The 5 mm is the outer diameter of the tube (4.95 mm), the size that most NMR probes take. The length is given separately: 7 inches is 178 mm, 8 inches 203 mm.

Concentricity tells how even the wall is all round; camber tells how straight the tube is. Both get smaller as the grade goes up, from 7 and 25 µm at 300 MHz to 3 and 3 µm at 800 MHz. Choose the grade of your spectrometer, or a higher one.
