Cork to fit boiling tube cork stopper, Nairobi Industrial Area

A cork stopper for a boiling tube is a cylindrical piece made from natural cork material, designed to fit snugly into the opening of a boiling tube. Its primary function is to seal the tube, preventing the escape of gases or liquids during heating or reactions. The stopper is typically slightly larger than the tube's opening, allowing for a secure fit without slipping, while also being able to withstand moderate temperatures. This cork material is flexible and provides a tight seal, making it ideal for laboratory experiments involving heating or containment.
