Abstract
The utility model discloses a separate-type burette which comprises a burette body and a titrating head for use in combination with the burette body, wherein the titrating head is detachably connected with the burette body; one end of the burette body is provided with a filling funnel; one end of the filling funnel is connected with a storage can; the filling funnel is communicated with the storage can; the side wall of the tail end of the burette body is provided with external threads, and the side wall of one end of the titrating head is provided with internal threads matched with the external threads; and the burette body and the titrating head are in threaded connection. Due to adoption of the technical scheme, the separate-type burette disclosed by the utility model has the beneficial effects that the burette and the titrating head are designed to be detachable from each other, so that the burette is convenient to wash, and the shortcoming that a traditional burette is often damaged due to mixed use of acid and alkaline substances is overcome. Due to a simple structure, the burette is not only convenient to produce, but also very low in cost, and suitable to be widely popularized.
Description
Technical field
The utility model relates to experiment equipment, relates in particular to a kind of separate type buret.
Background technology
In chemical experiment, buret is the experiment apparatus of using always, especially carries out in the acid-base neutralization reaction.People often use acid buret and base buret, because two kinds of burets of difference of potential of hydrogen can not be used with, if the phenomenon of using with will shorten serviceable life, the especially titrating head of buret, because flushing is not thorough, are easy to damage.
The utility model content
Problem according to prior art exists the utility model discloses a kind of separate type buret, comprises buret body and the titrating head that is used with this buret body, described titrating head and the releasable connection of buret body;
One end of described buret body has the liquid of filling funnel, and an end of described filling liquid funnel is connected with fluid reservoir, and described filling liquid funnel is connected with fluid reservoir.
The terminal sidewall of described buret body has external thread, and a distolateral wall of described titrating head has the internal thread that matches with external thread, and described buret body is threaded with titrating head.
Be provided with buffering ball in the described filling liquid funnel.
On the described buret body, the below of fluid reservoir is provided with operation valve I.
Be provided with auxiliary liquid injection pipe between described filling liquid funnel and the fluid reservoir, described auxiliary liquid injection pipe is connected with the buret body.
Be provided with operation valve II between described auxiliary liquid injection pipe and the buret body.
The sidewall of described buret body is provided with scale mark.
Because a kind of separate type buret that has adopted technique scheme, the utility model to provide is designed to detachable structure with buret and titrating head, make its flushing convenient, overcome traditional buret because soda acid is used frequent impaired phenomenon with.Because it is simple in structure, not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, the accompanying drawing that describes below only is some embodiment that put down in writing among the application, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model titrating head.
Fig. 3 is buret pipe structure synoptic diagram of the present utility model.
Among the figure: 1. buret body; 11. external thread; 12. scale mark; 2. titrating head; 21. internal thread; 3. irritate the liquid funnel; 31. buffering ball; 4. fluid reservoir; 5. assist liquid injection pipe; 6. operation valve II; 7. operation valve I.
Embodiment
For making the technical solution of the utility model and advantage clearer, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is known complete description:
Separate type buret as shown in Figure 1, have buret body 1 and titrating head 2, because buret body 1 and 2 detachable connections of titrating head, buret body 1 namely can be adorned acid reagent in use, can adorn basic reagent again, only buret body 1 cleaning down need get final product, when the different reagent of titration, only need a replacing titrating head 2 to get final product.
Be illustrated in figure 3 as the structural representation of buret body 1, the upper end of this buret body 1 has the liquid of filling funnel 3, fluid reservoir 4, solution enters in the fluid reservoir 4 from irritating liquid funnel 3, if in the time of need stopping to test when carrying out titration, can utilize operation valve I7 to control, make solution stop to flow downward.
Further, as shown in Figures 2 and 3, has external thread 11 at the sidewall of buret body 1 end, sidewall at titrating head 2 has internal thread 21, titrating head 2 is screwed on the buret body 1 by internal thread 21 and external thread 11, makes its convenient disassembly when changing titrating head 2, is beneficial to replacing.
Further, irritate in the liquid funnel 3 and be provided with buffering ball 31, when in filling liquid funnel 3, pouring solution into, make solution flow rate slow owing to have buffering ball 31.
Further, irritate and to be provided with auxiliary liquid injection pipe 5 between liquid funnel 3 and the fluid reservoir 4, in use, if according to the needs of actual conditions, can inject solution by auxiliary liquid injection pipe 5.Between auxiliary liquid injection pipe 5 and buret body 1, be provided with operation valve II6.
Further, the sidewall of described buret body 1 is provided with scale mark 12.
The disclosed separate type buret of the utility model, buret body 1 and titrating head 2 are designed to the detachable structure, because its fractionation is simple and convenient, when buret needs to adorn different reagent titration in use, only needs flushing buret body 1 and change titrating head 2.This separate type buret modern design, simple in structure, can be widely applied in the laboratory.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
