DURAN Wheaton Septa (W224163) Silicone

DURAN Wheaton Septa (W224163) Silicone

The DURAN Wheaton Septa (W224163) is a precision-molded silicone septum designed for unlined aluminum seals with a 20 mm outer diameter. It provides a tight, resealable, and chemically inert closure, maintaining sample integrity in analytical, pharmaceutical, and biotechnology environments.

The DURAN Wheaton Septa is constructed from high-purity medical-grade silicone that delivers outstanding elasticity and resistance to tearing, even after multiple needle punctures. It forms an airtight barrier, minimizing evaporation, contamination, and sample loss. This septum’s flexibility makes it suitable for repeated sampling, reagent dispensing, and long-term storage under controlled laboratory conditions.

Designed for compatibility and durability, it performs reliably under a wide temperature range and remains stable in contact with most common solvents and reagents.
