熔封安瓿,通常系用煤气灯或酒精灯。但用酒精灯封口,价较贵,并且需用吹管,火焰不容易控制。而有煤气设备的地方,虽可用煤气喷灯,惟要得高温而尖锐的火焰,则必须用加压空气助燃(图1),以便安瓿能很快的熔封。但这样会发出噪音,令人厌烦。煤气喷灯有单头、变头及三头等类别。多数药厂均采用单头灯。因此熔封后的安瓿长短不齐,增加包装时整理的麻烦。 Fill ampoules, usually with gas or alcohol lamp. But sealed with alcohol lamp, the price is more expensive, and the need to use blowing, the flame is not easy to control. Where gas equipment is available, gas burners may be used. However, to obtain a high temperature and sharp flame, it must be supplemented with pressurized air (Figure 1) so that the ampoules can melt quickly. But it does make noise and it’s boring. Gas burner has a single head, head and head and other categories. Most pharmaceutical companies are using a single headlamp. Therefore, the length of the melted ampoules missing, increasing the packing finishing trouble.
