Constricted Select Series NMR Sample Tubes, 1 Pack - 5mm
- 8" (203mm)
- 800MHz
- 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.) Available with ULTRA-THIN wall NMR Tubes. Pictured with optional NorLoc™ Cap. Constricted NMR tubes ship with economy caps.

5mm Valved NMR Tubes for Intermediate Pressure, 1 Pack - 5mm
- 600MHz
- 7" (178mm)
- Medium Wall
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). |
