The laboratory was founded in 1964 by Dr. Gerhard Graner, which established a laboratory for analytical testing of drugs, pharmaceutical raw materials and foodstuffs as a pharmacist. Based on the obtained results, test certificates or quality dossiers could be then created for drug approvals. As a publicly appointed sworn expert Mr Gerhard Graner also was able to compile a final report for the approval of drugs.

Since July 2007, the CAU Analytics is integrated in our laboratory, whitin which previously consist a close cooperation in the consolidated companies of the Sakosta Holding AG.
