CLS-logo.png Concept Life Sciences offers a comprehensive range of  physicochemical parameter testing  methods, including those described in the OECD Test Guidelines for Chemicals and the CIPAC Handbooks.

These tests, and the information they generate, are essential for the registration of plant protection products and biocides in the EU, UK and other countries. The tests are also used for approval under the EU and UK REACH regulations. Our multi-disciplinary teams of scientists can work with you to identify and deliver the best combination of tests to meet your needs.
