Rubber stopper is also called rubber plug. Stoppers are generally made from natural rubber for durability and flexibility, but some are made of synthetic rubber for added resistance to chemicals such as reagents or solvents that would damage rubber. Rubber plugs come in various shapes and sizes to meet different operation requirements. They provide tight seal that helps prevent spills and evaporation. Some rubber plugs with one or two holes allow glass tubing to be inserted into the container through the plug. All the rubber stoppers are made to order.
