experiment, only need be placed in the volute spring of another root wireway outer end by the batten of band Mars, Open valve, suitably extruding oxygen collecting bag, oxygen can on the batten that vial exports to band Mars.Instrument is easy to assembly; The amount of oxygen naked eyes produced are obviously visible; Arrange valve, with how much oxygen just putting how many does not out waste, and a set of experiment instrument can many classes of many experiments, have very high practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 vial, 2 water, 3 algaes, 4 plugs, the batten of 5 band Mars, 6 volute springs, 7 first valves, 8 first wireways, 9 second wireways, 10 second valves, 11 oxygen collecting bags.
Embodiment
As shown in Figure 1, the first wireway 8 is plugged in plug 4, opens the first valve 7 on the first wireway 8.Second wireway 9 is plugged in plug 4, has been socketed oxygen collecting bag 11 at the end of the second wireway 9, open the second valve 10 on the second wireway 9, flatten collecting bag 11 with deaeration, then close the second valve 10.
As shown in Figure 1, in vial 1, put into algae 3 and fill water, the above-mentioned biforate rubber stopper 4 connecting two wireways being plugged on the bottleneck of vial 1, now needing closedown second valve 10, open the first valve 7, to get rid of too much water, facilitate grafting to operate.For ensureing emptying air as best one can, preferably operate in the underwater of water-butt.
Carry out photosynthesis under the said apparatus connected being placed into sunlight, close the first valve 7, open the second valve 10, make the oxygen of generation enter into oxygen collecting bag 11.
As shown in Figure 1, when needing experiment, volute spring 6 on the cover of the outer end of the first wireway 8, the batten 5 of band Mars is put in the inner chamber of volute spring 6, open the second valve 10 and the first valve 7, suitable extruding oxygen collecting bag 11, oxygen on the batten 5 that vial 1 exports to band Mars, will make it resume combustion.
After experiment, close the first valve 7, open the second valve 10, can continue to collect the new oxygen produced.
