The ZFMK Biobank is a specialized archive storing ultra-deep frozen animal samples (e.g. DNA and tissue) for non-commercial molecular research. The biobank is closely linked to the morphological collections of the museum.
There are about 300,000 specimens in the collection, including type material. The section also houses collections or parts of collections of Erwin M. Beyer, Bernhard Mannheim, Hermann Schmitz, Hans Mendl and Hans Ulrich.
In the Hymenoptera section, additional to the Hymenoptera, the following collections of organisms are curated: Heteroptera, "Homoptera", Orthopteroidea (heterogeneous collection including Mantodea, Blattodea, Phasmatodea, Dermaptera, and Saltatoria), Phthiraptera and Siphonaptera.
The collection is still 'under construction', containing around 12.000 specimens, many in absolute alcohol for DNA studies. The pill millipedes of the order Glomerida and Sphaerotheiida are well represented. A digitalisation of the collection is currently underway.
In 1977, a historical very valuable collection with appr. 5000 specimens from the Zoological Museum of the Göttingen University was brought to Bonn and thus was saved from being ruined, but was instead again accessible to the scientific public.
The focus of the collection of preserved mammals are small mammals of the Palearctic and Africa. Of special international significance are the African collections, together with the museums in Berlin, Frankfurt and Stuttgart.
