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. 

5mm Valved NMR Tubes for Intermediate Pressure, 1 Pack

• 5mm
• 500MHz
• 7" (178mm)
• Heavy Wall

This valve incorporates an advanced seal design that is superior to alternative valves currently available from other manufacturers. A fluoroelastomer o-ring imparts resilience and a high degree of chemical resistance. A PTFE sheath, forming the primary seal, completely covers the fluoroelastomer o-ring, creating the ultimate barrier against aggressive, reactive substances while providing a totally inert surface.

These pressure tubes facilitate experiments requiring conditions such as pressurized inert atmosphere blanketing, addition of reactive gaseous reagents under pressure, containment of low boiling point solvents or samples at elevated temperatures, and so on.

We recommend that the maximum operating pressure should be limited to 600 kPa (6 bar, 87 psi) when using a thin wall pressure tube, up to 1200 kPa (12 bar, 175 psi) if using a heavy wall pressure tube. (Please see accompanying table for complete details).

Suprasil® Quartz NMR Sample Tubes, 1 Pack

• 5mm
• 500MHz
• 7" (178mm)

Recommended for Boron NMR [< 0.01 ppm Boron] and/or UV catalyzed reactions in the region above 190nm [90%T @ 190nm].

Fluoropolymer Liner Tube Kits for 29Si and 11B

Includes:

• 2 O-Rings
• 1 Open-Ended 5mm Tube

For Silicon and Boron NMR, we recommend the use of either TL-5-TUBEKIT for 5mm probes or TL-10-TUBEKIT for 10mm probes. Kit is designed for either Varian, Bruker, or JEOL spinners as a holding device for the fluoropolymer liner. Probe only “sees” fluoropolymer, allowing for excellent 29Si and 11B spectra.

Coaxial Inserts for NMR Sample Tube for Bruker Spectrometers
4mm Quartz Tube W/50mm STEM. Includes one S-5-400-7 NMR tube to be used with the Coaxial Insert. 

50mm Stem OD is 3mm, Stem Sample Capacity is 175μL

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

Sample Vault Series™ NMR Tubes, 96 Pack

• 5mm
• Up to 950MHz 
• 178mm
• Packed in Lots of 96
• Ships with Closed Port Sample Vault Caps

Sample Vault™ Series NMR tubes with Sample Vault™ caps (U.S. Patent No. 8,054,080), are engineered for a new generation of high-throughput lab automation systems, including the Bruker SampleJet. 

Our patented design incorporates a white band positioned on the NMR tube that aligns with the base of the cap, indicating a properly locked position. Together, our Sample Vault™ caps and Sample Vault™ tubes form an integrated closure system for fail-safe delivery of your sample into the magnet.
