Optical Contact Angle

OCA 200


The OCA 200 is the contact angle measuring and drop contour analysis system for microscopic and macroscopic structures. For the analysis of micro-structured samples the nanolitre dosing system is available which can generate down to 10 nanolitre small droplets. These droplets are small enough to fit, for example, between the screw threads of a dental implant whose surface is to be analysed. Even smaller structures can be analysed using the picolitre dosing system PDDS which can dose down to 30 picolitre small droplets. These allow contact angle measurement, for example, on the individual wires of the mesh structure of a coronary stent or on single fibres.
