NORELL™ Select Series™ Amber NMR Tubes offer photosensitive materials protection from visible and ultraviolet radiation. Typical absorbance (ABS) is between 0.5 and 1.0 from 650 to 300nm and is greater than 1.0 from 300 to 190nm. These tubes are manufactured out of ASTM Type 1 Class A glass, commonly referred to as Pyrex® 7740 (Corning), Duran® (Schott Glass), or Kimax® (Kimble) KG-33 glass. Several key properties that make this glass type desirable for NMR are its high degree of thermal shock resistance and low expansion coefficient. This allows for a greater margin of safety from breakage when used in variable temperature applications and freeze/thaw cycling, or any other application where large temperature variations are required in the experiment.
