DataPhysics optical contact angle measuring and contour analysis systems Vertical Tabs Overview Optical contact angle measurementThe optical analysis of drops 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 that a liquid drop establishes on a solid surface characterises the solid’s wetting behaviour with said liquid.Read more > Application notes Surface energy determination on thin wires using picolitre dropsThe surface energies of a tinned and a pure copper wire were determined measuring contact angles with various liquids using the DataPhysics optical contact angle measuring and contour analysis system OCA 200 in combination with the picolitre dosing system PDDS.Read more >> Download Application note, One-click surface energy determination with DataPhysics pressure-based double dosing system DDS-P for the OCA series.pdf (365.21 KB)One-click surface energy determination with DataPhysics pressure-based double dosing system DDS-P for the OCA series Date of creation: 2 January 2024 Library code: 13617 Download Application note, Surface energy analysis for the verification of treatment effects on different polymer substrates.pdf (330.44 KB)Surface energy analysis for the verification of treatment effects on different polymer substrates Date of creation: 2 January 2024 Library code: 13618 Literature DataPhysics OCA product seriesThe optical contact angle measuring and contour analysis systems of the OCA series combine high resolution optics, exact liquid dosing and precise sample positioning into powerful and reliable measuring systems.Readmore >>
