About us

Our experience in the investigation of nanomaterials makes us experts for research projects and the chemical industry. We investigate nanomaterials for their registration as well as for use in the optimization of technologies. With constantly growing knowledge, the most up-to-date methods and the most modern laboratory equipment, we determine the physicochemical properties (e.g. particle size distribution) of nanomaterials and their environmental fate (e.g. dissolution rate, dispersion stability).We conduct ecotoxicological studies specifically for nanomaterials, i.e. accompanied by the appropriate analytics and with adapted study design.

Nanoparticle tracking for particle size distribution of dispersions

Dissolution rate testing according to OECD GD 29 and 318 or EFSA Guidance

Highly scientificly educated study directors

We work for your registration

We have a GLP certificate
