Abstract
The utility model discloses a beaker for chemical experiments, which comprises a beaker body and a thermometer, wherein a sanded edge is arranged at the mouth of the beaker body, and the thermometer is arranged on the inner wall of the beaker body. When in use, the mouth of the beaker body containing chemical substances is covered by a glass sheet, and the glass sheet covered at the mouth has fine sealing effect due to the sanded edge arranged at the mouth, thereby preventing the chemical substances volatilizing. When the chemical substances in the beaker body are used for chemical reaction, temperature in the beaker body can be measured by the thermometer in the beaker, thereby bringing convenience for operators to control reaction temperature and preventing the operating from being scalded. The beaker is reasonable in design, prevents the chemical substances volatilizing, increases operating safety in chemical experimental classes, and brings convenience to teaching of chemical teachers.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument, relates in particular to the beaker that a kind of chemical experiment is used.
Background technology
Last class hour of chemistry teacher, often need lead the experiment of student's instrumentation.Beaker all is a transparent vessel, and frequent conduct holds chemical substance or carries out the container of chemical reaction.Because beaker is open design, the volatile chemical that holds in beaker volatilization easily causes the thing amount to reduce.In addition, chemical reaction generally all can produce heat, and the reaction in the beaker sometimes is more violent, and it is more to produce heat, causes the beaker temperature very high, and the student is easy to when not knowing the beaker temperature remove to touch beaker with hand, scalds student's skin easily, influences experimental teaching.
Summary of the invention
Technical problem to be solved in the utility model is: the utility model provides a kind of chemical experiment beaker reliable, handling safety that uses, and this chemical test can prevent to evaporate with beaker, again can probe temperature.
For solving the problems of the technologies described above, the technical solution of the utility model is: the chemical experiment beaker, comprise cup, and the rim of a cup of described cup is provided with the frosted limit; Thermometer, described thermometer are arranged on the described cup inwall.
As a kind of improvement, described thermometer vertically is arranged on the described cup inwall.
As further improvement in the technical proposal, described rim of a cup is provided with a sharp mouth v notch v.
After having adopted technique scheme, the beneficial effects of the utility model are: because this chemical test comprises cup with beaker, the rim of a cup of described cup is provided with the frosted limit; Thermometer, described thermometer are arranged on the described cup inwall; So, when depositing chemical substance in the cup, cover on rim of a cup with a flat glass, because rim of a cup is provided with the frosted limit, make flat glass cover good sealing effect on rim of a cup, prevented the material volatilization; When the cup chemical substance is carried out chemical reaction, can record the temperature in the cup by the thermometer in the beaker, the handled easily person understands reaction temperature, avoids scalding.The utility model is reasonable in design, has prevented the volatilization of chemical substance, has improved the processing safety of chemical experimental courses again, has made things convenient for chemistry teacher's teaching.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structure cutaway view of the utility model embodiment;
Among the figure: 1, frosted limit; 2, thermometer sleeve; 3, thermometer; 4, breach; 5, graduation mark; 6, cup.
The specific embodiment
The chemical test beaker, as shown in drawings, comprise: cylindrical shape cup 6, the rim of a cup of described cup 6 is provided with a sharp mouth v notch v 4 of conveniently toppling over, and described rim of a cup end face is provided with frosted limit 1, is fixed with a thermometer sleeve 2 on the inwall of described cup 6, is fixed with a thermometer 3 in described thermometer sleeve 2, described thermometer 3 vertically is arranged on described cup 6 inwalls, and described thermometer 3 extends described cup 6 bottoms.Also be provided with graduation mark 5 on the back side of the utility model embodiment, conveniently read the volume amount of splendid attire solution.
The use principle of the utility model embodiment: in chemical experiment, the student gets certain solution with the beaker dress, before reacting, in order to prevent solution evaporation, can be at flat glass of the frosted limit of rim of a cup 1 loam cake, because the effect on frosted limit 1 makes sealing better, prevented that solution from wasting because of volatilization.When continuing test, when carrying out chemical reaction in cup 6, the student can be by the thermometer 3 good temperature conditions of measuring in the beaker, the heat that the reaction that has discharges is a lot, the student can read temperature in the beaker from thermometer 3, and the student is vigilant to scald thereby remind, and guarantees the experiment handling safety.
The utility model is reasonable in design, easy to use, handling safety is reliable, has guaranteed the efficient of chemical experiment teaching effectively.
