我們制作了三种气体发生器,详见附图。所需材料少,制作簡便,使用方便,現簡述如下: 第一种:用噴灯把U形管一边的中下部逐漸加热烧紅,用圆头镊子在其周围按几个坑(五、六个即可,不能打穿),这样管内玻璃的突出部分正好可把所加入的金属块架住。再配上紧密的皮塞和导管便可使用。第二种:在一长約12—15厘米,直径此錐形瓶口略小的玻璃管或破試管的下半截,如上述一样烧紅按上小坑。装上严紧的胶塞和导管,放入錐形瓶中即可。
We made three gas generators, as shown in the attached drawings. Less materials, easy production, easy to use, are summarized as follows: The first: U-shaped tube with a torch to the lower and middle heating gradually red, with round tweezers in its periphery by a few pit (five, Six can, can not be punctured), so that the protruding part of the glass tube is just enough to put the added metal block shelf. Coupled with the tight plug and catheter can be used. The second: In a length of about 12-15 cm, the diameter of this tapered bottle slightly smaller glass tube or broken tube half of the lower half, as above red hot press the pit. Install tight rubber stopper and catheter, into the conical flask can be.
