DURAN Plastic Stopper NS 29/32

DURAN Plastic Stopper NS 29/32

The DURAN Plastic Stopper NS 29/32 (Catalog No. 292050904) ensures secure, reusable, and color-coded sealing for DURAN volumetric flasks and compatible laboratory glassware. It is produced from high-quality polyethylene (PE), a flexible and chemically resistant polymer designed for long-term laboratory performance. Moreover, the precisely molded joint provides a perfect fit, preventing leaks and protecting sensitive samples from contamination.

The color-coded design allows easy identification of stopper sizes, improving efficiency and accuracy during laboratory operations. In addition, its smooth, low-friction surface allows effortless insertion and removal without scratching the glass joint. Therefore, this stopper combines ergonomic handling, safety, and durability for professional laboratory use.

Because polyethylene is chemically inert, lightweight, and shatterproof, the stopper maintains excellent sealing reliability even after repeated use. Consequently, it serves as a durable and cost-effective alternative to traditional glass stoppers. Overall, the DURAN Plastic Stopper NS 29/32 offers robust sealing, chemical protection, and user convenience for modern laboratory environments.
