Contact Angle Meters of the OCA-series

About

The optical contact angle meters of the OCA series from DataPhysics Instruments are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems.

Possible Measurements:
- static contact angle (sessile drop method, captive bubble method, sessile drop in top view)
- dynamic contact angle (roll-off contact angle and needle-in method)
- analysis of interfacial and surface tension with dispersive and polar parts (pendant drop method)
- analysis of surface energy with dispersive and polar parts (sessile drop method; manual or automatic measuring procedure with several test liquids, depending on model)
- analysis of the viscoelastic modulus (oscillating drop method)
- analysis of the work of adhesion
