Abstract
The utility model discloses a composite burette which comprises a burette body, wherein the burette body comprises an acid tube body and an alkali tube body; the acid tube body and the alkali tube body are separately arranged; an acid liquid injection hole and an alkali liquid injection hole are formed in the top ends of the acid tube body and the alkali tube body; the acid tube body and the alkali tube body extend outwards along the burette body respectively to be communicated with an acid titrating head and an alkali titrating head respectively; and the acid titrating head and the alkali titrating head are detachably connected with the acid tube body and the alkali tube body respectively. According to the composite burette, the acid tube body and the alkali tube body are designed on the burette body and can be used by people to realize titration at the same time in a test. The acid tube body and the alkali tube body separately work, do not interfere with each other, can be used for titration at the same time, and have independent ranges.
Description
Technical field
The utility model relates to a kind of buret, relates in particular to a kind of combined type buret.
Background technology
Buret is apparatus common in the laboratory, people need use acid buret and base buret in the laboratory, and acid buret and base buret cannot be used with, sometimes need acid titration and the titration of alkali formula to carry out simultaneously in the actual tests, and the buret of prior art has unicity, can only a kind of reagent of splendid attire titration, two kinds of reagent of splendid attire carry out titration simultaneously simultaneously.
The utility model content
According to prior art problem, the utility model discloses a kind of combined type buret, comprise: the buret body, described buret body comprises acid body and alkali formula body, described acid body and alkali formula body branch are arranged, the top of described acid body and alkali formula body has acid liquid injection port and alkali formula liquid injection port respectively, described acid body and alkali formula body stretch out respectively to be communicated with along the buret body respectively and are provided with acid titrating head and alkali formula titrating head, described acid titrating head and alkali formula titrating head respectively with acid body and the releasable connection of alkali formula body.
Described acid body and alkali formula body have extension I and extension II respectively, and described extension I and extension II are threaded with acid titrating head and alkali formula titrating head.
Described extension I and extension II are provided with operation valve I and the operation valve II of control flow rate of liquid.
Has scale mark on described acid body and the alkali formula body.
Because the combined type buret that has adopted technique scheme, the utility model to provide has acid body and alkali formula body, people can use acid body and the titration simultaneously of alkali formula body simultaneously when experimentizing in the design of titration body.And the acid body separates work with alkali formula body, does not disturb mutually, titration simultaneously, and have oneself independent range.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.
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:
Combined type buret as shown in Figure 1 has acid body 7 and alkali formula body 8, and this acid body 7 and alkali formula body 8 independent settings are separately worked, do not disturbed mutually.And acid body 7 and alkali formula body 8 have acid liquid injection port 2 and alkali formula liquid injection port 3, and acid liquid injection port 2 and alkali formula liquid injection port 3 are arc structure all, are conducive to liquid and pour into.Acid body 7 and alkali formula body 8 have dismountable acid titrating head 5 and alkali formula titrating head 6 respectively.
Further, acid titrating head 5 and alkali formula titrating head 6 have extension I11 and extension II12 respectively, and described extension I11 and extension II12 are threaded with acid titrating head 5 and alkali formula titrating head 6.Experimental needs, people can disassemble acid titrating head 5 and alkali formula titrating head 6 and clean.
Further, extension I11 and extension II12 are provided with operation valve I1 and the operation valve II9 of control flow rate of liquid, utilize operation valve can control the flow velocity of liquid.
Further, have scale mark 4 at acid body 7 and alkali formula body 8, utilize scale mark 4 can measure what of titration liquid.
The disclosed combined type buret of the utility model independently is provided with acid body 7 and alkali formula body 8 on buret body 10, make this combined type buret can independently carry out acid base titration simultaneously.The utility model modern design is used simply, 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.
