sifin diagnostics gmbh has emerged from the former ‚Staatliches Institut für Immunpräparate und Nährmedien‘ of the GDR. Thanks to investments of a German family of entrepreneurs in 1992, the diagnostics division (microbiology and blood group serology) could survive after the reunification. Since then, sifin diagnostics gmbh has recorded constant growth and is firmly embedded in the diagnostic industry. The company is still family owned. In the past few years we have strengthened our export activities and especially developed the markets in Europe and Asia. sifin diagnostics gmbh offers more than 600 standard products in the area of microbiology and immunology. We are a privately owned company, manufacturing and distributing worldwide a broad range of microbiological and immunological products.
