介绍了一种新型酸式滴定管的结构、特点和使用方法.这种滴定管没有旋塞,使用操作方便;结构简单,造价低;滴定速度和滴定终点容易控制.消除了常规酸式滴定管旋塞处需涂凡士林,尖嘴处气泡难排出等缺陷.用数理统计方法,比较了研发的酸式滴定管和常规酸式滴定管的平行实验结果,发现使用新型滴定管进行滴定分析,其精度、准确度比50 mL的常规酸式滴定管稍高,其操作性远优于常规酸式滴定管.

The article describes the configuration, characteristics and usage of a new type of acid burette. This type of acid burette has not a faucet and easy to operation. It has simple structure, low costs, and the titration speed and the titration end point are easy to control. The defects of the conventional acid burette, such as daubing vaseline on the faucet being needed, eliminating bubbles from the bottom being difficult, are eliminated. The parallel determination results are compared with those obtained from the conventional acid burette by mathematical statistics methods. It shows that the new type of acid burette is superior in precision, accuracy compared with conventional 50 mL acid burette, and the operational performance is far more superior.
