在鉴定药物或做化学试验的时候,我们常会有这样的需要,根据反应中所产生的气体的化学性质来进行某种确证试验,或者是需要将某种气体通入反应液中后才能确证溶液中的某些含有物。为了达到这些目的,过去我们采用的方法是:用一个试管充当气体发生器,管口用装有弯曲导管的管塞塞好,气体产生后便经导管而通入另一含有液体的试管中(附图1),这种液体可能为试液(假如操作的目的是为了证实为 In the identification of drugs or chemical tests, we often have such needs, according to the chemical nature of the gas generated in the reaction to conduct a certain confirmation test, or need to pass a gas into the reaction solution to confirm the solution Some of them contain substances. In order to achieve these goals, the method we used in the past was to use a test tube as a gas generator. The nozzle was plugged with a pipe plug with a curved pipe. After the gas was generated, it was passed through a pipe to another test tube containing liquid ( Figure 1), this liquid may be a test solution (if the purpose of the operation is to confirm
