The OCA 200 is the contact angle goniometer and drop shape analysis system for microscopic and macroscopic structures. The software-controlled, electrically driven optic alignment enables the OCA 200 to adjust the observation angle and to focus automatically. With the trendsetting 10-fold zoom lens and the reliable auto focus system by Data Physics Instruments, the OCA 200 is equipped to handle any kind of sample size from a macroscopic silicon wafer to the microscopic mesh structure of a coronary stent. In combination with the high-performance camera with USB 3 interface even smallest drops of highly volatile liquids can be monitored. The electrically driven sample table makes it possible to position micro-structured samples with highest precision and exceptional speed for fast automated measuring procedures. With an electronic multiple direct dosing system DDE/x and up to four electronic syringe modules ESr-N liquids can be deposited on a macroscopic sample and its surface parameters can be determined automatically. For the analysis of micro-structured samples the nanoliter dosing system is available which can generate down to 10 nanoliter small droplets. These droplets are small enough to fit, for example, between the screw threads of a dental implant whose surface is to be analyzed. Even smaller structures can be analyzed using the picoliter dosing system PDDS which can dose down to 30 picoliter small droplets. These allow contact angle measurement, for example, on the individual wires of the mesh structure of a coronary stent or on single fibers.
