3D-Printable centrifugal devices for biomolecular solid state NMR rotors.

The advent of magic angle spinning (MAS) rates exceeding 100 kHz has facilitated the acquisition of H-detected solid-state NMR spectra of biomolecules with high resolution. However, challenges can arise when preparing rotors for these experiments, due to the physical properties of biomolecular solid samples and the small dimensions of the rotors. In this study, we have designed 3D-printable centrifugal devices that facilitate efficient and consistent packing of crystalline protein slurries or viscous phospholipids into 0.
