《中学化学教学参考》1976年第一期曾介绍了一种清洗滴定管尖头的简便方法。诚然,运用这种方法确能达到清洗滴定管尖头的目的,但用此方法清除尖头堵塞物时,所用铜丝不能太粗太硬,需要使用24号铜丝。而这种规格的铜丝,往往不能随手即得;同时,在穿拉铜丝时动作要轻,否则关头管口亦易受损坏,而使滴定管报废。因此,该法虽然可用,但并不是唯一简便的方法。
A reference to the chemistry teaching in middle schools in the first phase of 1976 introduced a simple method for cleaning the tip of a buret. Of course, using this method can really achieve the purpose of cleaning the tip of the buret, but when using this method to clear the tip of the plug, the copper wire used can not be too thick and hard, need to use 24 copper wire. This type of copper wire is often not readily available; at the same time, the action must be light when the copper wire is pulled in, otherwise the juncture nozzle is also susceptible to damage and the burette is scrapped. Therefore, although this law is available, it is not the only convenient method.
