Abstract
The utility model relates to a short neck horn-shaped flaring volumetric flask which is composed of a flask stopper and a flask body. The flask stopper and a flask mouth at the upper end of a flask neck are ground-sealed, and the flask mouth is provided with a horn-shaped flaring. The flask mouth of the volumetric flask of the utility model is provided with the horn-shaped flaring bringing convenience for the volumetric flask to transfer a reference substance. When being transferred, the reference substance is not easy to scatter, thereby avoiding experimental errors. The volumetric flask of the utility model shortens the length of the flask neck, so reference substance solution in the volumetric flask can be convenient to be extracted, thereby preventing the leakage of the reference substance and ensuring the experimental precision. The short neck horn-shaped flaring volumetric flask has the advantages of simple structure and convenient use, and is particularly suitable for the volumetric flask with small volume to extract the reference substance solution.
Description
Technical field
The utility model relates to a kind of volumetric flask, relates in particular to a kind of short neck flare volumetric flask, belongs to the chemical analysis experiment instrument.
Background technology
Volumetric flask is the analyzing container commonly used that is used to prepare accurate volume and accurate concentration standard solution in the chemical experiment.Though the specification of volumetric flask is more, because its effect, determined its bottleneck, bottleneck thin more good more, this has brought very big trouble just for the preparation reference substance solution, reference substance is being transferred in the process of volumetric flask, because the capacity bottleneck is less, reference substance often occurs and be scattered in the outer situation of volumetric flask.The volumetric flask of special small size specification, because the bottleneck of this kind volumetric flask is not only thin but also long, very difficult during with the reference substance solution in the microsyringe absorption volumetric flask, the length of microsyringe front end pin is generally about 5cm, and the bottleneck of existing volumetric flask is often greater than 5cm, like this during the solution in drawing volumetric flask, often need volumetric flask is tilted to measure, be easy to cause the reference substance solution in the volumetric flask to leak like this, caused experimental error, also can affect to surrounding environment in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of reference substance that can make to be difficult for being scattered, and draws the short neck flare volumetric flask of solution in the bottle easily.
To achieve these goals, the technical solution of the utility model has adopted a kind of short neck flare volumetric flask, comprises bottle stopper, the bottleneck on the bottle, and ground sealing between the bottleneck of bottle stopper and bottleneck upper end, bottle mouth position has a flare.
The length of described bottleneck is less than 5cm.
The length of described bottleneck is 2-4cm.
The bottle mouth position of volumetric flask of the present utility model has a flare, and this just shifts reference substance to volumetric flask and has brought convenience, and during transfer, reference substance is difficult for being scattered, and has avoided experimental error.Volumetric flask of the present utility model has shortened the length of bottleneck, can draw reference substance solution easily from volumetric flask like this, has prevented leaking of reference substance, has guaranteed the accuracy of experiment.The utility model is simple in structure, and is easy to use, is specially adapted to the absorption of reference substance solution in the less volumetric flask of volume.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the bottle 6 of short neck flare volumetric flask of the present utility model is the flat vial of pyriform of a band bottleneck 5, bottleneck 3 is positioned at the upper end of bottleneck 5, ground sealing between the bottleneck 3 of bottle stopper 1 and bottleneck 5 upper ends, and there is a flare 2 at bottleneck 3 places.The length of the bottleneck 5 in the present embodiment is 3cm.
It should be noted last that: above embodiment is only in order to explanation, and unrestricted the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and not breaking away from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (3)
