Optical contact angle measuring- OCA 15EC

OCA 15EC – Compact Precision for Optical Contact Angle and Surface Energy Analysis

The OCA 15EC from DataPhysics Instruments is a reliable, entry-level optical contact angle measuring instrument designed to deliver high-precision drop shape analysis and surface energy evaluation. Ideal for routine laboratory use, educational environments, and industrial quality control, the OCA 15EC combines affordability with advanced performance.

Built with precision engineering, the OCA 15EC features a modular sample table that can be easily adjusted both horizontally and vertically for flexible sample positioning. Its compact frame houses a USB 3 camera paired with a high-resolution optical zoom system, offering crystal-clear images for accurate contact angle measurement, even on small or irregular samples.

The system’s integrated LED illumination provides consistent lighting with software-controlled brightness and automatic compensation for temperature drift. This ensures reproducible imaging conditions for each measurement session. The instrument also supports static and dynamic contact angle measurement, as well as interfacial tension analysis and work of adhesion calculations.

The OCA 15EC supports single and double dosing with optional electronic syringe modules, enabling precise and tubeless liquid application directly to the substrate. It is also compatible with optional accessories such as the TBU 100EC tilting base for roll-off angle measurement and temperature-controlled environmental chambers.

With its user-friendly design and robust software suite, the OCA 15EC makes professional surface characterization accessible to labs of all sizes. For those seeking cost-effective yet advanced contact angle measurement, the OCA 15EC stands out as the ideal tool.

The Optical contact angle measuring- 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 6.5-fold zoom lens with manual focus and adjustable observation angle in combination with the USB 3 camera ensures pin-sharp drop images and facilitates the effortless analysis with the 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.
