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 percentage 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.
