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.

The surface of the glass test tube is smooth and not easy to adhere dirt, making it easy to clean and reuse, meeting the strict cleanliness requirements of the laboratory. Although glass is fragile, standardized use and storage methods can effectively reduce the risk of breakage. In addition, some specially designed test tubes, such as stoppered test tubes, can also prevent liquid splashing and improve experimental safety. Used for various chemical experiments such as solution preparation, reaction observation, and gas collection, it is a powerful assistant for chemists to explore material properties and verify chemical reaction laws.
