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.

Glass test tubes have become an indispensable tool in scientific experiments and industrial production due to their unique advantages and wide application fields. With their classic and reliable performance, glass test tubes still occupy an irreplaceable position. It should be noted that glass is fragile, so it should be handled with care during use to avoid severe collisions. In addition, for certain special experimental requirements, it may be necessary to use test tubes made of other materials instead of glass tubes.

According to different experimental requirements, there are various specifications and types of laboratory glass test tubes to choose from, such as ordinary test tubes, stoppered test tubes, centrifuge test tubes, etc. These different types of test tubes have different functions and uses to meet the needs of different experiments.

Due to the good stability of glass materials to most chemical substances, laboratory glass test tubes can safely carry various acid-base solutions, organic solvents, and biological samples without undergoing chemical reactions or corrosion. Laboratory glass test tubes can withstand high temperature environments and are suitable for experimental operations such as heating and distillation. During the heating process, the test tube should be uniformly heated to avoid local overheating leading to rupture. The glass surface is smooth and not easy to adhere dirt, so laboratory glass test tubes are easy to clean and reuse, meeting the strict cleanliness requirements of the laboratory.
