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.
