简易气体发生器装置(一): 取一段细玻璃管,用喷灯将其一端封死在距这端40毫米处喷用,灯加热,待玻璃红软用两手向中推间挤,使处红软堆起一圈凸形部分,其外径与具支U形管内径接近,以既漏不下小锌粒,又能透过稀盐酸为宜.然后按左图组装即可使用.不用时关闭活栓,氢气的压力使酸和锌粒脱离接触,反应立即停止. Simple gas generator device (1): Take a thin glass tube and close it with a blowtorch at 40 mm from this end. The lamp is heated until the glass is red and soft. Softly build up a circle of convex part, its outer diameter is similar to the inner diameter of the U-shaped tube with a branch, so as to not only leak small zinc particles, but also pass through dilute hydrochloric acid. Then it can be assembled according to the left figure. 3. The plug, the pressure of hydrogen gas released the acid and zinc particles and the reaction stopped immediately.
