Solid, unperforated rubber stoppers are designed to provide a secure and adaptable seal in a wide variety of laboratory containers, such as flasks, graduated cylinders, test tubes, and other containers. Their structure allows for customized perforations according to the specific needs of each experimental setup, offering maximum versatility.
Manufactured in the European Union in accordance with DIN 12871 and ISO 4632/1 standards, they guarantee reliable performance and consistent quality in demanding work environments. The material exhibits good chemical resistance to non-oxidizing acids, alkalis, salts, and fats, as well as low gas permeability, which helps maintain system integrity.
These stoppers function stably in a temperature range between -50 °C and +90 °C, maintaining their mechanical properties under varying conditions. However, their performance is limited when exposed to aromatic hydrocarbons such as benzene, toluene, or xylene.
Their design allows for a firm fit in the neck of the container, providing an effective seal that reduces the risk of leaks or contamination. The possibility of machining through perforation makes them a practical solution for customized laboratory configurations.
Available in multiple dimensions, they adapt to different diameters and applications, covering a wide range of experimental needs.
A versatile, resistant, and functional solution for sealing systems in the laboratory, combining adaptability, security, and regulatory compliance in every use.
