4mm TUBE W/50mm STEM. Includes one S-5-400-7 NMR tube to be used with the Coaxial Insert. 

50mm Stem OD is 2mm, Stem Sample Capacity is 100μL

Please note: we cannot guarantee the fit of any NMR tube other than the one that is provided with the insert.

Standard Series™ Ultra-Precision NMR Tubes, 5 Pack

• 5mm
• 600MHz 
• 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.

Screw-Cap NMR Sample Tubes, 1 Pack 
Screw-Cap Septum NMR Tubes offer both convenience of a screw cap and that of a septum where material can be removed. Convenient screw-cap access with the security of a fluoropolymer (PTFE) seal. Supplied with open top cap & fluoropolymer/silicone septum for quick and clean access with a 22 gauge standard point needle.   

• 5mm
• 7" (178mm)
• 600 MHz
• Each Screw-Cap Tube comes complete with open top Polypropylene screw cap and PTFE/Silicone septum 
• Inert to most organic solvents and compounds but not recommended for use with strongly corrosive materials 
• Not recommended for multiple punctures

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

• 5mm
• 500MHz 
• 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. 

4mm, Standard, Natural Quartz EPR Sample Tubes, 5 Pack
Norell EPR tubes produce lower background signals and have better resistance to breakage than competitor brands. Our proprietary technical treatment reduces background noise along with the benefit of protecting against tube breakage. 

Additionally, we have designed a new fluoropolymer closure system around our fire-polished tube ends that prevents sample loss during temperature gradients. Available in both standard and ultra precision. Supplied with tapered  fluoropolymer caps.
