Product features

Test tube with ground-in glass stopper is made of high-quality glass and has extremely high transparency, which allows the experimenter to clearly observe the state, color change, reaction process, precipitation, stratification and other phenomena of the substances in the test tube. This helps monitor the experimental progress in real time,detect and solve problems in time.

Test tube with ground-in glass stopper has good chemical stability, ensures the reliability of the experimental results. It has strong heat resistance,during the heating process, the glass test tube with ground-in glass stopper will not deform or break, ensures the smooth progress of the experiment.The special frosted glass stopper makes the connection between the test tube mouth and the stopper closer, effectively prevents the substances in the test tube from leaking, volatilizing or being contaminated by external impurities. Stopper test tubes are available in a variety of specifications and sizes, including different diameters, lengths and capacities, to meet the needs of complex experimental systems. It can be reused, which reduces the experimental cost and is also beneficial to the environment. The design of the test tube with stopper focuses on safety. The stopper is firmly connected to the mouth of the test tube and is not easy to loosen or fall off.

Test tube with ground-in glass stopper has a smooth surface, no burrs, no protrusions, fine craftsmanship, delicate and strong, beautiful and textured, uniform wall thickness, smooth and round, shiny and transparent, straight and slender, high transparency, fine frosting, good sealing.

Product applications

In chemical experiments:

Test tube with ground-in glass stopper can be used to store chemical reagents that are sensitive to air and moisture. For some reagents that need to be stored for a long time, stoppered test tubes are an ideal choice. Heating, cooling and other operations can be easily performed to meet the needs of different reaction conditions. In some separation and purification experiments, such as extraction, distillation etc, stoppered test tubes can be used as intermediate containers.

In biological experiments:

Test tube with ground-in glass stopper can be used to culture small amounts of microorganisms. Glass-stoppered test tubes can create suitable culture conditions by controlling the entry and exit of gases. In some cell culture experiments, it is used as a small-capacity culture vessel.

In the field of medical testing:

Used to store medical samples such as blood and urine. Sealed test tubes can prevent samples from external contamination and ensure the integrity and accuracy of samples. Convenient sample processing and testing. The sealing of stoppered test tubes can extend the storage time of samples.

In teaching experiments:

During the teaching process, teachers can use test tubes to demonstrate experiments, allow students to intuitively observe chemical and biological experimental phenomena. In experimental classes, students can use stoppered test tubes to perform various experimental operations. For example, experiments such as solution preparation, chemical reactions, and microbial culture are conducted to allow students to learn scientific knowledge in practice.
