Factory Price Large or small borosilicate laboratory glass test tubes with cork

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.

Glass test tubes have become an indispensable tool in scientific experiments and industrial production due to their unique advantages and wide application fields. With their classic and reliable performance, glass test tubes still occupy an irreplaceable position. It should be noted that glass is fragile, so it should be handled with care during use to avoid severe collisions. In addition, for certain special experimental requirements, it may be necessary to use test tubes made of other materials instead of glass tubes.

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.

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.
