For micro- and macro-structured samples, the OCA 200 will be an ideal option for contour analysis and contact angle measurement. The instrument’s built-in nanoliter dosing system is capable of producing droplets down to 10 nanoliters, small enough to fit the screw threads of a dental implant whose surface is to be analysed, for example. In addition, the picolite dosing system PDS (as small as 30 picolite drops) will support the contact angle measurement of even smaller structures, such as on individual wires of the mesh structure of a coronary stent or on single fibres.
