DataPhysics optical contact angle measuring and contour analysis systems

Overview

Optical contact angle measurement
The 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.

Application notes

Surface energy determination on thin wires using picolitre drops
The 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.
