Optical tensiometer Theta Topography

for angle measurementfor interfacial rheologyfor surface and interfacial tension measurement

Innovative contact angle meter capable of studying surface roughness and adjusting the result accordingly. What you can measure Roughness-corrected contact angle and 3D surface roughness Fringe projection phase shifting method Interfacial dilatational rheology Pulsating drop method Static contact angle Sessile drop, captive bubble and meniscus methods Dynamic contact angle Dynamic contact angle, advancing and receding contact angle, contact angle hysteresis and roll-off angle Surface free energy Sessile drop, captive bubble and meniscus methods Surface- and interfacial tension Pendant drop and reverse pendant drop methods 3 reasons to invest Innovative instrument Behind Theta Topography stands our premium tensiometer Theta Flow, with added functionality. The innovative Theta Topography lets you peek at the surface like never before. Surface roughness can be displayed in both 2D and 3D. Integrated method You are able to define contact angle and surface roughness accurately from the same location. Combine surface chemical and topographical data with automated software calculations. Better comparisons When your contact angle and surface free energy results are roughness-corrected, it is possible to distinguish the effect of surface chemistry and surface roughness on wettability. This is important for example when working with coatings or surface treatments.
