Inverted Solid Silicon Rubber Stopper For Laboratory
Inverted rubber stoppers are used to seal various experimental instruments and containers. Their inverted design allows them to fit tightly around the bottle mouth, effectively preventing the leakage of gases and liquids and ensuring the accuracy and safety of experiments. Moreover, they facilitate the insertion of tools like injection needles. When reagents need to be added or samples taken, there's no need to remove the stopper, which reduces the risk of contamination and improves operational efficiency.
