Product introduction
Silicone rubber stopper for test tube is an accessory used to seal test tubes. They are made of silicone material and are generally cylindrical. Their size and shape match the common test tube openings. There are different specifications to accommodate test tubes of various calibers. Some silicone plugs have a small hole in the center to facilitate the insertion of experimental equipment such as thermometers and stirring rods, so that temperature measurement or stirring operations can be performed in a sealed state.
Product features
(1) Tight seal: good elasticity, fits tightly with the test tube mouth, prevents leakage and external pollution.
(2) Stable properties: resistant to chemical corrosion, not easy to react with a variety of substances, ensuring experimental accuracy.
(3) Strong temperature resistance: can withstand certain high and low temperatures, adapt to different experimental temperature requirements.
(4) Safe and non-toxic: meets safety standards and is suitable for biological, food and other related experiments.
(5) Diverse designs: with or without holes to meet the needs of different experimental operations.

Product applications
Silicone rubber stopper for test tube can be used to seal and preserve volatile and reactive reagents in chemical experiments to prevent them from deteriorating; in biological experiments, they can create a sterile environment for cell culture, microbial culture, etc. to avoid contamination by foreign bacteria; they can also be used in the field of analysis and testing to ensure that samples are not disturbed by external factors during the processing process, thereby ensuring the accuracy of the analysis results.
