Product Description

The chromatography headspace cap is designed for secure sealing of 4ml headspace injection vials, ensuring airtight compatibility with autosamplers and GC systems. It integrates a precision-engineered 4ml vial septa made of high-purity PTFE/silicone laminate, optimized for temperatures ranging from -40°C to 250°C and pressures up to 15 psi. Ideal for volatile compound analysis in pharmaceutical, environmental, and food testing industries, this cap minimizes sample evaporation and cross-contamination. Its chemically inert construction resists solvents and acids, while the pre-slit design ensures smooth needle penetration. The component suits standard 20mm vial necks and complies with ISO 9001-certified workflows. Primary advantages include reliable seal integrity and reusability, though septa may require periodic replacement after repeated punctures.
