Optical Contact Angle – 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 6.5-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. 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.
