Product Description

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.



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 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.



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.



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.
