Abstract
The utility model provides a three-necked round-bottom flask. The flask comprises a flask body, wherein three flask mouths are formed in the upper portion of the flask body. The three flask mouths are respectively an ordinary flask mouth, a graduated cylinder flask mouth and a distillation flask mouth. Sealing stoppers are all arranged on the ordinary flask mouth, the graduated cylinder flask mouth and the distillation flask mouth. Compared with the prior art, the three-necked round-bottom flask has the advantages of being rational in design, simple in structure and convenient to use and the like. Integrating the ordinary flask and the distillation flask, the three-necked round-bottom flask is capable of auto-completing measurement when liquid is poured into the flask. The three-necked round-bottom flask has multiple functions and good use value.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument, specifically a kind of three mouthfuls of simple in structure, multiple functional round-bottomed flasks.
Background technology
In chemical experiment teaching, round-bottomed flask is one of the instrument that often will use.The round-bottomed flask mouth of prior art is thinner, can prevent that liquid from flowing out, and can carry out long-time heating, but necessary pinner web, can the large quantity of fluid of airtight heating.Existing round-bottomed flask is divided into two kinds of common flask and distilling flasks, liquid in the flask needs to insert after complete with other instrument amount first again, the teacher need to come which kind of flask of choice for use according to experiment purpose in the experimentation, will increase like this complexity of experiment, reduces teacher's conventional efficient.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, three mouthfuls of round-bottomed flasks are provided.
The technical solution of the utility model realizes in the following manner, these a kind of three mouthfuls of round-bottomed flasks, its structure comprises bottle, described bottle top is provided with three bottlenecks, these three bottlenecks are respectively common bottleneck, graduated cylinder bottleneck, distillation bottleneck, are provided with sealing bottle cork at common bottleneck, graduated cylinder bottleneck, distillation bottleneck.
As preferably, described graduated cylinder bottleneck refers to that this bottleneck is the graduated cylinder shape, and its bottom is connected with bottle by control valve.Adopt the bottleneck of this structure, can be so that the liquid volume in the flask be controlled, convenient carrying out smoothly of testing.
As improvement, the distillation tubule is set on the sidewall of described distillation bottleneck.Adopt this technical scheme common flask and distilling flask can be combined, one-object-many-purposes, practical function expansion.
The beneficial effect that the utility model compared with prior art produces is:
The characteristics such as that a kind of three mouthfuls of round-bottomed flasks of the present utility model have is simple in structure, easy to use, be skillfully constructed, the utility model integrates common flask, distilling flask, can automatically finish measurement when pouring liquid into, multiple functional, use procedure is flexible, the Effective Raise conventional efficient improves teacher's quality of instruction and speed, thereby the utlity model has good use value.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing represents respectively:
1, bottle, 2, common bottleneck, 3, sealing bottle cork, 4, the graduated cylinder bottleneck, 5, control valve, 6, the distillation bottleneck, 7, the distillation tubule.
The specific embodiment
Below in conjunction with accompanying drawing a kind of three mouthfuls of round-bottomed flasks of the present utility model are described in detail below.
As shown in Figure 1, these a kind of three mouthfuls of round-bottomed flasks, its structure comprises bottle 1, described bottle 1 top is provided with three bottlenecks, these three bottlenecks are respectively common bottleneck 2, graduated cylinder bottleneck 4, distillation bottleneck 6, are provided with sealing bottle cork 3 at common bottleneck 2, graduated cylinder bottleneck 4, distillation bottleneck 6.
Described graduated cylinder bottleneck 4 refers to that this bottleneck is the graduated cylinder shape, and its bottom is connected with bottle 1 by control valve 5.Distillation tubule 7 is set on the sidewall of described distillation bottleneck 6.
