DURAN® NMR Tubes, Scientific with Retrace Code, 500 MHz

for four application frequencies, with closures
  • Close tolerances and accuracy, especially to their straightness, wall thickness and wall thickness distribution
  • Supplied with cap
Product Overview
Nuclear magnetic resonance spectroscopy (NMR-spectroscopy) is a spectroscopic method to elucidate the structure of molecules and compounds. Due to electronic interactions of single atoms with the neighbouring atoms, structural conclusions can be drawn. In addition to structure elucidation, the concentration and dynamics of molecules can be determined with this method. This analytical method requires very precise tubes with a constant diameter, a uniform wall thickness and excellent straightness across the entire tube. NMR tubes, the sample or solution vessels for resonance frequency measurement, are extremely precise and are subject to narrow tolerances for straightness, wall thickness and wall thickness distribution.
