5mm, 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.

The NORELL® NorLoc™ Generation II Security Cap™

• 5mm
• Sea Glass
• 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. 

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

• 5mm
• 500MHz 
• 8 Inch (203mm)
• 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. 

Amberized Standard Series NMR Sample Tubes, 1 Pack

• 5mm
• 7" (178mm)
• 600MHz
• For Routine NMR

Available with ULTRA-THIN wall NMR Tubes.

Pictured with optional NorLoc™ Cap. Amberized NMR tubes ship with economy caps. 

Silicone Rubber Stoppers for NMR Sample Tubes

• Clear/Translucent
• Will fit our thin wall tubes having an O.D. of 1.5mm to 3mm. (1.2mm to 2.4mm I.D.)
• Packed in Lots of 50

These stoppers can provide a solution for those difficult situations when a standard tube cap cannot be used, as, for instance, when space is a limiting factor.

Heavy Wall NMR Sample Tubes, 5 Pack

• 5mm
• Up to 500MHz
• 7" (178mm)

Heavy wall (1.4 mm) NMR tubes offer the ultimate protection from breakage, either through rapid changes in temperature or pressure, or from mishandling. Recommended for use with hazardous or radioactive samples, where sample containment is critical. Available either constricted and/or amberized.

Bruker Match System NMR Tubes, 5 Pack

• 3mm
• Sample Volume - 160μl
• 100mm Length
• O.D. - 2.99mm
• I.D. - 2.41mm

Ultra-Precision, machined NMR tubes specifically made for the Bruker MATCH™ System.

Thin-Wall Transparent Fluoropolymer FEP Tubing

• 3.52mm O.D. x 3mm I.D.
• 12" Length (305mm)
• Packed in Lots of 4

Our thin-wall transparent fluoropolymer FEP tubing is manufactured from special virgin grade DuPont thermoplastic FEP fluoropolymer. Unlike PTFE tubing, this material can be heat sealed. This property offers extremely large possibilities for packaging and/or storage of samples (corrosives, liquids, solids, etc.). Our fluoropolymer tubing can also be used where snug and tight fit over glass or metal tubing is required.
