DURAN Wheaton Rubber Stopper (W224100-202)

The DURAN Wheaton Rubber Stopper (W224100-202) is a 3-leg lyophilization stopper made from high-quality gray rubber, specifically designed for freeze-drying (lyophilization) processes in pharmaceutical, analytical, and research laboratories.

Its three-leg design provides enhanced stability and uniform support within the vial neck, maintaining proper alignment during vacuum drying and heat treatment. The stopper’s gray rubber composition ensures superior chemical resistance, low gas permeability, and excellent elasticity, minimizing contamination risks and preserving sample integrity.

Fully autoclavable, the stopper retains its shape and sealing performance even after multiple sterilization cycles, making it ideal for aseptic environments and sterile packaging operations.

The DURAN Wheaton Rubber Stopper guarantees consistent sealing, mechanical durability, and reliable performance in critical laboratory and pharmaceutical applications.
