Drop shape analysis (DSA) is an image analysis method for determining the contact angle from the shadow image of a sessile drop and the surface tension or interfacial tension from the shadow image of a pendant drop.

Drop Shape analysers in combination with ADVANCE software enable comprehensive wetting and adhesion analysis of all types of surfaces – wafers, polymers, glass, ceramics, wood, paper, or metal. 

Depending on the configuration/model, the software supports every degree of automization up to full software control of surface free energy (SFE) measurement, SFE mapping, or tilting experiments. Using our liquid needle dosing technique, ADVANCE even accesses the SFE within a second. 

Optional accessories for wetting measurements at higher temperatures and manifold upgrade options enhance the spectrum of the instrument.
