5mm Thin Wall Precision Quartz NMR Tubes
5 mm Thin Wall Precision Quartz NMR Sample Tube
Advantages of Quartz: ~ Extremely low thermal expansion rate and high tensile strength.
GROUP SKU : WILMAD-5MM-THINWALL-NMR-QUARTZTUBES
- 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.
- Impact on shimming quality varies upon magnetic field strength. Economy tube is recommended for 1D low field experiments.
- 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.
- Scientists rely on the expertise and artistic skills of Wilmad-LabGlass engineers and glass specialists to manufacture NMR and EPR consumables and laboratory glassware of the highest quality.
- Used daily in academia, healthcare and chemical, petroleum and other industrial applications, Wilmad offers 7000+ items as part of their standard catalog as well as custom fabrication for individual glassware, glass repair services and OEM glass parts.
