Abstract
The utility model discloses a closed multifunctional gas property checking device which aims to solve the problems of large volume of device, long line, and limited application of the miniature gas experimental instrument in the prior art. The device includes a big test tube, a medicine syringe, a rubber plug and a propelling injector, the top of the medicine syringe is fixed with a rubber cap and the side wall thereof is provided with a round hole, the propelling injector is arranged above the round hole, the rubber plug is sleeved outside the medicine syringe, the rubber plug is plugged in the big test tube. The device has the advantages of simple structure principle, convenient use and carrying, environmental protection, less pollution, less consumption of medicine, energy saving, easy operation, more experimental functions, heatable property, good air-tightness, safety, reliability, short time of reaction, low cost.
Description
Technical field the utility model relates to the experimental provision in schools of various levels and categories' chemistry teaching, the particularly a kind of closed Multifunctional, air volume property demo plant that can verify 60 character of 12 kinds of gases.
When background technology was verified the character of gas, the subject matter that exists is at present: 1. drug dosage was big.2. environmental pollution is big.3. the instrument assembling is complicated.4. heavy-polluted gas property is not generally done.5. time-consuming.6. the instrument price is more expensive.There are problems such as device volume is big, route long, application is limited in existing minitype gas experiment instrument.
Utility model content the purpose of this utility model provides a kind of closed Multifunctional, air volume property demo plant, has the problem that device volume is big, route long, application is limited to solve existing minitype gas experiment instrument.
The utility model comprises Boiling tube, medical syringe, rubber stopper, injector, described medical syringe top is fixed with rubber cap, and the sidewall of medical syringe is provided with circular hole, and injector is positioned at the top of circular hole, the medicine syringe jacket has rubber stopper, and rubber stopper is filled in the Boiling tube.
The utility model structural principle is simple, portably uses conveniently, and environmental protection is polluted for a short time, and drug dosage is few, and energy savings is easy and simple to handle, and experiential function is many, can heat, and air-tightness is good, and is safe and reliable, and the reaction time lacks, and cost is low.Can produce 12 kinds of gas (Cl
2, HCl, NH
3, C
2H
2, C
2H
4, HBr, HI, CO
2, CO, H
2S, SO
2, NO
2), can verify 60 character of 12 kinds of gases again, be suitable for the demonstration and the student experimenting of chemical experiment.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings Fig. 1 is a structural representation of the present utility model.
Specific embodiment the utility model comprises Boiling tube 1, medical syringe 3, rubber stopper 5, injector 6, and described medical syringe 3 tops are fixed with rubber cap 2, and the sidewall of medical syringe 3 is provided with circular hole 4, and circular hole 4 is 1-3, is preferably 2.Circular hole 4 is positioned at a side of medical syringe 3, is positioned at a side, and effect has and makes things convenient for syringe add medicine at two: one, and two when keep flat Boiling tube, and the interior medicine of syringe can not flow out.Injector 6 is positioned at the top of circular hole 4, is with rubber stopper 5 outside the medical syringe 3, and rubber stopper 5 is filled in the Boiling tube 1.
Reacting and gas buffer in the medicine syringe 3, is the core component of this device.Injector 6 has cushioning effect, and injector does not need hand push, the pressure of gas oneself control, and key will be controlled the consumption of medicine.Boiling tube 1 selects the hard test tube, and medical syringe 3 can be the medical syringe of all size of recovery.
Except that the confirmatory experiment of reaction needed heating, Boiling tube 1 can exchange in principle with the material of medical syringe 3.
With Cl
2With the reaction of KI/ starch be that the example explanation is if select KMnO
4/ dense HCl produces Cl
2: 1. add a little KI/ starch in medical syringe 3, injector 6 beyond the Great Wall; 2. add a little KMnO in the Boiling tube 1
4/ dense HCl has the medical syringe 3 of rubber stopper 5 as early as possible beyond the Great Wall; 3. produce big yellowish green Cl automatically
2, the Boiling tube 1 that slightly vibrates, the Cl that makes generation
2Fully react with KI/ starch, it is blue that KI/ starch slowly becomes.
Application example of the present utility model sees Table 1.
Table 1
Table one explanation the utility model can be applied to the checking of 60 character of 12 kinds of gases.
