What this tube is for

A coaxial NMR tube holds two liquids in one tube without mixing them: a narrow inner tube sits in the centre of a 5 mm outer tube. Deutero makes it in two designs, both in Boro 3.3 borosilicate glass (ASTM type 1 class A).

Typical uses: a reference compound or a lock solvent goes in the inner tube and the sample in the outer tube. So nothing is added to the sample, and the sample can stay in its own solvent. Both liquids are measured together in one spectrum.

Your choices

Design: one-piece or two-part. In the one-piece tube (complete-5-3-7), a 3 mm inner tube is fused to the bottom of the 5 mm outer tube, so the two are always centred; the inner tube cannot be taken out. The two-part tube is a separate insert and a matching 5 mm outer tube: the insert is 4 mm wide at the top, fits exactly into the outer tube, and narrows to 2 mm towards the measuring region. You can take the insert out and clean the two parts separately.

Spectrometer, for the two-part tube: Bruker or Varian. The narrow lower part of the insert has a different length for Bruker and for Varian spectrometers. Choose coaxialb-5-7 for Bruker and coaxialv-5-7 for Varian (also Agilent) instruments.

Outer tube only. coaxial-5-7-ot is the 5 mm outer tube of the two-part design on its own, for example to replace a broken one.

Pack. Packs of 5.

The most common choice is coaxialb-5-7: the two-part tube for Bruker spectrometers.
