Abstract

642,962. Testing surface tension of liquids. MERRY, G. Oct. 30, 1947, No. 28964. Convention date, Oct. 15, 1946. [Class 106 (ii)] A pipette for the direct measurement of surface tension comprises a tube 1, having a capillary bore, provided with a scale graduated in surface tension units. It may be provided with a bulbous portion 3 in which is an air vent 4. The end of the tube 1 is inserted into the liquid to be tested, and the height to which the liquid rises in the tube is a measure of the surface tension. The lower part of the tube 1 may have a larger diameter bore than the upper, scaled part. The scale may be marked directly on the tube or on a separate support..
