Laboratory glass test tubes are slender tubular containers widely used in laboratories such as chemistry, biology, and medicine, made of high-purity glass materials. They have become indispensable foundational tools in scientific research and experimental operations due to their unique physical and chemical properties. Glass test tubes have high transparency, allowing experimenters to clearly observe the color, precipitation, bubbles, and other details of the substance inside the test tube, thereby accurately judging the experimental process and results.

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.
