OCA 25 is an all-purpose measuring device for contact angle measurements and drop shape analysis. It combines high resolution optics, exact liquid dosing, and precise sample positioning into powerful and reliable measuring systems. The sample table of it is adjustable along all three directions in space via precision axes with hand wheels, thus always guaranteeing a fast and accurate manual positioning of the sample. Analysis of even the fastest processes is possible recording up to 3250 frames/s using the 6.5-fold zoom lens and the high-performance camera with USB 3 interface.
