High borosilicate glass tubes have excellent high-temperature resistance and can maintain stable physical and chemical properties in high-temperature environments. It has a low coefficient of thermal expansion and can withstand significant temperature changes without being prone to cracking, with good resistance to thermal shock. Has good resistance to various acids, bases, and other chemical substances, and is not easily corroded. High borosilicate glass tubes have high light transmittance and can clearly observe the substances inside the tubes. Has high strength and hardness, and can withstand certain mechanical stresses.

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.

Due to the good stability of glass materials to most chemical substances, laboratory glass test tubes can safely carry various acid-base solutions, organic solvents, and biological samples without undergoing chemical reactions or corrosion. Laboratory glass test tubes can withstand high temperature environments and are suitable for experimental operations such as heating and distillation. During the heating process, the test tube should be uniformly heated to avoid local overheating leading to rupture. The glass surface is smooth and not easy to adhere dirt, so laboratory glass test tubes are easy to clean and reuse, meeting the strict cleanliness requirements of the laboratory.

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.

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.
