The product portfolio includes:

contact angle meters of the OCA series - optical measuring systems for determining many parameters of interfaces and surfaces, such as surface tension and energy, interfacial tension, as well as static and dynamic contact angles.
portable contact angle meter PCA 200 – autonomous, hand-held device for contact angle and surface energy measurements on the go and on surfaces of any size, perfect for quality control processes
tensiometers of the DCAT series - force-based instruments for investigating a number of interface and surface parameters, such as surface tension and energy, interfacial tension, dynamic contact angle, as well as critical micelle formation concentration and force of adhesion.
MBP 200 bubble pressure tensiometer - using the maximum bubble pressure method to determine the dynamic surface tension of rapidly generated surfaces.
SVT 25 spinning drop tensiometer - for characterising extremely low interfacial tensions between two liquids and interfacial rheology.
MultiScan MS 20 dispersion stability analysis system - for investigating the stability of multiphase mixtures such as emulsions and suspensions, regarding their long-term storage stability and their destabilisation mechanisms.
ZPA 20 zeta potential analyzer - with patented measuring method for the precise determination of the surface potential, or zeta potential, of plate-shaped solids, membranes, fibre bundles, and powders.
SPA 25 surface profilometer - for the creation of surface profiles as well as the analysis of roughness parameters.
humidity generators of the HGC series - for the precise control and adjustment of relative humidity in small and medium-sized measuring chambers.
