Secure Series™ NMR Tubes 5 Pack

• 3mm
• 500MHz 
• 8 Inch (203mm)
• Includes “Norloc™ with Security Band” Caps
• A patented proprietary surface treatment with a unique textured surface ensures precise and positive retention in Bruker, Agilent/Varian, and Jeol spinner turbines.

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®.

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. 

Select Series™ 5mm, Ultra-Precision NMR Tubes, 5 Pack

• 5mm
• 900MHz 
• 7 Inch (178mm)
• Ships with Economy Cap. NorLoc™ Caps Sold Separately.

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. 

Constricted Standard Series NMR Sample Tubes, 1 Pack

• 5mm
• 8" (203mm)
• 500MHz
• I.D. at Constriction: 1.5mm - 2.0mm
• For Routine NMR

Available with ULTRA-THIN wall NMR Tubes.
