Contact angle (Static, Dynamic, Tilted, Surface tension and Free Surface Energy)

Description:
This equipment allows an optical static and dynamic contact angle measurement and drop contour analysis. It enables the determination of surface and interfacial tension through pendent drop methods and determination of the surface energy of solids through test liquids whose surface tensions including their dispersive and polar parts are known. Its equipped with a tilting base unit that automatically tilts the entire device and an environmental chamber that allows to obtained measurements with control of temperature and humidity. The software also permits to measure contact angles in millimetric fibers.
