Ecotoxicological tests

Our contribution to your safety


The numerous test methods pursuant to DIN/ ISO standards and OECD guidelines performed in our laboratories are the general basis for our toxicological evaluations. We only use standardized testing methods which are in accordance with national and international standards and are approved by the responsible authorities. As a result, we offer our clients maximum safety for their projects.
