The NORELL® NorLoc™ Generation II Security Cap™

• 5mm
• Glacier White
• 100 Pack
• Patented Design Elements Allow Safe & Secure Closure

The standard 5mm and 3mm NMR tube cap designs have existed for decades. Many users can attest to  the significant flaws inherent in the traditional NMR tube caps, especially when faced with the chore of capping numerous sample tubes.  

NorLoc™ Caps work well with any NMR tube but are best when paired with Secure Series™ NMR sample tubes from Norell®. Internal components of NorLoc™ caps engage with the security band printed on our Secure Series™ NMR tubes and indicate one of two stages of closure.

Secure Series™ High Throughput NMR Tubes 100 Pack

• 5mm
• 7 Inch (178mm)
• 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 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.

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

• 5mm
• 600MHz 
• 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.
