Quartz NMR Tubes

Advantages of Quartz: ~ Extremely low thermal expansion rate and high tensile strength. This feature makes quartz tubes 14 times more robust during cooling/heating process than corresponding Precision glass tubes.~ Naturally occurring quartz maintains over 85% transmission rate (10 mm thickness, with consideration of reflection loss) above 265 nm1.2, which makes quartz tubes preferable in photochemistry studies.~ Possesses a low Boron density as below 0.1 ppm, which guarantees a clean background in Boron-11 NMR studies.~ 2 times less dielectric constant than Pyrex® glass which helps improve the quality factor.Not recommended for EPR studies.

Application Notes

3 mm Economy Material Clear Fused Quartz (purified from naturally occuring quartz) Impact on shimming quality by paramagnetic impurities1 None (0.5 ppm Fe2O3) Rapid cooling/heating Yes, within 300 ˚C Max. working temperature 1300 ˚C Sample volume reproducibility2 0.5% Outer Diameter ± 0.0065 mm tolerance Cut-off wavelength 265 nm Compatible with Small Volume Insert Yes Recommended Application Experiments that require critical shimming quality Note 1: Impact on shimming quality varies upon magnetic field strength. Economy tube is recommended for 1D low field experiments. Note 2: Sample volume reproducibility refers to the maximum volume fluctuation when filling different NMR tubes to the same sample height. This number correlates to the reproducibility of time domain signal amplitude between different runs.
