摘要
介绍一种新型滴定管。该滴定管的特点主要体现在液流控制阀上，它采用模注塑部件装配而成，改变了传统滴定管的构造及操作方式，具有耐酸碱、耐氧化还原的能力，实现酸、碱滴定管合二为一，提高滴定管的操作性能，且造价低廉，具有推广应用价值。
Introduction of a new type of titration tube is presented.The feature of this titration tube is chiefly embodied in fluid control valve,which is assembled with parts of injection mould from model,and it has changed the structure and operation of the traditional titration tube;and it can resist acid,alkali and reduction of oxidation.It also makes acid and alkali titration tubes one and has improved the operational function of titration tube.The cost of tubemaking is very low and it’s certainly valuable in practice.
