Optical Contact Angle

OCA 200

The OCA 200 from Dataphysics can measure contact angle and drop contour for microscopic and macroscopic structures. A nanolitre dosing system down to 10 nanolitre small droplets is suitable for the analysis of micro-structured samples for eg. Screw threads of a dental implant.

Even smaller structures can be analyzed with the picolitre dosing system PDDS which can dose down to 30 picolitre small droplets for eg. Individual wires of the mesh structure of a coronary stent or on single fibres.
