NMR Quartz Tubes, 5 mm, Wilmad, Precision
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 studiesInner surface is resistant to strong acid and base at ambient temperatureFor temperatures up to 1300˚C and variable temperature experiments that have a temperature step over 120˚CIncludes disposable caps

NMR Tube Rack, PP
Polypropylene rack with carrying handles features an upper deck with holes and a lower deck support for tube ends. Stackable. For 72 (6 x 12) tubes with 3 or 5mm diameter. Autoclavable.

NMR Tubes 5 mm, Wilmad, Economy
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.Made from borosilicate glass, ASTM E438 Type 1 Class B standardCamber and concentricity values listed are the Total Indicator Reading (TIR)Includes disposable caps
