Experimental arrangement for NMR of biofilms. The illustrations show (from left to right): the vertical bore superconducting magnet with perfusion lines leading to the bottom-loaded NMR probe; a cutaway view of the custom NMR probe, shown holding the NMR biofilm reactor; an external view of the NMR biofilm reactor; and a cutaway view of the NMR biofilm reactor containing a perfused biofilm (medium flowing against gravity).
