✦ Synopsis

tem the position at which the experiment is started is very The configurations of the interfacial menisci around a sphere important. Some people have used the contact position as during the pulling process were analyzed and the methods for the the beginning position, some have used the so-called half simultaneous determination of surface and interfacial tension and sphere as the beginning position, and some have used the contact angle were discussed. Furthermore, a method for the deterimmersed position as the beginning position. Which one is mination of contact angle using sphere tensiometry, which is indethe most rational? Only with the help of the configurations pendent of interfacial tension, was developed and tested with exof the interfacial menisci around a sphere can this question periments. α­§ 1997 Academic Press be answered correctly. Hence it is time to analyze the configurations of the interfacial menisci around a sphere during the pulling process, which is done in the next section. To

In this paper, a new method of determining the surface tension of the solid material that a microporous membrane is made from is introduced. The method is based on the well known determination of the so-called contact angle that is formed on the solid/liquid/gaseous three phase line. A nonideal stat
