Select Series™ 3mm, Ultra-Precision NMR Tubes, 5 Pack

• 3mm
• 200MHz 
• 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. 

Coaxial Inserts for NMR Sample Tube for Varian Spectrometers
4mm Quartz Tube W/60mm STEM. Includes one S-5-400-7 NMR tube to be used with the Coaxial Insert. 

60mm Stem OD is 3mm, Stem Sample Capacity is 210μL

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

Fluoropolymer Liner Tube Kits for 29Si and 11B

Includes:

• 2 O-Rings
• 1 Open-Ended 10mm 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.

5mm Valved NMR Tubes for Intermediate Pressure, 1 Pack

• 5mm
• 600MHz
• 7" (178mm)
• Thin 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).

5mm, Extreme Series Level 1, Valved NMR Tubes for Extreme Pressure, 1 Pack

• 5mm
• 600MHz
• 8" (203mm) NMR Tube
• Heavy Wall
• For High Pressure

Base Protection: Level 1 includes an additional standard fluoroelastomer o-ring seal to augment the existing fluoroelastomer o-ring, thus providing a secondary, backup o-ring if the primary one leaks or fails because of wear or physical damage.

The Extreme Series remains similar in function, use and pressure capability to the traditional High Pressure Valved NMR Sample Tubes, but the PTFE fluoropolymer valve plug has been upgraded and improved by changes to the design of the o-ring seal.  

The Extreme Series line consists of two categories: Level 1 and Level 3. Both levels incorporate a certain higher degree of valve seal integrity to guard against leakage or pressure loss due to o-ring failure caused by wear or other physical damage, and / or deterioration or damage caused by chemical exposure.

Standard Series™ High-Throughput NMR Tubes, 100 Pack

• 5mm
• High-Throughput
• 8 Inch (203mm)
• 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.
