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. 

Sample Vault Series™ NMR Tubes, 96 Pack

• 5mm
• Up to 700MHz 
• 103.5mm
• Packed in Lots of 96
• Ships with Closed Port Sample Vault Caps

Sample Vault™ Series NMR tubes with Sample Vault™ caps (U.S. Patent No. 8,054,080), are engineered for a new generation of high-throughput lab automation systems, including the Bruker SampleJet. 

Our patented design incorporates a white band positioned on the NMR tube that aligns with the base of the cap, indicating a properly locked position. Together, our Sample Vault™ caps and Sample Vault™ tubes form an integrated closure system for fail-safe delivery of your sample into the magnet.

Standard Series™ High-Throughput NMR Tubes, 50 Pack

• 5mm
• High-Throughput
• 7 Inch (178mm)
• For Routine NMR

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.
