ERO Polypropylene Cap

Description

Blue PTFE/White Silicone Septa with 9mm Blue Short Screw Polypropylene Cap – 5.5mm Centre Hole

Durable & Chemically Resistant Construction: This cap is made from high-quality polypropylene (PP), offering excellent durability and chemical resistance. The short-thread design (9mm) provides a secure and leak-proof fit for standard 9-425 vials, ensuring reliable performance even under demanding analytical conditions.

High-Performance Septa – PTFE/White Silicone: The cap includes a bonded septum composed of chemically inert blue PTFE on one side and high-purity white silicone on the other.

PTFE Layer: Provides excellent resistance to aggressive solvents, preventing sample contamination.

White Silicone Layer: Offers superior resealability and withstands multiple punctures, making it ideal for repeated sampling.

Optimal Center Hole Design: The 5.5mm center hole allows for easy and precise needle penetration, ensuring accurate and consistent sample injection while reducing the risk of coring and contamination.

Compatible with Standard Vials: Specifically designed for use with 9-425 screw neck vials (12x32mm), this cap and septa combination is compatible with most autosamplers, including those from Agilent, Waters, Thermo Scientific, and Varian.
