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. The OCA 15EC Package 2 consists of the base unit, a double direct dosing system DD-DM, two electronic syringe units ESr-N and the software module SCA 20.

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.
