我们设计并制作一种气体和检验合为一体的反应槽,凡是液一液,液一固药品反应,不需加热而产生气体,如等,均可用此槽演示.反应槽的外形如图一所示,左一槽为发气槽,其它为验气槽. We design and fabricate a reaction tank in which gas and inspection are integrated into one body. Any liquid or liquid that reacts with a solid chemical does not require heating to generate gas. For example, we can use this tank for demonstration. The appearance of the reaction tank is shown in Figure 1. As shown, the left trough is the air trough and the others are the trachea trough.
