摘要
介绍了一种新型滴定管的结构、特点及使用方法 ,通过数理统计对新型滴定管与经典滴定管平行测定结果进行了比较。新型滴定管具有较好的精密度、准确度和操作性能 ,克服了经典滴定管活塞易渗漏、易产生气泡、装液困难、近终点液滴不易控制及酸碱不通用的缺点。
The configuration characteristics and operation of a new buret was described. The parallel determination results was compared with those obtained from the conventional buret by mathematical statistics methods. It shows that the new buret is superior in precision ,accuracy and operational performance . The new buret has many distinguishing features, such as no leakage, no bubbles, automatic filling, automatic zero set.In addition , it is easy to be operated, easy to grasp the titration end point and can be applied widely.
