NMR tubes

NMR tubes are available, according to requirement, in three accuracy classes. The correct tube can be selected depending on magnetic field and spin. The tubes are noteworthy for their close tolerances and accuracy, especially to their straightness, wall thickness and wall thickness distribution. Consequently, quick and accurate test results are achievable.

Type Economic:
The disposable for economical use in fully automatic sample dispensers or where high throughputs are involved.

• Applicable until 300 MHz

Type Professional:
For professional use in industry and research in the medium and high resolution area of NMR spectroscopy.

• Applicable until 400 MHz

Type Scientific:
For scientific use with high value samples and optimum substance exploitation in the highest resolution range of NMR spectroscopy.

• Applicable until 500 MHz

These EPR tubes are manufactured from upmarket quartz glass with only slightest amounts of paramagnetic trace elements. The tubes are delivered single packed and sealed in plastic foil.

These NMR tubes were developed with the special length of exactly 100 mm and are thus specifically adjusted for the Bruker MATCH^™ system.

The High Precision NMR tubes are manufactured with high accuracy and excellent straightness and concentricity. They are particularly suitable for quantitative measurements and measurements in spectrometers with high measurement frequencies above 600 MHz up to the highest available field strengths above 1 GHz. The tubes are made of borosilicate glass 3.3, which complies with USP Type I and ASTM E438, Type I, Class A requirements. NMR tubes are supplied without caps, please order caps separately.
