Abstract
This application discloses a kind of volumetric flask liquid-feeding tube, including enlarged portion, buckling parts, neck, it is characterised in that：The volumetric flask is inflatable liquid-feeding tube with liquid-feeding tube, one reverse valve is set on the outside of the buckling parts, and the length of the neck is more than volumetric flask bottleneck to the length of graduation mark, and the bottom of the neck is horn-like, the bottom of neck is sticked in volumetric flask inside bottle neck, and below graduation mark.By setting liquid-feeding tube on the bottleneck top of volumetric flask, during the liquid relief into volumetric flask and constant volume, drained without using glass bar, it is simple to operate；The design structure of inflatable liquid-feeding tube is simpler, and it is more convenient to install and use.
Description
Technical field
The present invention relates to a kind of capacity utensil, and in particular to the liquid-feeding tube of more convenient volumetric flask constant volume in a kind of chemical experiment.
Background technology
Volumetric flask is a kind of flat bottle of thin neck pyriform, is made up of colourless or brown glass, is to prepare the fine instrument of the accurately solution of certain substance withdrawl syndrome with ground glass stopper or plastic plug.
Volumetric flask used in laboratory at present, bottleneck is too thin, in order to ensure on the non-sticky inwall to volumetric flask graduation mark above section of solution, it need to be drained during inside constant volume liquid relief with glass bar, operate cumbersome, solution is leaked outside with glass bar easy misoperation, certain influence can also be produced on experiment accuracy.
The content of the invention
In view of drawbacks described above of the prior art or deficiency, it is expected to provide a kind of volumetric flask liquid-feeding tube, liquid easily leaks outside during so as to solve constant volume, it is inconvenient for operation the problem of.
The present invention is solves the problems, such as to provide a kind of volumetric flask liquid-feeding tube, including enlarged portion, buckling parts, neck in above-mentioned background technology, it is characterised in that：The volumetric flask is inflatable liquid-feeding tube with liquid-feeding tube, one reverse valve is set on the outside of the buckling parts, after liquid-feeding tube is inflated, volumetric flask bottleneck is fastened by buckling parts to realize the purpose of fixed liquid-feeding tube, the length of the neck is more than volumetric flask bottleneck to the length of graduation mark, the bottom of the neck is horn-like, and the bottom of neck is sticked in volumetric flask inside bottle neck, and below graduation mark.
Further, the volumetric flask is plastic material with liquid-feeding tube, is integrally formed in one.
Further, the volumetric flask may be designed as disposable liquid-feeding tube with liquid-feeding tube.
The technical scheme provided according to the embodiment of the present application, by setting liquid-feeding tube on the bottleneck top of volumetric flask, during the liquid relief into volumetric flask and constant volume, drained without using glass bar, it is simple to operate；The design structure of inflatable liquid-feeding tube is simpler, and it is more convenient to install and use.
