Edwin A. Murillo

you can use the goniometer, but it would be a comparison between your samples.

Thanks!!!

I will have a look at that.

Alain Celzard

If you have a nice membrane with a well-defined flat surface, I recommend sessile drop method. But if you have your hollow fibres in a loose packing, I definitely recommend Washburn method (capillary ascension).

Alain

Thanks Alain Celzard
