德国Merck默克Volumetric solution 当量标准溶液

易于操作,方便使用重视实验室储存及使用安全:只有Titrisol同时具有危险警告标记。危险警告说明及包装和每个安瓿管上的Risk & Safely指示浓度符合DIN标(DIN32625)–准确的浓度意味着可靠的结果配合数显温度计检测环境温度:确保滴定精确长有效期保证了长期的可靠性节省空间;可直接储放在工作台上可灵活改变其原有浓度:通过变化zui终体积或Titrisol安瓿管数量可制备相应的浓度可灵活选择溶剂;Titrisol安瓿管加上一个合适的溶剂可制备无水当量溶液缓冲溶液更加方便使用:所有的Titrisol缓冲液都标有相应温度(0-90℃)对应的PH值及缓冲液的成份滴定是实验室zui常见的化学成分分析方法,滴定不同组分通常需要相应的当量溶液,而制备标定这些当量溶液的过程既费时又费力。如今, MERCK推出已配制好的高品质当量溶液,滴定度偏差小于1.000±0.1%,而且批与批之间参数稳定。共有62种品种,包装从100毫升到25毫升不等。
