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.

High quality glass test tubes have extremely high transparency, which can clearly display the color, precipitation, bubbles and other details of the substances inside the tubes, providing great convenience for experimental observation. Glass material has good stability to most chemical substances, is not easily corroded, and can safely store and react with various acid and alkali solutions and organic solvents. Glass test tubes can withstand high temperature changes and are suitable for experimental operations such as heating and cooling, such as distillation and burning.
