The products by DataPhysics Germany are the latest state-of-the-art in contact angle and tensiometer devices.
Video-supported contact angle measuring instrument OCA are the top instrument from the comprehensive modular "OCA construction kit". It is characterized by a multitude of technical detail solutions in mechanical, optical and electronical components and by its powerful software modules.
It was developed for the measurement of the static and dynamic contact angles according to the "Sessile & Captive Drop Method" and the "Pendant Drop Method", to determine the surface free energy of solid bodies and their components as well as for determining the surface and interface tension of liquids from the drop or lamella contour.
Other proposed methods incoroperated with the instrumentation by DataPhysics are : Single fiber contact angle, Wilhelmy plate method, powder contact angle, spinning drop method, Du-Nouy ring method, drop volume method and bubble pressure method.
