23、品固定器从试验器皿中移出来，水洗干净。硝酸可将之储存在试验器皿上。如果蒸气在试验容器变成褐色或红褐色，需要将盖子打开，让深色汽从试验器皿散出。当试验区变得清晰些的时候再将盖子盖上。需要注意的是，要将盖子关闭三十分钟后，才可开始一项新的实验。太热的试验溶液，将使汽体变色。每两个星期做的试验，是将溶液倒入有刻度的500毫升的玻璃瓶中。检查硝酸的容量，若需要要加至500毫升，酸的密度必须使用密度比重计进行检查。每3个月，试验用的溶液必须更换。硝酸废物的处理，必须按照当地的法律指示执行。当样品落入酸里时，试验用的溶液必须更换。精心整理如果酸溶液里能够看到气体变色，试验用的溶液必须更换ProcessSa
