Abstract
The utility model provides a volumetric flask with an expansion sealing mouth, which belongs to an experimental apparatus for teaching. The volumetric flask comprises a volumetric flask body, wherein the upper end part of the neck of the flask body is connected with a funnel flask mouth, and the upper part of the funnel flask mouth is connected with an expansion flask mouth; and the flask neck is connected with a sealing plug corresponding to the expansion flask mouth through a connecting rope. Compared with the prior art, the novel volumetric flask with the expansion sealing mouth has the characteristics of reasonable design, simple structure, convenience in use and the like, liquid can be conveniently taken out of the volumetric flask, the experimental efficiency is effectively improved, a solution can be prevented from being leaked, and the accuracy of experimental results is ensured.
Description
Technical field
The utility model relates to a kind of teaching laboratory apparatus, a kind of specifically volumetric flask with the expansion seal.
Background technology
At present in the chemistry teaching of school, often need do experiment and cooperate the student to understand, volumetric flask is the glass apparatus of the configuration standard solution used always in chemical laboratory.Volumetric flask is the flat bottle of a kind of thin neck pyriform, is made by colourless or brown glass, has ground glass stopper or plastic plug.In use, because the bottle stopper volume is little, the problem that bottle stopper is lost often takes place, because bottle and bottle stopper all pass through frosted, must closely cooperate just not can leakage, so after bottle stopper is lost or damaged, be difficult to find the bottle stopper that mates with bottle, the entire capacity bottle have to be scrapped.The specification of volumetric flask is more, and according to its effect, bottleneck is thin more good more, and this comparatively bothers with regard to making the solution of volumetric flask pour process into.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of band simple in structure, easy to use to expand the volumetric flask of seal.
The technical solution of the utility model realizes in the following manner, this a kind of volumetric flask with the expansion seal, its structure comprises the volumetric flask bottle, the bottleneck upper end of described bottle connects a funnel bottleneck, funnel bottleneck top is connected with the expansion bottleneck, is connected with by connection cord on the described bottleneck and expands the corresponding sealing-plug of bottleneck.
Described sealing-plug is fixed a cyclic sealing gasket with expansion contact site, bottleneck upper end.
Described connection cord is one to flexibly connect rope.
The beneficial effect that the utility model is compared with prior art produced is:
That a kind of volumetric flask with the expansion seal of the present utility model has is simple in structure, easy to use, characteristics such as be skillfully constructed, bottle stopper and bottle are connected as a single entity, the placement of convenient bottle stopper, avoid bottle stopper to lose, use is convenient, is provided with the expansion bottleneck, the convenient liquid of from volumetric flask, getting, effectively improve conventional efficient, prevent that solution from leaking, guarantee the accuracy of experimental result.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, bottle, 2, the funnel bottleneck, 3, the expansion bottleneck, 4, sealing-plug, 5, sealing gasket, 6, connection cord.
The specific embodiment
Below in conjunction with accompanying drawing a kind of volumetric flask with the expansion seal of the present utility model is done following detailed description the in detail.
As shown in Figure 1, this a kind of volumetric flask with the expansion seal, its structure comprises volumetric flask bottle 1, the bottleneck upper end of described bottle 1 connects a funnel bottleneck 2, funnel bottleneck 2 tops are connected with expansion bottleneck 3, are connected with by connection cord 6 on the described bottleneck and expand bottleneck 3 corresponding sealing-plugs 4.
Described sealing-plug 4 is fixed a cyclic sealing gasket 5 with expansion contact site, bottleneck 3 upper end, like this sealing-plug 4 with expand bottleneck 3 just can tight seal; Described connection cord 6 is one to flexibly connect rope, makes things convenient for the placement and the use of sealing-plug 4.
Claims (3)
- One kind with the expansion seal volumetric flask, comprise the volumetric flask bottle, the bottleneck upper end that it is characterized in that described bottle connects a funnel bottleneck, and funnel bottleneck top is connected with the expansion bottleneck, is connected with by connection cord on the described bottleneck and expands the corresponding sealing-plug of bottleneck.
- 2. according to claim 1 a kind of with the expansion seal volumetric flask, it is characterized in that described sealing-plug with the expansion contact site, bottleneck upper end fix a cyclic sealing gasket.
