Abstract

The application discloses volumetric flask, including bottleneck, bottle plug and body, the bottleneck upper end is equipped with the bottleneck, the bottle plug with the ground is sealed between the bottleneck, the bottleneck lower extreme with the body intercommunication, bottleneck department is equipped with the flaring. The application provides a volumetric flask, in the time of can preventing effectively that bottle interior solution from outwards pouring the reagent bottle into, because the volumetric flask neck is longer and thinner, and the solution that leads to loss. This application simple structure, convenient operation, the great volumetric flask of specially adapted volume.

Description

Volumetric flask

Technical field

The application belongs to experimental article field, specifically, relates to a kind of volumetric flask.

Background technology

Volumetric flask is a kind of thin flat bottle of neck pyriform, is made up of colourless or brown glass, with ground glass stopper or plastic plug, is the fine instrument for the preparation solution of certain substance withdrawl syndrome accurately.

Volumetric flask is a kind of thin flat bottle of neck pyriform with ground glass stopper or plastic plug, is specifically used to the Accurate Analysis chemical experimental instrument of preparation certain volume, certain substance withdrawl syndrome solution. Volumetric flask is measuring device, is not container, avoids standard solution and deposits in volumetric flask, should outwards be poured into by the solution prepared in reagent bottle and preserve in bottle.

Existing capacity bottleneck is more elongated, and when in bottle, solution outwards shifts, solution has a small amount of spilling, causes solution loss.

Utility model content

In view of this, the application to solve owing to capacity bottleneck is more elongated, and when in bottle, solution outwards shifts, solution has a small amount of spilling, causes the technical problem of solution loss.

In order to solve above-mentioned technical problem, this application discloses a kind of volumetric flask, including bottleneck, bottle stopper and body, described bottleneck upper end is provided with bottleneck, between described bottle stopper and described bottleneck, ground seals, and described bottleneck lower end connects with described body, and described bottle mouth position is provided with enlarging.

Further, described enlarging is provided with beaker mouth.

Further, described enlarging be shaped as tubaeform.

Further, it is provided with the first opening in the middle part of described bottleneck.

Further, it is provided with the second opening in the middle part of described body.

Further, it is connected to hollow handle between described first opening and the second opening.

Further, the internal diameter of described hollow handle is identical with the internal diameter of described bottleneck.

Further, the inside diameter ranges of described bottleneck is 12-14mm.

Further, the length of described bottleneck is not less than 50mm.

Compared with prior art, the application can obtain and include techniques below effect: the volumetric flask that the application provides, it is possible to when being effectively prevented that in bottle, solution outwards pours reagent bottle into, owing to capacity bottleneck is more elongated, and the solution loss caused. The application simple in construction, easy to operate, it is particularly well-suited to the volumetric flask that volume is bigger.

Certainly, the arbitrary product implementing the application must be not necessarily required to reach all the above technique effect simultaneously.

Accompanying drawing explanation

Accompanying drawing described herein is used for providing further understanding of the present application, constitutes the part of the application, and the schematic description and description of the application is used for explaining the application, is not intended that the improper restriction to the application.In the accompanying drawings:

Fig. 1 is the structural representation of a kind of volumetric flask of the application;

Fig. 2 is the top view of a kind of volumetric flask of the application.

Detailed description of the invention

Describe presently filed embodiment in detail below in conjunction with drawings and Examples, thereby the application how application technology means are solved technical problem and reaches the process that realizes of technology effect and can fully understand and implement according to this.

The application one volumetric flask, as shown in Figures 1 and 2, including bottleneck 2, bottle stopper 4 and body 3, described bottleneck 2 upper end is provided with bottleneck, between described bottle stopper 4 and described bottleneck, ground seals, described bottleneck 2 lower end connects with described body 3, described bottle mouth position is provided with enlarging 5, described enlarging 5 is provided with beaker mouth 1, being shaped as of described enlarging 5 is tubaeform, the first opening 6 it is provided with in the middle part of described bottleneck 2, the second opening 8 it is provided with in the middle part of described body 3, it is connected to hollow handle 7 between described first opening 6 and the second opening 8, the internal diameter of described hollow handle 7 is identical with the internal diameter of described bottleneck 2.

In the present embodiment, the internal diameter of described bottleneck 2 is 13mm, and the length of described bottleneck 2 is 50mm.

Time specifically used, when needing the solution prepared in by volumetric flask outwards to pour reagent bottle into, opening bottle stopper 4, hold empty-handed handle 7, tilt volumetric flask, solution is injected in reagent bottle along beaker mouth 1, carries out solution and outwards shifts; When pouring out end, cover bottle stopper 4. Whole process is just as toppling over boiled water from thermos flask.

This application provides a kind of volumetric flask, it is possible to when being effectively prevented that in bottle, solution outwards pours reagent bottle into, owing to capacity bottleneck is more elongated, and the solution loss caused. The application simple in construction, easy to operate, it is particularly well-suited to the volumetric flask that volume is bigger.

It can further be stated that, term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include the commodity of a series of key element or system not only includes those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this commodity or system. When there is no more restriction, statement " including ... " key element limited, it is not excluded that there is also other identical element in the commodity including described key element or system.

Described above illustrate and describes some preferred embodiments of the application, but as previously mentioned, it is to be understood that the application is not limited to form disclosed herein, it is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and environment, and in application contemplated scope described herein, can be modified by the technology of above-mentioned instruction or association area or knowledge. And the change that those skilled in the art carry out and change are without departing from spirit and scope, then all should in the protection domain of the application claims.
