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.
