OCA 15EC
The OCA 15EC is the entry level measuring device for professional contact angle measurements and drop shape analysis. The sample table of the OCA 15EC can slide freely in X- and Y-direction and is locked into position with its switchable magnetic base. In Z-direction the sample table is adjustable using precision mechanics with a hand wheel. The fast 6-fold zoom lens with manual focus and adjustable observation angle in combination with the USB camera ensures pin-sharp drop images and facilitates the effortless analysis with the SCA software. With a single direct dosing system SD-DM or a double direct dosing system DD-DM liquids can be positioned and dosed with one or two electronic syringe modules ESr-N, respectively. Direct tubeless dosing of the syringe content and the ability to use cost-saving disposable syringes and needles allow for short preparation times and minimal cleaning efforts. Even though the OCA 15EC is a high precision measuring device designed for laboratory use, it is highly mobile and can effortlessly be taken apart with two star grip screws and be stored securely in a transport case. For a fast and convenient access to the surface and interfacial measurements two pre-configured packages are available. These include all necessary components to get started immediately. The OCA 15EC Package 1 consists of the base unit, a single direct dosing system SD-DM, one electronic syringe unit ESr-N and the software module SCA 20.

OCA 50
OCA 50 The OCA 50 is the fully automatic measuring device for the time-saving analysis of the wettability of solid surfaces and the determination of the surface energy of solids. The sample table of the OCA 50 can be positioned along all three directions in space via electronic high-performance axes, with both extraordinary speed and highest precision. Combined with an electronic multiple direct dosing system DDE/x and up to four electronic syringe modules ESr-N the determination of surface parameters can be automated completely. The automation of measurements succeeds easier than ever before thanks to the intuitive automation dialogue of the SCA software and its visual drop positioning system. Hence it is possible to determine, for example, the surface energy with four test liquids at different position of even large samples without any manual user intervention. This facilitates a complete and automated sample mapping. In order to map silicon wafers, electronic turn tables with vacuum fixation are available. They allow to access any position for contact angle measurements, even on 12 wafers. In any case, the 6-fold zoom lens and the high-performance camera with USB 3.0 interface ensure optimal images of the deposited drops.

With the trendsetting 10-fold zoom lens and the reliable auto focus system by DataPhysics 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 3.0 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 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.
