Plastic stoppers include various models designed to seal beakers, Erlenmeyer flasks, bottles, test tubes, and other laboratory containers used in preparation, storage, or analytical operations. Manufactured from technical polymers resistant to chemical agents and, depending on the variant, to moderate temperatures, they provide reliable tightness, dimensional stability, and durability suitable for repeated handling. Controlled tolerances ensure proper compatibility with standardized laboratory vessel diameters. Some models may be autoclavable or compliant with ISO or DIN specifications, depending on protocol requirements. A complete range is available to meet the needs of research, quality control, and the chemical, cosmetic, and food industries.
