Constricted Select Series NMR Sample Tubes, 1 Pack
5mm
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.)
Available with ULTRA-THIN wall NMR Tubes.

For Routine NMR
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.

Sample Vault™ Series NMR tubes with Sample Vault™ caps (U.S. Patent No. 8,054,080), are engineered for a new generation of high-throughput lab automation systems, including the Bruker SampleJet.
Our patented design incorporates a white band positioned on the NMR tube that aligns with the base of the cap, indicating a properly locked position. Together, our Sample Vault™ caps and Sample Vault™ tubes form an integrated closure system for fail-safe delivery of your sample into the magnet.
