化学实验中需要排水集气的地方很多，用传统的方法集气，收集满一瓶气体就得盖上玻片从水中拿出来，然后再收集下一瓶。在这期间就有一部分气体外选，造成药品的浪费，如果是有害气体还会造成空气污染。为解决这一问题，我自制了一种集气盘。观介绍如下：集气盘是用有机玻璃粘 In chemical experiments, there are many places where drainage and gas gathering are required. Gas is collected in the traditional way. To collect a full bottle of gas, it is necessary to cover the glass with water and then collect the next bottle. During this period, a portion of the gas was selected, resulting in the waste of medicines. If it is a harmful gas, it will also cause air pollution. In order to solve this problem, I made a kind of gas gathering plate. Views are as follows: The gas pan is made of organic glass.
