DESCRIPTION
The Data Physics OCA 25 is an all-purpose measuring device for content analog measurements and drop shape analysis.
The optical analysis of liquid droplets that hang from a dosing needle or are placed on a solid surface facilitates the determination of different surface and interfacial parameters. The contact angle characterizes the solid’s wetting behavior with a given liquid.
The instrument’s software is designed to take measurements of the contact angles of multiple test liquids to calculate the surface energy of the solid and the work of adhesion for different liquids. The instrument includes a tilting base to allow for advancing and receding dynamic contact angle measurements and an oscillating drop generator to measure interfacial rheology.
The reliable and experimentally robust measurement of the contact angle aids on the development of surface coatings, composite materials, paints and varnishes or cleaning agents. The measurement of contact angle helps research projects that require precise understanding and control of wetting and adhesion properties.
