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.

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

• 5mm
• 400MHz 
• 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.

The NORELL® NorLoc™ Generation II Security Cap™

• 5mm
• Red Poppy
• 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. 

Redesigned Fluoropolymer NMR Tube Caps

• 5mm
• 50 Pack
• White

Redesigned tapered fluoropolymer closure system that works together with our fire-polished tube ends, offering superior sealing and sample integrity, preventing sample loss even during temperature gradients.
