The importance of glass test tubes, as indispensable laboratory basic tools in many fields such as chemistry, biology, and medicine, is self-evident. They play a crucial role in scientific research, educational experiments, and industrial production due to their unique physical and chemical properties.

A glass test tube is a slender tubular container made of high-purity glass material. They usually have a transparent appearance, making it easy to observe changes in the state of liquids or solids inside the tube. At the same time, they have good corrosion resistance and high temperature resistance, and can safely carry various chemical reagents and biological samples. According to different experimental requirements, glass test tubes can be divided into various specifications and types, such as ordinary test tubes, stoppered test tubes, centrifuge test tubes, etc.
