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.

In biological research, glass test tubes are commonly used in experiments such as cell culture, microbial culture, and enzymatic reactions, providing an important experimental platform for the development of life sciences.

In the pharmaceutical industry, glass test tubes are used in drug synthesis, drug analysis, drug stability testing, and other processes to ensure the quality and safety of drugs.

In the teaching of disciplines such as chemistry and biology, glass test tubes are indispensable teaching aids that help students intuitively understand theoretical knowledge and cultivate experimental skills.
