Achieve an airtight, resealable barrier for your air-sensitive chemistry. These premium Sleeve-Type Septum Stoppers feature a unique turn-over design that folds tightly over the outside of laboratory glassware necks. Engineered from high-elasticity, natural or synthetic rubber, they provide an exceptional moisture-proof and airtight seal. The self-healing pierceable septum allows for effortless syringe needle penetration and cannulation techniques while maintaining strict inert atmospheres.
Key Features
Dual-Seal Turn-Over Design: The sleeve folds securely down over the outside of the vessel neck. This dual-action sealing mechanism creates an extra barrier against air and moisture leaks, preventing accidental pull-outs.
Self-Healing Pierceable Septum: Made from premium elastomer with outstanding elasticity. It allows multiple syringe needle punctures during chemical sampling or transfers, resealing instantly to protect sensitive contents.Perfect Fit for Lab Glassware: Designed to fit standard ground glass joints, test tubes, flasks, and manifold ports. The flexible body stretches easily over glass lips without breaking fragile rims.
Reusable & Durable: Resists degradation from repeated stretching and punctures. It retains its sealing integrity over long-term storage and demanding lab procedures.
