This study addresses the problem of significant errors in measuring liquid surface tension coefficients using the traditional pull-off method. The improved apparatus retains the pull-off methods advantages—such as simple operation and a straightforward structure—and innovatively incorporates a horizontal adjustment module, a peristaltic pump system, and a thermostatic water bath. Experimental results show that the improved device enhances measurement precision by reducing the relative error to 0.5%. This advancement provides a more accurate and reliable approach for measuring liquid surface tension coefficients in general physics experimental teaching, which is crucial for improving the quality of experimental education.
