Clear quartz glass tube can operate stably at temperatures up to 300 degrees and can withstand short-term temperatures of approximately 350 degrees, demonstrating excellent heat resistance. Except for hydrochloric acid, the glass tube shows high chemical inertness to most acidic substances. Especially at high temperatures, its chemical stability far exceeds that of other engineering materials, ensuring long-term reliability in use. 

Thanks to its extremely low coefficient of thermal expansion, high-precision glass tubes can withstand rapid temperature fluctuations without damage. Even if heated to 300 degrees and then quickly placed in cold water, they remain structurally intact with no risk of cracking. In terms of appearance, high-precision glass tubes are made of high-transparency glass material, free of impurities and bubbles, with a smooth surface and a flat tube opening, ensuring excellent light transmission and clear visual effects. 

Clear quartz glass tubes have a very high resistance value and are ideal insulating materials for electricity. Even in high-temperature environments, their electrical performance remains stable, meeting the requirements of various electrical applications.
