Abstract
The utility model discloses a kind of acid buret with U-shape structure, it is related to titration outfit technical field, it is dropper mouth at the top of straight tube, bottom connects U-tube, straight tube sets cock with U-tube junction, and U-tube end is water dropper, and dropper mouth is up big and down small funnel-shaped structure, straight tube is transparent pipe, and its side wall sets scale；The utility model makes water dropper away from cock, so that cock remote thermal source in titration process, ensures the accurate of testing result by the design of U-tube；By the design of U-tube, make straight tube and cock away from water dropper, so that straight tube and the cock remote thermal source in titration process, avoid causing operating personnel to scald during take buret and adjustment cock；It is simple in construction, it is easy to operate, it is low into production cost.
Description
Technical field
It the utility model is related to titration outfit technical field, and in particular to a kind of acid titration for being used to detect alcoholic drink mixed with fruit juice total reducing sugar
Pipe.
Background technology
Alcoholic drink mixed with fruit juice is using Spirit, delicate fragrance type Fenyang wine or edible alcohol as wine base, with the animals and plants elite of medicine-food two-purpose, by elder generation
Enter technique to be process, change the alcoholic drink of its former wine base style.In the production process control of alcoholic drink mixed with fruit juice, by total to alcoholic drink mixed with fruit juice
Glycan analysis is detected, and its quality tentatively can be judged.Meanwhile the analysis detection of alcoholic drink mixed with fruit juice total reducing sugar is food security and product matter
The basic demand of amount, and the project that clear stipulaties must be enforced in national standard.
At present, the detection of alcoholic drink mixed with fruit juice total reducing sugar mainly uses Fehlings reagent, and this kind of method of testing is needed in test solution slight boiling condition
Under titrated, experimentation needs to carry out on circuit, and continuous high temperature has a great influence to common acid buret, can make all
Intellectual circle is melted, and influences piston adaptation, causes the inaccurate damage with buret of testing result.Meanwhile in experimentation, it is necessary to
Manual operation, hand take buret and control piston, are easily caused operating personnel's scald.
Utility model content
The utility model is precisely in order to avoid the weak point present in above-mentioned prior art, there is provided one kind is with U-shaped
The acid buret of structure.
The present invention adopts the following technical scheme that to solve technical problem：A kind of acid buret with U-shape structure, straight tube
Top is dropper mouth, and bottom connects U-tube, and the straight tube sets cock with U-tube junction, and the U-tube end is water dropper.
Further, the dropper mouth is up big and down small funnel-shaped structure.
Further, the straight tube is transparent pipe, and its side wall sets scale.
The utility model provides a kind of acid buret with U-shape structure, has the advantages that：
1st, by the design of U-tube, water dropper is made away from cock, so that cock remote thermal source in titration process, ensures
Testing result it is accurate；
2nd, by the design of U-tube, straight tube and cock are made away from water dropper, so that straight tube and cock are remote in titration process
From thermal source, avoid causing operating personnel to scald during take buret and adjustment cock；
3rd, it is simple in construction, it is easy to operate, it is low into production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：
1st, dropper mouth, 2, straight tube, 3, cock, 4, U-tube, 5, water dropper.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that described implementation
Example is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, this area
The every other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to the utility model
The scope of protection.
As shown in figure 1, its structural relation is：The top of straight tube 2 is dropper mouth 1, bottom connection U-tube 4, straight tube 2 and U-tube
4 junctions set cock 3, and the end of U-tube 4 is water dropper 5.
Preferably, dropper mouth 1 is up big and down small funnel-shaped structure.
Preferably, straight tube 2 is transparent pipe, and its side wall sets scale.
When specifically used, comprise the following steps：
1) when detecting sample total reducing sugar, the triangular flask for having added the liquid of the film first and second is placed on hot plate, heating is boiled；
2) filled afterwards three times with prepare liquid rinse buret, leak test, zeroing；
3) methylene blue indicator is added after sample micro-boiling 2min in triangular flask, starts to be titrated with sample, is titrated
When, rate of titration is controlled by cock 3, during color change is terminal in bottle, reads data；
4) by the sample size of consumption, sample total sugar content is calculated.
It should be noted that herein, such as first and second or the like relational terms are used merely to a reality
Body or operation make a distinction with another entity or operation, and not necessarily require or imply and deposited between these entities or operation
In any this actual relation or order.Moreover, term " comprising ", "comprising" or its any other variant are intended to
Nonexcludability includes, so that process, method, article or equipment including a series of elements not only will including those
Element, but also the other element including being not expressly set out, or it is this process, method, article or equipment also to include
Intrinsic key element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that
Other identical element also be present in process, method, article or equipment including the key element.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those within the art that：It still can be to preceding
State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is departed from the spirit and model of various embodiments of the utility model technical scheme
Enclose.
