DURAN Plastic Stopper NS 14/23 292040603

DURAN Plastic Stopper NS 14/23 292040603

The DURAN Plastic Stopper NS 14/23 (Catalog No. 292040603) provides secure, reusable, and chemically resistant sealing for DURAN volumetric flasks and other compatible glassware. It is made from high-quality polyethylene (PE), a flexible and durable polymer known for its resistance to laboratory chemicals and solvents. Moreover, the stopper’s precision-molded taper ensures a perfect fit that prevents leaks, contamination, and evaporation.

The smooth surface finish enables effortless insertion and removal without damaging the glass joint, ensuring a long service life. In addition, the stopper’s lightweight and unbreakable design make it safe and convenient for frequent use in laboratories. Therefore, it offers a reliable and practical closure solution for routine volumetric and analytical applications.

Because polyethylene is chemically inert, non-absorptive, and moisture-resistant, the stopper maintains consistent sealing performance even after repeated use. Consequently, it serves as a long-lasting, cost-effective alternative to traditional glass stoppers. Overall, the DURAN Plastic Stopper NS 14/23 delivers durability, precision, and safety for professional laboratory environments.
