针对课本中气体的制备及性质实验装置复杂、气体易逸出等弊端,可结合教学实践设计一套用于气体制备及性质实验的装置——四足发生器。它构造简单,整个气体的发生及气体性质的检验都可以在这个密闭容器中进行,气体不易逸出,药品用量小,反应控制简单,尾气易于处理,轻巧且方便携带。多数的气体发生及气体性质的检验都可以在其中进行,使用范围较广。
According to the textbook gas preparation and nature of the experimental device is complex, the gas easy to escape and other shortcomings, can be combined with teaching practice to design a set of devices for gas preparation and properties of experiments - four-foot generator. The utility model has the advantages of simple structure, the occurrence of the whole gas and the test of the gas property can be carried out in the closed container, the gas is not easily escaped, the dosage of the drug is small, the reaction control is simple, the tail gas is easy to handle, the light is convenient and the portable is convenient. Most of the gas and gas properties of the test can be carried out in a wider range of use.
