100 mL单标线吸管不确定度评定

Evaluation of Uncertainty of 100 mL Singlet Straw

常用玻璃量器是一种广泛运用于检验检测、医疗卫生、环境监测等各类化学分析实验室的容量计量器具,其容量值由于受测量中各种因素的影响,其测量结果存在不确定性,本文以单标线吸管容量测量结果不确定的评定为例,对常用玻璃量器影响测量结果的不确定因数进行辨识,为实验室提供常用玻璃量器校准和不确定度评定的方法参考。

Working glass container is a kind of capacity measuring instruments that can be widely used in various chemical analysis laboratories in the field of inspection and testing, medical and health, environmental monitoring. The uncertainty of the capacity value of the working glass container exists owning to various factors in the measuring process. In this paper,taking the measurement uncertainty of the one-mark pipette capacity measurement as an example,the calibration and uncertainty of the working glass container to the laboratory have been identified and provided.
