For more than 25 years the Hydrotox GmbH offers competent consultancy and experimental services for the assessment of single substances and mixtures. Our services encompass investigation in the field of biological degradation, ecotoxicology and genotoxicity. The Hydrotox laboratory is GLP-certified for these three fields since 1992 and works according to national and international guidelines (DIN, ISO, OECD, OSPAR, EPA). By combining laboratory investigations with specific data surveys and grading the test in “full scale”-, “range finding”- and “limit” tests, we maximise information yields and reduce efforts and costs. Whether you need our services for registration of your products, for quality assurance or for regulatory water monitoring, we always provide individual consulting and adapt the test design to the specific requirements of the test substance or regulatory needs and according to your wishes. Our experts are pleased to support you with the registration of your products and advise you in prevailing legal norms. Furthermore, we offer consultancy and data research studies for diverse environmental relevant topics, such as application for eco-labels and compliances with regulations on waste water treatment.
