NMR spectrometer. Chemist loads a drug sample into a Nuclear Magnetic Resonance (NMR) spectrometer, during antibiotic drug research. The superconducting magnet of the NMR spectrometer is contained in the steel tank. This device analyses the component chemicals in the synthetically produced drug mixtures. The magnetic field of the NMR affects the atoms that make up the chemicals. In this way components in a drug mixture can be selected and tested for antibacterial activity. This research at Microcide Pharmaceuticals, California, aims to produce drugs to combat antibiotic-resistant bacteria. The ropes holding the steel tanks are an anti-earthquake precaution.
