High borosilicate glass tubes have excellent high-temperature resistance and can maintain stable physical and chemical properties in high-temperature environments. It has a low coefficient of thermal expansion and can withstand significant temperature changes without being prone to cracking, with good resistance to thermal shock. Has good resistance to various acids, bases, and other chemical substances, and is not easily corroded. High borosilicate glass tubes have high light transmittance and can clearly observe the substances inside the tubes. Has high strength and hardness, and can withstand certain mechanical stresses.
