About CleanControlling Medical

CleanControlling Medical stands for comprehensive expertise in the field of biological and microbiological hygienic testing of medical devices. The intensive exchange with the parties involved in approval procedures and the clear understanding of customer requirements ensures targeted testing strategies.

As an accredited (acc. DIN EN ISO / IEC 17025), certified (GLP) and approved (ZLG) testing laboratory, CleanControlling Medical offers a full range of high-quality laboratory services.


Laboratory Services

The range of services includes tests to determine the biocompatibility according to the amendment of DIN EN ISO 10993-1, tests for the validation and monitoring of cleaning processes, determination of particulate cleanliness, tests within the validation of reprocessing and sterilization instructions, life tests as well as tests for determination the chemical surface cleanliness.

The new European Medical Devices Regulation (EU-MDR) leads to changes in the classification of medical devices by risk classes. These changes mean a recertification of products for a large number of medical device manufacturers, which must be available by the end of the transition period on 26 May 2020. The necessary risk assessments, audits and documentation increasingly present major organizational and temporal challenges to manufacturers and consultative and auditing bodies.

CleanControlling Medical has adapted to the challenges and prepared itself with accredited testing procedures as well as the necessary testing capacities and the expansion of the laboratory infrastructure with around 500 m² of laboratory premises and with state-of-the-art equipment. The expansion and furnishing of the laboratory premises were implemented and accredited end of 2018.
