See Available Modules
The unique 3D Topography module takes wettability and adhesion analysis to a completely new level by measuring both contact angle and surface roughness of the sample in a single measurement.
The High Pressure Chamber is designed for wettability research within enhanced oil recovery and enables measurements at pressures up to 400 bars and temperatures up to 200°C.
A software controlled tilting cradle. Used for studying dynamic contact angles. Tilting range from 0 to 90° and tilting resolution 0.1°.
Software controlled drop size pulsing for interfacial rheology measurement of viscoelastic properties of interfacial layers at liquid-air or liquid-liquid interfaces.
Utilize automated picoliter-scale drop formation. Especially useful for inkjet applications and for measuring contact angle on very small sample areas.
