Fluoropolymer NMR Tube Liners
For NMR studies where chemical compounds such as hydrofluoric acid, ammonium bifluoride and concentrated hydroxide solutions are present. Our fluoropolymer tube liners have a thin-wall construction that minimizes filling-factor losses. Supplied with a PTFE plug closure.
Thin-Wall Transparent Fluoropolymer FEP Tubing
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.
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.
Economy NMR Tube Caps, 100 PackOur economy NMR tube caps are now available in 12 different colors for better solvent labeling capabilities.
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).
The NORELL® NorLoc™ Generation II Security Cap™
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.
Secure Series™ NMR Tubes 25 Pack
The Secure 55 Series™ NMR tubes are made from ASTM Type I Class B borosilicate glass ("high expansion" borosilicate glass such as Kimble N-51A or equivalent) and parallel the properties of the Standard Series™ NMR tubes from Norell®
Secure Series™ NMR tubes feature several patented design elements that add a superior level of sample containment and isolation, safeguarding the integrity of precious or critical NMR samples and assuring secure retention of the NMR tube in the spinner turbine.
Secure Series™ NMR Tubes ship with our patented NorLoc Caps™ featuring a Security Band™ that engages and locks into the NorLoc II Security Cap™, securely joining the cap to the NMR tube.
Select Series™ 5mm, Ultra-Precision NMR Tubes, 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.
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.
