Description

Novel volumetric flask

Technical field

The application belongs to experimental article field, specifically, relates to a kind of Novel 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 of the solution for preparing certain substance withdrawl syndrome accurately.The bottleneck of general volumetric flask is more elongated, if liquid level of solution reduces in bottle, then may get less than liquid not because of the length of micropipettor, meanwhile, when carrying out a large amount of outward-dipping transfer of solution in bottle, can make to produce a large amount of bubbles in bottle, affect solution outwards to shift, solution even can be made excessive in a large number, cause solution to lose in a large number, in addition, due to the shape of volumetric flask, in moving process, body is easy to topple over, and causes solution in bottle excessive, causes unnecessary loss.Experiment terminates, and generally can only insert hairbrush cleaning, because the reason hairbrush of body cannot clean from bottleneck.

Utility model content

In view of this, technical problems to be solved in this application body in moving process is easy to topple over, and causes the technical problem that solution in bottle is excessive.

In order to solve the problems of the technologies described above, this application discloses a kind of Novel volumetric flask, comprise bottleneck, bottle stopper and body, described bottleneck upper end is provided with bottleneck, between described bottle stopper and described bottleneck, ground seals, described bottleneck lower end is communicated with described body, and described body lower end is provided with opening, and described opening is connected with U-shaped glass tube.

Further, described U-shaped glass tube and described body contour.

Further, described U-shaped glass tube top is provided with pipe close.

Further, the material of described bottle stopper and described pipe close is polytetrafluoroethylene (PTFE).

Further, the internal diameter 12-14mm of described bottleneck.

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

Compared with prior art, the application can obtain and comprise following technique effect: a kind of Novel volumetric flask of the application, structure is simple, easy to operate.By add at the body lower ending opening place of volumetric flask contour with circular body, with bottleneck with the U-shaped glass tube of internal diameter, open bottle stopper during use, have the following advantages:

1, micropipettor can be facilitated from U-shaped glass tube directly to enter the liquid drawn in volumetric flask.

2, solution transfer in volumetric flask is convenient to.

3, volumetric flask bottom-purge is convenient to.

In addition, add at the body lower ending opening place of volumetric flask contour with circular body, with bottleneck with the U-shaped glass tube of internal diameter, can prevent volumetric flask from toppling over.

Certainly, the arbitrary product implementing the application must not necessarily need to reach above-described all technique effects simultaneously.

Accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present application, and form a application's part, the schematic description and description of the application, for explaining the application, does not form the improper restriction to the application.In the accompanying drawings:

Fig. 1 is the structural representation of the application's Novel volumetric flask.

Detailed description of the invention

Drawings and Examples will be coordinated below to describe the embodiment of the application in detail, by this to the application how application technology means solve technical problem and the implementation procedure reaching technology effect can fully understand and implement according to this.

This application provides a kind of Novel volumetric flask, as shown in Figure 1, comprise bottleneck 2, bottle stopper 1 and body 3, described bottleneck upper end is provided with bottleneck, and between described bottle stopper 1 and described bottleneck, ground seals, described bottleneck 2 lower end is communicated with described body 3, described body 3 lower end is provided with opening 31, and described opening is connected with U-shaped glass tube 32, and described U-shaped glass tube 32 is contour with described body 3, described U-shaped glass tube 32 top is provided with pipe close 33, and the material of described bottle stopper 1 and described pipe close 33 is polytetrafluoroethylene (PTFE).

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

Concrete use is, when volumetric flask under normal usage, bottle stopper 33 is placed on U-shaped glass tube 32, prevents solution from outwards overflowing.When needs outwards topple over that in volumetric flask, solution is in reagent bottle, inclination volumetric flask, makes U-shaped glass tube 32 bottleneck upwards, opens bottle stopper 33, open volumetric flask bottle stopper 1, carries out solution in volumetric flask and outwards shifts; At the end of outwards toppling over, cover bottle stopper 33, cover volumetric flask bottle stopper 1.When experiment needs to draw solution in volumetric flask, now in volumetric flask, solution is positioned at volumetric flask bottleneck less than 2, bottle stopper 33 can be taken off, and micropipettor directly draws the solution in volumetric flask by U-shaped glass tube 32.At the end of experiment, also bottle stopper 33 can be taken off, hairbrush is by the bottom of the direct washer bottle of U-shaped glass tube 32.

A kind of Novel volumetric flask of the application, structure is simple, easy to operate.By add at body 3 lower ending opening 31 place of described Novel volumetric flask contour with circular body 3, with bottleneck 2 with the U-shaped glass tube 32 of internal diameter, open bottle stopper 1 during use, have the following advantages:

1, micropipettor can be facilitated from U-shaped glass tube 32 directly to enter the liquid drawn in volumetric flask.

2, solution transfer in volumetric flask is convenient to.

3, volumetric flask bottom-purge is convenient to.

In addition, add at body 3 lower ending opening 31 place of volumetric flask contour with circular body 3, with bottleneck 2 with the U-shaped glass tube 32 of internal diameter, can prevent volumetric flask from toppling over.
