DURAN Plastic Stopper NS 19/26 292040706

DURAN Plastic Stopper NS 19/26 292040706

The DURAN Plastic Stopper NS 19/26 (Catalog No. 292040706) provides secure, reusable, and chemical-resistant sealing for DURAN volumetric flasks and compatible laboratory glassware. It is made from premium-quality polyethylene (PE), which ensures durability, flexibility, and outstanding resistance to most laboratory reagents and solvents. Moreover, its precision-molded design guarantees an accurate fit for standard-taper joints, reducing the risk of leakage or contamination.

The smooth and polished surface allows easy insertion and removal without damaging glass joints, extending the lifespan of both stopper and flask. In addition, its lightweight, shatterproof construction offers a safe and practical alternative to traditional glass stoppers. Therefore, it provides both efficiency and safety during routine laboratory use.

Because polyethylene is chemically inert, non-reactive, and moisture-resistant, this stopper maintains its performance and sealing strength even after repeated use. Consequently, it offers consistent, long-term reliability for laboratories that require precision and durability. Overall, the DURAN Plastic Stopper NS 19/26 combines robust construction, secure closure, and ease of use for professional laboratory environments.
