Standard Series™ High-Throughput NMR Tubes, 100 Pack
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.
Long Tip Pasteur Pipette
Suprasil® Quartz NMR Sample Tubes, 1 Pack
Recommended for Boron NMR [< 0.01 ppm Boron] and/or UV catalyzed reactions in the region above 190nm [90%T @ 190nm].
Optimizer Inserts™ for 5mm Spinner Turbines
Precision adapter, made from a proprietary formulation of acetal homopolymer resin, holds 1.5mm, 1.7mm, 2.0mm, 2.5mm, 3mm, 4mm or 4.25mm NMR tubes in 5mm spinner turbine. Available for Agilent/Varian, Bruker & JEOL spectrometers. Does not include spinner turbine.
Fluoropolymer Liner Tube Kits for 29Si and 11B
Includes:
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.
Amberized Standard Series NMR Sample Tubes, 1 Pack
Available with ULTRA-THIN wall NMR Tubes.
Pictured with optional NorLoc™ Cap. Amberized NMR tubes ship with economy caps.
5mm Valved NMR Tubes for Intermediate Pressure, 1 Pack
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).
Select Series™ 5mm NMR Sample Tubes for Ceramic Turbines, 5 Pack
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.
When working under variable temperature conditions, the tube diameter specifications narrow and tighten even more to take account of any slight thermal expansions or contractions in the ceramic turbine.
To meet this stringent diameter requirement, Norell has developed a line of NMR sample tubes, including both 5mm and 3mm O.D. sizes, that adhere to strict outside diameter specifications that are very tightly controlled.
5mm, Extreme Series Level 1, Valved NMR Tubes for Extreme Pressure, 1 Pack
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.
