DURAN Plastic Stopper NS 29/32 292040903

The DURAN Plastic Stopper NS 29/32 (Catalog No. 292040903) delivers reliable, reusable, and chemical-resistant sealing for DURAN volumetric flasks and other standard laboratory glassware. It is manufactured from high-quality polyethylene (PE), providing excellent flexibility, toughness, and resistance to common laboratory chemicals. Moreover, its precision-molded taper ensures a perfect fit, effectively preventing leakage, contamination, or evaporation during use.

The smooth surface enables effortless insertion and removal without scratching the glass joint, extending the life of the equipment. In addition, the stopper’s lightweight, unbreakable design offers a safe and practical alternative to traditional glass stoppers. Therefore, it provides both efficiency and safety for everyday laboratory operations.

Because polyethylene is chemically inert, non-absorptive, and moisture-resistant, the stopper maintains its sealing integrity after repeated use. Consequently, it offers consistent performance and long-term reliability in analytical, chemical, and educational laboratories. Overall, the DURAN Plastic Stopper NS 29/32 combines durability, precision, and ease of handling for professional laboratory environments.
