Abstract
A flame reaction display device relates to the technical field of chemical teaching aids. The flame reaction display device comprises a rustless wire helical coil and a disposable injector, wherein a connection steel wire is welded on the rustless wire helical coil, and a fixing clip is welded at the other end of the connection steel wire; and the fixing clip is connected to the needle head of the injector in a sleeved manner. Compared with the prior art, the flame reaction display device provided by the utility model has the following advantages: liquid inside an injector is transported to the helical coil by pushing the injector, the flame reaction area is large, flame reaction of corresponding metallic elements can be observed obviously, the structure is simple, and the flame reaction display device is a chemical demonstration teaching aid which has a popularization value.
Description
Technical field
The utility model relates to the technical field of chemical lecture experiment, is a kind of flame reaction exhibiting device specifically.
Background technology
In the discriminating of explanation metallic element ion, need the discriminating of explanation sodion and potassium ion, also need explain the principle of fireworks; The flame reaction how can more significantly show some salt solusions, what adopt on the teaching material is that the method that the metal platinum filament picks liquid to be measured is carried out DeGrain; And the costing an arm and a leg of metal platinum filament, be unfavorable for popularizing, how to carry out the displaying of flame reaction; Make phenomenon more obvious, also do not have better method at present.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides a kind of and can obviously show the demonstration device of flame reaction, promptly a kind of flame reaction exhibiting device.
The purpose of the utility model realizes through following technological means: a kind of flame reaction exhibiting device; Form by rustless iron wire helical disk and disposable syringe; Be welded with the connection steel wire above the said rustless iron wire helical disk, connect the steel wire other end and be welded with fixed card; Fixed card is socketed on the syringe needle.
Compared with prior art the utlity model has following tangible advantage: can the liquid in the syringe be passed on the helical disk through injecting love dart; The flame reaction area is big; Can significantly observe the flame reaction of corresponding metallic element; Simple in structure, be a kind of chemical demonstration teaching aid that promotional value is arranged very much.
Description of drawings
Fig. 1 is the utility model overall schematic;
Fig. 2 is the local enlarged diagram of the utility model.
Wherein 1. rustless iron wire helical disks 2. connect steel wire, 3. fixed card, 4. syringe needle, 5. syringe tube.
Embodiment
Below in conjunction with description of drawings the utility model is done further to describe in detail:
The use of this a kind of flame reaction exhibiting device is: draw liquid to be measured with syringe tube 5; Fixed card 3 is fixed on the syringe needle 4; The liquid that syringe needle is come out is just wandered on rustless iron wire helical disk 1; Rustless iron wire helical disk 1 is placed on calcination on the spirit lamp flame, observes, can see the flame reaction of corresponding liquid.If (flame reaction of potassium element will see through blue cobalt glass and observe) can also observe simultaneously in pushing syringe handle realization sustained combustion, burning area is big, and phenomenon is obvious.
In a word, the utility model provides a kind of flame reaction exhibiting device.The above; Be merely a part of embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
