Description

NMR Tube, 5mm, Norell, Secure 33 Series, 8″ Long, 500 MHz, Concentricity 0.0050mm, Camber +/- 0.0130mm. The Secure 33 Series™ NMR tubes are made from ASTM Type I Class A borosilicate glass (“low expansion” borosilicate glass such as Corning Pyrex® 7740 or equivalent) and match the properties of the Select Series™ NMR tubes from Norell. Because of the low coefficient of thermal expansion, Secure 33 Series™ NMR tubes show a high degree of thermal shock resistance, a necessary attribute to prevent breakage when large temperature variations are expected in variable temperature studies, degassing samples through freeze-pump-thaw cycles, etc. Tubes are supplied with the cap color in the picture (Royal Blue). Please Note: other cap colors are available, please contact us for details. Made in the United States.
