Redesigned Fluoropolymer NMR Tube Caps
Redesigned tapered fluoropolymer closure system that works together with our fire-polished tube ends, offering superior sealing and sample integrity, preventing sample loss even during temperature gradients.
Standard Series™ High-Throughput NMR Tubes, 50 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.
Standard Series™ Economy NMR Tubes, 100 Pack
Standard Series™ Ultra-Precision NMR Tubes, 5 Pack
Economy NMR Tube Caps, 100 PackOur 10mm economy NMR tube caps are available in 4 different colors for better solvent labeling capabilities.
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.
Standard Series™ Precision NMR Tubes, 5 Pack
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.
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.
