The Deuteration Network (DeuNet) is an international network of deuteration facilities and laboratories which aims to facilitate access to deuteration services and customised deuterium labelling of molecules and biomolecules for use in neutron research and in other characterisation techniques.

DeuNet endeavours to become a central hub for access to deuteration research around the world, deuteration information and research outcomes that are enabled by deuterium labelling.  The network promotes collaborations between deuteration laboratories, facilitates the development of new methods for deuteration, and increases the visibility of its members to researchers and research facilities that benefit from deuteration science. The network also facilitates communication between each of the DeuNet members and their collaborators through regular meeting and user workshops.
