容量瓶温变试验及其应用

TEST OF THE VARIATION FOR THE VOLUMETRIC FLASK CAPACITY ACCORDING TO THE TEMPERATURE

试验了容量瓶经升温、降温后容量的变化。试验表明,容量瓶具有良好的热恢复性,用容量瓶直接配制溶液对溶液浓度影响不大。

The test on the variation of the volumetric flask capacity according to the temperature was made.It was shown that the capacity changed hardly when the temperature failed to room temperature after the volumetric flask had been heated,and the solution concentration was hardly effected when the solution was directly compounded in the volumetric flask.
