目的分析理化检验中可调移液器的应用价值。方法通过将可调移液器移取蒸馏水的质量和同温度水的标准密度计算真实体积并进行校准,比较可调移液器和玻璃刻度吸管在精确加液方面的差别。结果可调移液器准确性较高,所产生的误差较小。与玻璃刻度吸管比较,具有较高的准确性和精密度。结论在理化检验工作中,可调移液器具有较高的使用价值。
Objective To analyze the application value of adjustable pipette in physical and chemical test. Methods The real volume was calculated and calibrated by comparing the mass of pipette transferred to distilled water with the standard density of water at the same temperature to compare the difference between the precise pipetting of the adjustable pipette and glass graduated pipette. The result is a more accurate pipette with less error. Compared with the glass graduated pipette, with high accuracy and precision. Conclusion In the physical and chemical testing, adjustable pipette has a high value.
