Deuteration and Macromolecular Crystallisation (DEMAX) at ESS

The ESS DEMAX platform produces deuterated materials such as biomass, proteins, lipids and other small molecules for neutron techniques such as small angle scattering, reflectometry, protein crystallography, spectroscopy, and powder diffraction. DEMAX also supports crystallisation optimisation for large protein crystal growth (protiated and/or perdeuterated) for crystallography.

Scientists can submit proposals for deuterated materials for use in their neutron experiments at other facilities. Access is based upon peer review of proposals and scientific merit and is currently not limited to ESS member countries. The next call for proposals will be advertised at For more information email
