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. With retrace code. Please order closing caps separately.
For professional use in industry and research in the medium and high resolution area of NMR spectroscopy.

The thin-walled high-throughput Wilmad^® NMR tubes have an average camber of 60 microns to guarantee the clarity of the spectrum for small molecule (MW <250) samples up to 600 MHz. Designed for routine use in most low to mid field NMR spectrometers.

• Made from borosilicate glass, ASTM E438 Type 1 Class B standard
• Camber and concentricity values listed are the Total Indicator Reading (TIR)
• Includes disposable caps
• WG-1000-7-SJ is supplied with authentic Bruker SampleJet cap

The NMR tubes are produced with high precision. They are suitable for routine measurements, high-throughput measurements or NMR systems with autosampler at measurement frequencies up to 600 MHz. The tubes are manufactured from borosilicate glass 3.3 which is conform to USP Type I and ASTM E438, Type I, Class A. Please order closing caps separately.

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.

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

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 tubes coloured by silver ion diffusion are particularly suitable for handling UV-sensitive substances. The tubes are manufactured from borosilicate glass 3.3 which is conform to USP Type I and ASTM E438, Type I, Class A. They are supplied with a green cap.

Our KIMAX^®-HQ NMR tubes are our highest quality NMR tubes and are 100% gauged for wall thickness, concentricity and camber specifications.

Thin-walled Precision Quartz NMR tubes. To maximize Signal-Noise-Ratio, Precision NMR Tubes have minimal paramagnetic impurities that would impact shimming. The Quartz tubes have an extremely low thermal expansion rate and high tensile strength which is 14 times more robust during the cooling/heating process than Type 1 Class A glass tubes.

• Low Boron density at or below 0.1 ppm guarantees a clean background in Boron-11 NMR studies
• Inner surface is resistant to strong acid and base at ambient temperature
• For temperatures up to 1300˚C and variable temperature experiments that have a temperature step over 120˚C
• Includes disposable caps

The thin walled Wilmad Economy NMR tubes are designed for routine use in all NMR spectrometers. They fit tightly in any spinner turbine and have zero NMR background. For experiments with small organic molecules (Molecular Weight ~500) at ambient temperatures. Cooling/heating of these tubes may lead to breakage.
