OCA 50EC – Automated Precision in Optical Contact Angle and Surface Energy Measurement
The OCA 50EC by DataPhysics Instruments is a fully automated optical contact angle measuring instrument, engineered for high-precision drop shape analysis and surface energy evaluation. Designed for advanced laboratories and industrial quality control environments, the OCA 50EC provides comprehensive surface characterization with exceptional accuracy and ease of use.
At the core of the OCA 50EC is a motorized sample table that moves seamlessly in X, Y, and Z directions, enabling precise sample positioning. A high-performance optical system featuring a 6.5-fold zoom lens, autofocus, and adjustable observation angle delivers sharp, high-resolution images for static and dynamic contact angle analysis.
The built-in USB 3.0 camera captures fast, high-quality video footage, essential for studying time-dependent wetting behaviors. LED illumination with both manual and software control ensures uniform lighting and includes temperature drift compensation for consistent imaging conditions.
This model supports a variety of advanced dosing systems, including electronic syringe modules and multiple direct dosing options. It can dispense nanolitre and picolitre volumes, making it ideal for evaluating microstructured and small-scale samples.
Intuitive operation is facilitated by the TP 50 touch screen control panel with a precision dial, allowing for smooth command over all electronic components.
Whether you’re measuring interfacial tension, determining surface energy, or analyzing adhesion properties, the OCA 50EC delivers precise and repeatable results, backed by modular expandability and cutting-edge technology.
The Optical contact angle measuring- OCA 50EC 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 OCA 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 6.5-fold zoom lens and the high-performance camera with USB 3 interface ensure optimal images of the deposited drops. For a fast and intuitive device control, even during complex measurements, the TP 50 control panel with touch screen and precision control wheel is included with every OCA 50.
