DataPhysics Instruments GmbH is a German company from the Stuttgart region. It has been developing, manufacturing, and distributing laboratory measuring devices for the characterisation of interfaces and surfaces for over 25 years. With 45 employees, and a worldwide distribution network, the company is one of the leading manufacturers of analytical, high-precision systems in this field.

In short, the laboratory measuring devices from DataPhysics Instruments are used whenever a liquid meets another liquid or a solid. More precisely, the devices can be used to determine important physical and chemical parameters such as surface tension and surface energy, force of adhesion, static and dynamic contact angles, roughness, zeta potential, and destabilisation mechanisms.

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.
- 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.
- 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 zeta potential, of plate-shaped solids, membranes, fibre bundles, and powders.
- humidity generators of the HGC series - for the control and adjustment of relative humidity in small measuring chambers
