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.

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.
