玻璃量器在化学实验中使用频繁,因此它的性质、正确使用、精度直接影响化学实验数据的准确性。由于厂家设备、计量方法等因素使玻璃量器容易产生不同的系统性偏差,而玻璃量器的整个使用过程均是手工操作,稍有不慎就会影响到实验的测量结果。本文主要通过几种常见的玻璃量器的使用来分析一下影响误差的因素及消除方法。 Glassware is used frequently in chemical experiments, so its properties are used correctly and its accuracy directly affects the accuracy of chemical experimental data. Due to the equipment of the factory, the measurement method and other factors, the glass doser tends to have different systematic deviations. However, the whole process of using the glass doser is manual and the slightest mistake will affect the experimental measurement results. This article mainly through the use of several common glass to analyze the factors that affect the error and eliminate methods.
