A new and highly improved apparatus for the direct measurement of interfacial tensions by the drop weight method has been devised. By means of an automatic recording device, measurements may be conveniently made on larger volumes and at slower dropping speeds than were heretofore possible. This is particularly valuable when measuring interfacial tensions between liquids containing surface active solutes.
