Silicone Septum for 20 mm Vials

The white silicone stopper for injection vials is a closure component designed to ensure a secure and functional seal in laboratory containers. With a diameter of 13 mm, it adapts perfectly to standard glass vials with a 20 mm mouth, ensuring total compatibility with conventional storage and sampling systems.

Made of high-quality silicone, this element allows controlled penetration by hypodermic needles, facilitating the extraction or introduction of liquids without the need to remove the closure. This property is essential for maintaining sample integrity and minimizing the risk of external contamination during procedures.

When combined with an aluminum cap and applied using a pressure capper, it provides a completely hermetic seal, preventing losses, evaporation, and exposure to external agents. This configuration is widely used in chemical and pharmaceutical analysis and research environments.

The material exhibits excellent chemical resistance and maintains its mechanical properties after multiple punctures, allowing its use in applications that require repeated handling under controlled conditions.

This stopper constitutes a reliable solution for preserving the quality of samples and ensuring safety in laboratory processes where precise handling and protection against contaminants are critical factors.
