Constricted Select Series NMR Sample Tubes, 1 Pack - 3mm
- 8" (203mm)
- 500MHz
- I.D. at Constriction: 1.5mm - 2.0mm
- 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 heat source (e.g. a small butane torch) then gently twist and pull on the open end to seal. Also allows samples to be stored under vacuum or inert gas. (Please note: constricted tubes are specified and ordered by the required finished length and are measured from the tube bottom to the center of the constriction.) Pictured with optional NorLoc™ Cap. Constricted NMR tubes ship with economy caps.

Secure Series™ NMR Tubes 5 Pack - 3mm
- 500MHz
- 8 Inch (203mm)
- Includes “Norloc™ with Security Band” Caps
- A patented proprietary surface treatment with a unique textured surface ensures precise and positive retention in Bruker, Agilent/Varian, and Jeol spinner turbines.
The Secure 33 Series™ NMR tubes are made from ASTM Type I Class A borosilicate glass ("low expansion" borosilicate glass such as Corning Pyrex® 7740 or equivalent) and match the properties of the Select 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™ 3mm, Ultra-Precision NMR Tubes, 5 Pack - 3mm
- 800MHz
- 7 Inch (178mm)
- Ships with Economy Cap. NorLoc™ Caps Sold Separately.
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. |

Norell Tube Carrier - WHITE X 3 |
|
Introducing the new biopolymer tube carrier from Norell®. Manufactured from laboratory engineered high strength & high modulus biopolymer. This durable container protects both personnel and glass NMR tubes during temporary storage and transport, shielding against breakage and loss of sample that might otherwise result if the sample tube is accidentally dropped, rolls off of the lab bench or encounters other similar mishaps.
The carrier holds one 5mm diameter x 7 inches long NMR tube, with ample space for the cap, including standard NMR tube caps, NorLoc™ caps, and fluoropolymer NMR tube caps. The snap-on cap fits tightly and does not dislodge easily if struck or dropped, adding the final measure of protection to precious or hazardous samples. |
