FIELD: measuring.
SUBSTANCE: invention relates to methods and apparatus for measuring the surface tension of liquids. Method for measuring the surface tension consists in bringing an object with a flat horizontal bottom surface or a frame located in a horizontal plane into contact with a liquid by means of a manual or electric microlift, then lifting the object or the frame until separation from the liquid, while measuring the maximum separation force or the maximum distance from the surface of the liquid whereat the separation occurs.
EFFECT: increase in the accuracy of determining the surface tension and the speed of delivering the results, as well as expansion of the range of engineering means for this purpose.
