JG Finneran Associates PTFE/Silicone Preassembled Screw Caps

JG Finneran Associates PTFE/Silicone Preassembled Screw Caps

Description

JG Finneran Associates PTFE/Silicone Preassembled Screw Caps are designed for sealing chromatography vials to ensure sample integrity during storage and analysis. These caps provide a secure, leak-resistant seal for laboratory vials, facilitating reliable sample handling in automated and manual workflows. By combining the chemical resistance of PTFE with the resealability of silicone, they protect sensitive samples from contamination and evaporation.

Key Features

• Preassembled design reduces handling time and the risk of liner contamination during preparation.
• Dual-layer septa construction provides a chemical barrier alongside excellent resealing properties.
• Compatible with standard screw-thread vials used in high-performance liquid chromatography (HPLC) and gas chromatography (GC).
• Engineered for consistent performance with robotic autosamplers and high-throughput laboratory systems.

Applications

• Sample preparation and containment for HPLC and GC analysis.
• Secure storage of volatile organic compounds and sensitive chemical reagents.
• Automated sampling workflows in analytical chemistry and pharmaceutical research.

Specifications

• Septa Material: PTFE and Silicone
• Closure Type: Screw Thread
• Assembly: Pre-inserted liner

Disclaimer

Users should verify chemical compatibility between the PTFE/Silicone liner and specific solvents or aggressive chemicals before use.
