Contact angle measuring and contour analysis systems for every budget. State-of-the-art optics, high-precision mechanical systems, intelligent electronic controllers and high-resolution video cameras guarantee a precise, accurate and highly reproducible image of a liquid drop dispensed within the DataPhysics instrument selected.
The OCA 25 is the all-purpose measuring device for contact angle measurements and the drop shape analysis. To cope with special requirements of the measuring environment e.g. for aeronautic or enhanced oil recovery research, special models of the OCA 25 are available to measure at high temperatures, low or high pressures.
The OCA 50 is the measuring device for the fully automatic, time-saving analysis of the wettability of solid surfaces and the determination of the surface energy of solids. Due to the motorized sample table, measuring procedures can be automated easily and thus the surface properties of objects, e.g. large area wafers, can be analysed at the push of a button.
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.
