Kontes® NMR tubes

Kontes® has provided superior quality products for the nuclear magnetic resonance spectroscopy market since 1968. Kontes NMR tubes are manufactured from Kimax® ASTM Type I borosilicate glasses and their performance is assured by state of the art manufacturing and inspection processes for wall thickness, concentricity, and camber. Wall thickness is closely monitored to assure that our customers consistently get reproducible results. Nonconformity to concentricity tolerances causes portions of the sample to be exposed to differences in the magnetic field leading to undesirable modulation sidebands. Camber is the measure of straightness of a tube and is determined with gauges by measuring the deflection at the middle of a rotating tube held at the ends. Recorded as Total Indicator Reading (T.I.R. or the absolute value of the deflection range), tubes with deviations <0.002” (0.051mm) in camber can be expected to spin reliably. Higher frequency NMR spectrometers require stricter tolerances for the camber of tubes. Kontes guarantees their tubes to meet stated dimensional specifications and to produce accurate results according to the field strength of the NMR spectrometer.
