Description
Technical field
This utility model relates to the crucible that the detection of a kind of chemical field uses, and particularly relates to a kind of politef crucible.
Background technology
At present, polytetrafluoroethylene (PTFE) crucible is widely used in the industries such as chemical industry, oil, environmental protection, scientific research, its decay resistance of the container that politef is made is fine, so being widely used again in the middle of chemical detection experiment, the superiority of politef crucible is favored by users, inner wall smooth, use temperature 200 DEG C��+250 DEG C, on electric hot plate, short-term is resistant to 300 DEG C, for the evaporation of solution, concentration or crystallization, calcination solid matter, clears up sample, catches up with acid, boils, is evaporated etc. and to process. But existing politef crucible crucible body is cylinder, lid is bottom is plane, organic substance in crucible body is liable to stick on crucible internal walls in an experiment, and when observing sample when needing in experiment to uncap, some liquid being attached to lid bottom easily run off, and affect experimental data.
Summary of the invention
In view of this, it is necessary to overcome at least one in drawbacks described above of the prior art, the utility model proposes a kind of politef crucible.
Described politef crucible, including crucible cover, crucible body, described crucible body is cone, downwardly convex bottom described crucible cover.
According in this patent background technology to described in prior art, currently used politef crucible, crucible body is cylinder, crucible cover bottom is plane, organic substance in crucible body is liable to stick on crucible internal walls in an experiment, when observing sample when needing in experiment to uncap, some liquid being attached to lid bottom easily run off, and affect experimental data; And the disclosed a kind of politef crucible of this utility model, owing to crucible structural reform is cone, when within crucible evaporate out after, major part liquid is attached to wall surface in crucible body, the organic substance of surface attachment in crucible body can constantly be rinsed backflow by the acid simultaneously volatilized, crucible cover lower end is protruding, condense in the liquid on crucible cover to condense in convex surfaces and be slipped to portion in crucible body, so that medicine makes full use of in experiment, thus contributing to the accuracy of experimental data, therefore this utility model has clear advantage.
It addition, politef crucible also has following supplementary features disclosed in this utility model:
Further, described crucible body upper end open diameter is less than described crucible body base diameter further, described crucible cover and described crucible body match, and described crucible cover upper end diameter is more than lower end diameter, it is simple to interior liquid material is built up after condensing and flows back in described crucible body.
Further, there is a handle above described crucible cover, it is simple to uncap.
A kind of politef crucible that this utility model provides, it is not only simple in structure, reasonable in design, and in testing crucible body described in taper be easy to volatilization acid rinse and be attached in described crucible body the organic matter on surface in a large number, and downwardly convex crucible cover be easy to interior liquid material condense after build up and flow back in described crucible body, reduce observe sample uncap time lid bottom liquid flow out and affect experimental data.
The additional aspect of this utility model embodiment and advantage will part provide in the following description, and part will become apparent from the description below, or is recognized by practice of the present utility model.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present utility model and advantage are from conjunction with will be apparent from easy to understand the accompanying drawings below description to embodiment, wherein:
Fig. 1 shows this utility model one politef crucible schematic diagram;
Fig. 2 shows the crucible cover front schematic view in this utility model;
In Fig. 1,1 crucible cover, 2 crucible bodies, 101 handles;
In Fig. 2,102 is protruding.
Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish. The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining this utility model, and can not be construed to restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " on ", D score, " end ", " top ", "front", "rear", " interior ", " outward ", " horizontal stroke ", the orientation of the instruction such as " erecting " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
In description of the present utility model, it is necessary to explanation, unless otherwise clearly defined and limited, term " connection ", " connection ", " being connected ", " connection ", " cooperation " should be interpreted broadly, for instance, it is possible to it is fixing connection, connect integratedly, it is also possible to be removably connect; It can be the connection of two element internals; Can be joined directly together, it is also possible to be indirectly connected to by intermediary; " cooperation " can be face and the coordinating of face, it is also possible to is point and the coordinating of face or line and face, also includes the cooperation of hole axle, for the ordinary skill in the art, it is possible to concrete condition understanding above-mentioned term concrete meaning in this utility model.
A kind of politef crucible as shown in Figure 1, including crucible cover 1, crucible body 2, described crucible body 2 is cone, bottom described crucible cover 1 downwardly convex 102.
According in this patent background technology to described in prior art, currently used politef crucible, crucible body is cylinder, crucible cover bottom is plane, organic substance in crucible body is liable to stick in crucible body on wall in an experiment, when observing sample when needing in experiment to uncap, some liquid being attached to lid bottom easily run off, and affect experimental data; And the disclosed a kind of politef crucible of this utility model, including crucible cover 1, crucible body 2, described crucible body 2 is cone, bottom described crucible cover 1 downwardly convex 102, when organic substance is attached on described crucible body 2 inwall, the acids of the volatilization in experiment is agglomerated to crucible body 2 inwall and protruding 102 surfaces of crucible cover 1 reach certain gravity and flow back to bottom crucible body 2, so that medicine makes full use of in experiment, thus contributing to the accuracy of experimental data, therefore this utility model has clear advantage.
