A quick approach to measure the surface tension of PCL and Chloroform blend is required since chloroform is highly volatile.
Du Noüy ring in enclosed vessel to reduce evaporation. BTW, you need to choose an alternative material than chloroform. Have you heard of the Montreal Protocol?

The dunoy ring method with a tensiometer.

Thank you for the reply. I will surely look into the above mentioned technique and information!
Do you think Du Noüy Padday method is more suitable for measuring surface tension of my polymer solution? since I want to use as less as solution as possible!
Thanks
You may then want to attempt the capillary rise method with a narrow tube: https://web.mst.edu/~gbert/SurfaceTension/back.htm
