Testing laboratory ASSESS-MED
Independent product testing for extracorporeal therapy systems – in accordance with regulatory requirements, industry-focused, and research-based.
About ASSESS-MED
The ASSESS-MED laboratory is part of the Extracorporeal Therapy Systems department at the Fraunhofer IZI, Rostock branch. It offers standardized, industry-oriented product testing in the field of blood purification to support a faster transfer of new technologies to the market. The laboratory conducts manufacturer-independent tests of blood purification products such as dialyzers, hemofilters, and adsorbers, and operates according to specific product standards for testing medical devices, such as DIN EN ISO 8637-1 to -3.
Through close scientific cooperation with the Rostock University Medical Center, in particular with the Section for Nephrology and its affiliated dialysis unit (Prof. Dr. med. Steffen Mitzner, Dr. med. Sebastian Koball) and the Department of Anesthesiology and Intensive Care Medicine (Prof. Dr. med. Christian Schewe, PD Dr. med. Gerd Klinkmann), a powerful alliance of applied research, clinical expertise, and industrial testing practice is formed.
ASSESS-MED is funded by the European Union through the European Regional Development Fund (ERDF) as well as the Ministry of Economics, Employment and Health of the state of Mecklenburg-Vorpommern.

Accreditation & quality management
Accredited Performance Evaluation of Dialyzers
On May 7, 2026, the Deutsche Akkreditierungsstelle (DAkkS) granted our testing laboratory accreditation under number D-PL-11140-32. The scope of accreditation covers the performance evaluation of dialyzers (clearance only) in accordance with DIN EN ISO 8637-1:2020.
We have been conducting the relevant test procedures, such as performance evaluation in accordance with DIN EN ISO 8637-1, under our ISO/IEC 17025:2018 quality management system (QMS) for some time.
Under review: DAkkS is currently reviewing an application to extend the scope of accreditation to include endotoxin transfer in accordance with ISO 8637-1:2024 (Annex A). We will provide an update here once the scope extension process is complete.
Cooperation models
The ASSESS-MED testing laboratory offers various forms of collaboration, ranging from:
- Testing orders according to standards or individual specifications
- Consulting on product-related issues
- Joint development projects (e.g., ZIM, KMU-innovativ)
- Support of preclinical and clinical studies in cooperation with the Rostock University Medical Center
