Surface Tensiometer

Surface tension and interfacial tension are fundamental physical properties governing wetting, spreading, adhesion, foaming, emulsification, dispersion, and permeability of liquids and solids. These phenomena directly impact the performance of coatings, inks, detergents, cosmetics, pharmaceuticals, plating solutions, lubricants, semiconductor processes, and food products.

The liquid surface tension is the characteristic of liquids to minimize their surface to the smallest possible area, which would result in a perfectly spherical shape. Measuring surface tension allows characterizing different properties like wettability, permeability, solubility, foamability, emulsifiability, dispersibility, etc.
