摘要
在实验室之中,通过对玻璃量器进行计量检定操作,能够将其准确性特点展示出来,为后续实验数据的准确获取创造更多条件。文章根据以往工作经验,对影响实验室玻璃量器准确度的因素进行总结,并从滴定管的使用方法、吸量管的使用方法、容量瓶的使用、量筒及量杯的使用四方面,论述了实验室玻璃量器准确度的具体把握方法。
In the laboratory,through the metrological verification operation of the glass measuring device,the accuracy characteristics can be displayed,creating more conditions for the accurate acquisition of subsequent experimental data.Based on past work experience,this paper summarizes the factors affecting the accuracy of laboratory glass gauges,and discusses the experiments from the use of burettes,the use of pipettes,the use of volumetric flasks and the use of measuring cylinders and measuring cups.Finally,it specifies the method of grasping the accuracy of the room glass measuring device.
