Several commercial UF-membranes are characterized by water contact angles. Two different methods of contact angle measurements, the sessile drop and the captive bubble methods, are compared. Differences in results between the two methods occur for the DDS CR 61 membrane; otherwise the methods give r

## Abstract A survey is given of the existing methods for measuring the surface tension from the geometry of sessile drops. These methods, which generally consist of the measurement of simple drop dimensions, are insufficiently accurate for use with adsorption studies. A new procedure is described
