Product Description

The 10-425 (ND10) closure system is engineered to provide a superior seal for vials with 10mm thread finishes. Unlike standard 8mm caps, the ND10 series offers a more substantial grip and a wider center hole, making it the preferred choice for high-throughput labs using Jasco and Waters autosamplers.

Our septa are manufactured from high-purity Silicone and PTFE, bonded without adhesives to ensure zero contamination. The 1.5mm thickness provides the perfect balance between ease of needle penetration and effective resealing after multiple injections.

Product Feature

Precision-molded closures designed for consistency and sample safety.

7mm Center Hole: Reduces the risk of needle bending and extends the life of expensive autosampler needles.

Medical Grade PP: Our caps are made from virgin polypropylene to avoid leaching of plasticizers into the sample.

Chemical Resistance: The PTFE liner offers universal resistance to organic solvents, acids, and bases.

Vacuum-Tight Seal: Specifically designed to minimize evaporation of volatile solvents during long run times.

Pre-assembled Design: SNC series caps come with septa pre-installed, reducing lab preparation time and handling contamination.
