NMR studies of aerobic cell metabolism require that spectral data of high sensitivity and resolution be acquired from samples maintained under suitable conditions. The loop‐gap resonator 31 P NMR probe described here was designed for investigations of highly aerobic‐dependent renal proximal tubules in an environment similar to those of conventional incubation flasks. The inherently higher sensitivity of the loop‐gap resonator design and associated circuitry made it possible to obtain adequate spectra in short periods of time with small amounts of sample. Cellular physiological properties of perifused aerobic renal proximal tubule cell suspensions in the loop‐gap resonator probe were found to be similar to equivalent tissue samples incubated in conventional flasks. Furthermore, the loop‐gap perifusion probe was found to provide useful 31 P NMR spectra of the kidney tubule system after acquisition times as short as 3 min.
