Description
Technical field
The utility model belongs to chemistry teaching fixture fields, and in particular to a kind of microscale laboratory device.
Background technology
Microscale laboratory is the experimental method and technology that required chemical information is obtained with chemical reagent as few as possible,
Have the advantages that small reagent dosage, saving time, seldom or pollution-free and experiment safety are high, can be learnt with training student
The interest and innovative thinking of chemistry, improve student and probe into thinking ability.But due to reagent dosage seldom, experimental ware very little, because
This, gas prepare microscale laboratory in be usually present experimental phenomena not substantially, be difficult observation the shortcomings of.Such as in " dioxy
Change carbon to produce and property " microscale laboratory operation in, often cause the titanium dioxide produced due to reagent dosage seldom
Carbon amounts is very few, so that cause experimental phenomena unobvious, thus, it directly affects the subjective feeling and experiment effect of student.
The content of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of microscale laboratory
Device, by the way that by hand-held technique, data acquisition unit and gas sensor are combined with microscale laboratory gas generator,
Overcome experimental phenomena present in microscale laboratory not substantially, the shortcomings of be difficult observation, and can realize to experimentation
With qualitative, quantitative and " the curve sign " of experimental result.
To achieve the above object, the utility model employs following technical scheme：
A kind of microscale laboratory device, including micro gas generator, the micro gas generator include at least one
Individual chemical reactor and at least one gasoscope；The escaping pipe of the chemical reactor is connected to carefully by ultra-fine rubber tube
The side interface of mouth threeway；The air inlet pipe of the gasoscope is connected to the opposite side of thin mouth threeway by ultra-fine rubber tube
Interface, the upper end interface of thin mouth threeway is connected by ultra-fine rubber tube with having the bottom of branch casing；Set in the tool branch casing
There is the gas sensor being connected with data acquisition unit.
Preferably, the tool branch casing is fixed by sensor fixed rack.
Preferably, the ultra-fine rubber tube（6）Internal diameter be 0.5-3mm, the thin mouth threeway（2）The size of interface internal diameter
With ultra-fine rubber tube（6）Internal diameter size it is corresponding.
As shown from the above technical solution, the utility model use microscale laboratory device, with reagent dosage it is small, section
Save time, reduce or the advantages of pollution-free and high experiment safety, and simple in construction, easy to operate, experimental phenomena is obvious；It is logical
Cross and organically combine hand-held technique and microscale laboratory gas generator, overcome and tested now present in microscale laboratory
As not substantially, be difficult observation the shortcomings of, i.e., on the premise of keeping experiment reagent consumption to drink safety and environmental protection less can substantially, it is accurate
Show experimental result；And hand-held technique is portable, real-time, accurate, directly perceived, it can realize and experimentation and experimental result are determined
Property, quantitative and " curve sign ".
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model includes micro gas generator 1, thin mouth threeway 2, gas sensor 3, is set in
Tool branch casing 7 and data acquisition unit 5 outside gas sensor；Data acquisition unit 5 is connected with gas sensor 3；Gas sensing
Device 3 is placed in tool branch casing 7 and fixed by sensor fixed rack 5.Container in micro gas generator 1 uses penicillin
Bottle, including bottle A, bottle B, bottle C and bottle D；Wherein bottle A is used as chemical reactor；Bottle B, bottle C, bottle D air inlet pipe and escaping pipe according to
It is secondary to connect and compose gasoscope with ultra-fine rubber tube；Bottle A escaping pipe is connected to thin mouth threeway 2 by ultra-fine rubber tube 6
Left side interface；Bottle B air inlet pipe is by being connected to the right side interface of thin mouth threeway 2 by ultra-fine rubber tube 6.Has branch casing
The upper end interface of thin mouth threeway 2 is connected at 7 bottom interface by ultra-fine rubber tube 6.The internal diameter of ultra-fine rubber tube 6 is
1mm, the thin interface internal diameter of mouth threeway 2 is corresponded.
When carrying out chemical test, gas is put into bottle A and is reacted reagent, gas inspection is put into bottle B, bottle C, bottle D
Reaction reagent is tested, bottle cap is covered.The piston of thin mouth threeway 6 is adjusted, the left side interface and upper end interface of thin mouth threeway 6 is connected, beats
Open data acquisition unit 4, you can the change curve that gas is produced is observed on data acquisition unit 4；Then, thin mouth threeway 2 is adjusted
Piston, connect the left side interface and right side interface of thin mouth threeway 6, the gas produced in bottle A is sequentially entered a bottle B, bottle C, bottle D
Middle progress gas property examines experiment.
The utility model is by hand-held technique, and also known as palm technology is configured with data acquisition on micro gas generator
Device, sensor and software kit, can the various common datas of quantitative collection, its most prominent advantage is portable, real-time, standard
Really, intuitively.
Above-described embodiment is only that preferred embodiment of the present utility model is described, not to of the present utility model
Spirit and scope are defined.On the premise of the utility model design concept is not departed from, this area ordinary person is to this practicality
The all variations and modifications that new technical scheme is made, all should drop into protection domain of the present utility model, the utility model
Claimed technology contents, have all been recorded in detail in the claims.
