Abstract
The utility model relates to the field of chemical analysis and detection and in particular relates to a trace concentration graduated bottle. The trace concentration graduated bottle is used for concentrating essences and flavors in a laboratory and aims to solve the problems of large solution loss of a volatile concentrated solution which is poured out and measured, poor operability and the like. The trace concentration graduated bottle comprises an elliptic bottle body, wherein a feeding hole is formed in the top of the elliptic bottle body, and the bottom end of the elliptic bottle body is communicated with a transparent tube with graduations. The trace concentration graduated bottle has a reasonable structure and simple construction, is conveniently used, is easy to size liquid to be concentrated, is easy to evaporate in a vacuum rotary evaporator so as to remove a solvent and is simply operated; and with the adoption of the trace concentration graduated bottle, the concentrated solution after the solvent evaporates is conveniently determined without pouring out the liquid to measure, and the loss of a target object is less.
Description
Technical field
The utility model relates to the chemical analysis detection range, is specifically related to a kind of trace and concentrates graduated bottle, can be used for the laboratory and concentrates essence and flavoring agent.
Background technology
At present, in essence and flavoring agent preparation and essence and flavoring agent chemical analysis field, the rotation enrichment facility instrument that is absolutely necessary, and the process that concentrates and effect can produce great influence to the result who analyzes, sometimes Concentrating Process Control is bad even can produce diverse result.Because the content of sample was extremely low during general essence and flavoring agent was analyzed, need to concentrate the liquid of a large amount of volumes, and the concentrate content after concentrating is very little, generally has only 1-3ml, and the bottom area of usual used concentrated bottle is bigger, therefore desirable to the end accurately the volume of concentrate be difficult to, and the volatility concentrate is poured out the solution loss of measurement can be very big, and operability is also poor.
The utility model content
Above-mentioned technical problem to be solved in the utility model provides a kind of trace and concentrates graduated bottle.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of trace concentrates graduated bottle, comprises oval body, and the top of described oval body is provided with charge door, and the bottom of described oval body is communicated with the transparent pipe of band scale.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, simple structure, easy to use, be easy to constant volume solution to be concentrated body, be easy in vacuum rotary evaporator evaporation removing solvent, and the concentrate after the solvent evaporation is convenient to measure, need not liquid is poured out measurement, and simple to operate, the object loss is less.
On the basis of technique scheme, the utility model can also be done following improvement:
Further, described oval bottle is as transparent oval body, and described oval bottle indicates scale on one's body.
Adopt the beneficial effect of above-mentioned further scheme to be: when solvent more for a long time, can see concentrated situation by transparent oval body, more convenient control.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, the parts of each label representative are as follows:
1, oval body, 2, charge door, 3, transparent pipe, 4, the scale of transparent pipe, 5, the scale of oval body.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, a kind of trace concentrates graduated bottle, comprises oval body 1, and the top of described oval body 1 is provided with charge door 2, and the bottom of described oval body 1 is communicated with the transparent pipe 3 of band scale 4.Described oval bottle is as transparent oval body, and described oval bottle indicates scale 5 on one's body.
During concrete operations, the solution to be concentrated of essence and flavoring agent sample to be analyzed is added in the oval body 1, owing on the oval body 1 scale 5 is arranged, volume that can the accurate recording liquid feeding, to concentrate graduated bottle charge door 2 and be connected on the rotary evaporator interface, and begin to concentrate, owing on the transparent pipe 3 scale 4 is arranged, can control concentrated process at any time, till being concentrated to the required usually 1-3ml volume of sample analysis.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. a trace concentrates graduated bottle, comprises oval body, and the top of described oval body is provided with charge door, it is characterized in that: the bottom of described oval body is communicated with the transparent pipe of band scale.
