Intermediate and High Pressure Valved NMR Tubes - Intermediate Pressure Valved NMR Tubes, High Pressure Valved NMR Tubes, Extreme Series High Pressure Valved NMR Sample Tubes
Secure Series - The Secure Series™ NMR tubes feature several Patent Pending 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.
Select Series NMR Tubes - The “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
Standard Series NMR Tubes - “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.
Special Purpose NMR Tubes:
Constricted Select Series™ for High Resolution NMR - Constricted NMR tubes offer a convenient way to seal your sample from air or other contaminants. Simply heat the constricted portion using a suitable source, and gently twist and pull on the open end to seal. Also allows samples to be stored under vacuum or inert gas.
Constricted Standard Series™ for Routine NMR - Constricted NMR tubes offer a convenient way to seal your sample from air or other contaminants. Simply heat the constricted portion using a suitable source, and gently twist and pull on the open end to seal. Also allows samples to be stored under vacuum or inert gas.
Amberized Select Series™ for High-Resolution NMR - Amberized NMR tubes offer photosensitive materials protection from visible and ultraviolet radiation. Typical absorbance (ABS) is between 0.5 and 1.0 from 650 to 300 nm and is greater than 1.0 from 300 to 190 nm.
Amberized Standard Series™ for Routine NMR - Amberized NMR tubes offer photosensitive materials protection from visible and ultraviolet radiation. Typical absorbance (ABS) is between 0.5 and 1.0 from 650 to 300 nm and is greater than 1.0 from 300 to 190 nm.
Bruker Microbore NMR Sample Tube - New ultra-precision NMR tube for Bruker's microprobes, offers complete reliability and reproducibility over other brands. Features a tapered lower stem mounted on a high precision 800 MHz rated 5mm Select Series™ NMR tube that performs perfectly even under severe temperature gradients. Data integrity is completely assured thanks to our high quality manufacturing standards.
Heavy Wall NMR Sample Tubes - Heavy wall (1.4 mm) NMR tubes offer the ultimate protection from breakage, either through rapid changes in temperature or pressure, or from mishandling. Recommended for use with hazardous or radioactive samples, where sample containment is critical. Available either constricted and/or amberized.
Medium Wall NMR Sample Tubes - Medium wall (0.8 mm) NMR tubes offer added protection from breakage while keeping 94% of the sample volume. Can be used for student use or in auto-sampling systems. Available either constricted and/or amberized.
High-Throughput NMR Sample Tubes - NEW 4mm and 4.25mm sizes. Recommended for use with our 5mm spinner turbine inserts. Ideal for reducing salt effects when running buffered solutions for bio-samples. Only Norell can satisfy the many customer requests for a High-Throughput NMR tube that features both high-precision, as required in today’s high-field spectrometers, and economy in price. Made from ASTM Type 1 borosilicate glass for reproducibility and durability. Specially designed for onetime use for routine NMR, our high-precision NMR tubes will out-perform more expensive competitor brands. See for yourself. Available in packs of 25.
5mm Suprasil Quartz NMR Sample Tubes - Recommended for Boron NMR [<0.01 ppm Boron] and/or UV catalyzed reactions in the region above 190nm [90%T @ 190nm].
Select Series NMR Sample Tubes for Ceramic Turbines - Ceramic spinner turbines, often relied upon for variable or high temperature applications, are manufactured to extremely precise dimensional specifications. To meet this stringent diameter requirement, Norell has developed a new 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.
Sample Vault NMR Tubes - An Integrated Closure System. The Sample Vault Series™ NMR tubes with Sample Vault™ caps (U.S. Patent No. 8,054,080) are engineered for the new generation of high-throughput lab automation systems, including Bruker SampleJet™. Designed for use with 96 position carriers using 103.5 mm (about 4”) long NMR tubes with open port caps, or 178 mm long NMR tubes with closed port caps. Sample Vault™ caps have superior holding and sealing capabilities which eliminate cap/tube failure in your instrument.
Quartz NMR Tubes - Recommended for Boron NMR [< 0.1 ppm Boron] and/or UV catalyzed reactions in the region above 210nm [90%T @ 210nm]. Medium and heavy wall NMR tubes are now available, in addition to standard, thin wall NMR tubes.
EPR Tubes - Norell EPR tubes produce lower background signals and have better resistance to breakage than competitor brands. Our proprietary technical treatment process 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.
