If the gas needs to be purified or dried in the gas making process, more instruments are involved, the operation is inconvenient, the integration is difficult, and the assembly takes time.
2. In the gas property experiment, the reaction gas needs to be prepared and collected in advance for the experiment, but the gas preparation device is difficult to prepare the gas temporarily, so that the teaching preparation time is easy to be too long, the gas collected in advance is easy to escape, and finally the effect of the gas property experiment is influenced.
3. The temporary addition of the medicine is inconvenient, the waste liquid treatment and the recovery of the solid medicine are inconvenient, and the device is not easy to clean and the like.
In addition, in the experimental apparatus shown in fig. 1 and fig. 2, the liquid is directly added into the reaction vessel through the long-neck funnel, and the solid and the liquid after the reaction can not be separated, and the reaction can not be controlled to be started and stopped at any time. The experimental device shown in the attached figure 3 has the defects of complex instrument, high price, uncontrollable reaction which is easy to fall into the bottom of the container and is started and stopped at the same time, and the like. The experimental device shown in the attached figure 4 has the defects that the manufacturing of the porous partition plate is difficult, the solid is easy to fall into the bottom of the test tube, the reaction cannot be controlled and is started and stopped at any time, and the like.
In order to overcome the disadvantages of the gas preparation device, a gas experimental device which can integrate preparation and property experiment needs to be provided.
