Factory Direct Selling Large or small borosilicate laboratory glass test tubes with cork

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.

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.
