常用玻璃量器包括单标线容量瓶、单标线吸管、分度吸管、滴定管、量筒、量杯是医院、药厂、药检所工作必须用的量器,使用率较高,由于有一些试剂如酸碱等对玻璃量器的影响,及洗刷中的磨损等原因,实际容积并不一定与标示值完全一致,即刻度不一定十分准确,从而引入误差,使检测数据不准确,不可靠。因此玻璃量器应定期检定,使之处于允许误差范围之内。 根据“中华人民共和国计量法”第二十二条的规定,“为社会提供公证数据的产品质量检验机构,必须经省级以上人民政府计量行政部门对其检定、测试能
Commonly used glass volumetric gauges include single standard line volumetric flask, single standard line pipette, indexing pipette, burette, graduated cylinder and measuring cup. It is a measuring device that must be used in hospitals, pharmaceutical factories and drug testing institutes. Due to the high usage rate, Acid and alkali on the impact of glassware, and scrubbing and other reasons, the actual volume is not necessarily exactly the same with the indicated value, the scale is not necessarily very accurate, so the introduction of error, the test data inaccurate, not reliable. Therefore, the glass should be regularly checked, so that it falls within the allowable error range. According to Article 22 of the “Metrology Law of the People’s Republic of China”, "a product quality inspection agency that provides notary data to the public must pass the examination and test of the administrative department of measurement under the people’s government at or above the provincial level
