Résumé

A surface tension analyzer specially designed to handle volatile fluids such as R134a has been designed and constructed. A relatively simple and practical method was developed to measure the surface tension of a small sample of volatile liquid, and to determine whether it had become contaminated with dissolved oil, grease or a surface active agent. The maximum bubble pressure method was selected and the apparatus constructed was tested using distilled water and methanol. Measurements for water, methanol and R134a are presented. The uncertainty of the measurements is less than plus or minus 2%.
