Zwisler Laboratorium History
Zwisler Laboratorium GmbH was founded in 2001, headquartered in Reichenau, Germany. Over the years, the lab built its reputation as a partner in microbiological testing, hygiene monitoring, validation of reprocessing processes, in vitro pyrogen (MAT/IPT) assays, and microbial integrity testing.
In August 2020, Zwisler moved into new, expanded laboratory and office premises to increase capacity and modernise its facilities. In December 2024, Zwisler officially became part of Cormica, marking Cormica’s entry into the German market and strengthening its European footprint.
Under the new structure, Zwisler continues its focus on microbiological testing and in vitro assay innovation while benefiting from integration into Cormica’s broader network of testing services and global regulatory support.
