Medium Wall NMR Sample Tubes, 5 Pack
Medium wall (0.8 mm) NMR tubes offer a considerable increase in the margin of safety against breakage while keeping 65% of the sample volume. Can be used for student use or in auto-sampling systems. Available either constricted and/or amberized.
Select Series™ 3mm, Ultra-Precision NMR Tubes, 5 Pack
Our “Select Series™” NMR tubes are manufactured out of ASTM Type 1 Class A glass, commonly referred to as Pyrex® 7740 (Corning), Duran® (Schott Glass), or Kimax® KG-33 (Kimble) glass.
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 under any other application where large temperature variations are required in the experiment.
Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.
Standard Series™ High-Throughput NMR Tubes, 100 Pack
Our “Standard Series™” NMR tubes are manufactured out of ASTM Type 1 Class B glass, commonly referred to as N-51A. Applications that are suited for using this type of glass are routine NMR where samples are run under room temperatures with no thermal gradients. It is therefore not recommended to fuse this glass with standard vacuum manifolds and the like, since these are generally made out of Type 1 Class A glass. Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.
Economy NMR Tube Caps, 100 PackOur economy NMR tube caps are now available in 12 different colors for better solvent labeling capabilities.
5mm, Thin Wall, Natural Quartz NMR Sample Tubes, 5 PackRecommended for Boron NMR [< 0.1 ppm Boron] and/or UV catalyzed reactions in the region above 210nm [90%T @ 210nm]. Medium and heavy wall NMR tubes are now available, in addition to standard, thin wall NMR tubes.
Secure Series™ NMR Tubes 5 Pack
The Secure 55 Series™ NMR tubes are made from ASTM Type I Class B borosilicate glass ("high expansion" borosilicate glass such as Kimble N-51A or equivalent) and parallel the properties of the Standard Series™ NMR tubes from Norell®
Secure Series™ NMR tubes feature several patented design elements that add a superior level of sample containment and isolation, safeguarding the integrity of precious or critical NMR samples and assuring secure retention of the NMR tube in the spinner turbine.
Secure Series™ NMR Tubes ship with our patented NorLoc Caps™ featuring a Security Band™ that engages and locks into the NorLoc II Security Cap™, securely joining the cap to the NMR tube.
