Suprasil® NMR Tubes

Advantages of Suprasil®: ~ Suprasil® is high purity synthetic fused silica materials with outstanding optical characteristics in the deep UV to the near IR. The transmission rate from 190 nm to 2600 nm is well over 95% (10 mm thickness) excluding reflection. Ideal for photolysis experiments that employ 266 nm light from Q-Switched laser or 254 light emitted by Hg low pressure lamp with a Schott UG 5 filter.~ Possesses similar thermal expansion rate and tensile strength compared to natural quartz.Not recommended for EPR studies.

Application Notes

3 mm Economy Material Synthetic Quartz (commercial name Suprasil®) Impact on shimming quality by paramagnetic impurities1 None (<0.005 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 190 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.
