The Drop Bubble Shape Tensiometer PAT-1 is well suited to determine the contact angle of liquids on a solid surface. The apparatus is driven by modern software.
The addition of various modular options allows the measurement of contact angle, surface rheology, elasticity, viscosity, iso-dense liquid / liquid systems, short time interfacial tension, direct drop/drop, bubble/bubble and drop/bubble interactions and fast oscillations.
Applications : surfactants, detergents, pharmaceutical, cosmetics, food, medicine and biology, ecology.
