Abstract
The utility model discloses a chemical reaction gas volume measuring device which comprises a gas generator and a liquid storage bottle, wherein the gas generator is fixed on the liquid storage bottle, the original rubber plug at the lateral feed port of the gas generator is changed into a graduated glass syringe made from a glass branch pipe provided with a ground piston, a temperature meter is inserted into the mouth of the liquid storage bottle through a cork plug, and the original rubber plug at the main opening of the gas generator is changed into a movable graduated glass syringe provided with a ground piston. By adopting the technical scheme, the chemical reaction gas volume measuring device solves the easy leakage problem, and has small error and high success rate compared with the conventional experimental instruments.
Description
Technical field
The utility model relates to a kind of instruments used for education, and what be specifically related to is chemical reaction gas stereometry device.
Background technology
At present, along with the development of educational undertaking, encourage to cultivate the talent, but under the background of education now, many teaching equipments can not be synchronous with the classroom, the progress of influence teaching with manipulative ability.Because chemical reaction gas stereometry instrument apparatus design improper (going up version chemistry first term of the Senior Two P48 Figure 10-1 of section), the volume of measuring 1mol gas is whenever once tested syringe needle will prick into the charge door rubber stopper three times, and be to reduce experimental error test will carry out three such tests, finish the test battery syringe needle like this and will prick into the charge door rubber stopper nine times.The charge door rubber stopper time is once long cracking easily.Because above-mentioned reason, it is high even can not read the volume that liquid data can't convert hydrogen to usually will to produce very large experimental error, success ratio.For keeping the good characteristics of its stationarity, mainly charge door and bleeding point are improved reducing the operation steps and the error of " difficulty of bleeding " at ordinary times, and the device that solves the siphonage problem is not in the lump also being sold on the market.
The utility model content
The utility model provides a kind of chemical reaction gas stereometry device according to above-mentioned deficiency.
For achieving the above object, the technical solution of the utility model is a chemical reaction gas stereometry device, form by gas generator and liquid storage bottle, wherein gas generator is fixed on the liquid storage bottle, and the side loading mouth of described gas generator rubber plug originally makes the graduated glass syringe that glass props up pipe racks ground piston into.
The bottleneck of described liquid storage bottle is plugged thermometer with cork.
The trunk opening of described gas generator rubber plug originally makes the graduated glass syringe of mobilizable band ground piston into.The beneficial effect of technique scheme is: 1, device simple fixation, and design meets principle on the textbook, and simplified control is convenient.
2, the data in the experiment intuitively show the precision height.
3, solved easy gas leakage problem, compared to former experimental apparatus error little success ratio height very.
4, can very easily demonstrate experimental principle to students by improved instrument and watch, help the student to learn to understand, reach teaching purpose.
Description of drawings
Fig. 1 is the utility model one-piece construction synoptic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.By shown in Figure 1, a kind of chemical reaction gas stereometry of the utility model device, form by gas generator and liquid storage bottle, wherein gas generator is fixed on the liquid storage bottle, and the side loading mouth of described gas generator 6 rubber plug originally makes the graduated glass syringe 7 that glass props up pipe racks ground piston into; The bottleneck of described liquid storage bottle is plugged thermometer 2 with cork; The trunk opening of described gas generator 6 rubber plug originally makes the graduated glass syringe 1 of mobilizable band ground piston into; Gas receiving flask 3 is connected on the liquid storage bottle by conduit, is mounted with thermometer 2 on the liquid storage bottle, and thermometer 2 is placed on the liquid level of liquid storage bottle the inside below 5, and liquid storage bottle, gas receiving flask and gas generator are placed on groove 4 the insides.
