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.
Select Series™ 3mm, High-Throughput NMR Tubes, 25 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.
Select Series™ 3mm, Ultra-Precision NMR Tubes, 5 Pack
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.
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.
Screw-Cap NMR Sample Tubes, 1 Pack Screw-Cap Septum NMR Tubes offer both convenience of a screw cap and that of a septum where material can be removed. Convenient screw-cap access with the security of a fluoropolymer (PTFE) seal. Supplied with open top cap & fluoropolymer/silicone septum for quick and clean access with a 22 gauge standard point needle.
5mm, Standard, Natural Quartz EPR Sample Tubes, 5 PackNorell EPR tubes produce lower background signals and have better resistance to breakage than competitor brands. Our proprietary technical treatment reduces background noise along with the benefit of protecting against tube breakage.
Additionally, we have designed a new fluoropolymer closure system around our fire-polished tube ends that prevents sample loss during temperature gradients. Available in both standard and ultra precision. Supplied with tapered fluoropolymer caps.
Solid Screw-Cap NMR Tube Cap without Septum, 12 PackCompatible with 5mm or 10mm Screw-Cap NMR Sample Tubes.
Select Series™ 5mm, Ultra-Precision NMR Tubes, 5 Pack
Medium Wall NMR Sample Tubes, 5 Pack
Medium wall (0.8 mm) NMR tubes offer a considerable increase in the margin of safety against breakage while keeping 65% of the sample volume. Can be used for student use or in auto-sampling systems. Available either constricted and/or amberized.
