Product Description

The Chromatography injection vial headspace cap (60ml) is designed for secure sealing of headspace vials in gas chromatography applications. This headspace closure 60ml features a PTFE-lined silicone septum, ensuring chemical resistance against acids, bases, and organic solvents within a temperature range of -40°C to +120°C. Compatible with 60ml injection vial seals, it provides hermetic sealing with a torque range of 8-12 in-lb, minimizing sample evaporation and volatile compound loss. The cap's standardized 20mm diameter and 18mm height ensure compatibility with autosamplers and thermal desorption systems. Widely used in pharmaceutical, environmental, and food testing labs, these chromatography headspace vial caps excel in trace analysis due to low background interference. While offering exceptional inertness, they require periodic septum replacement after multiple injections. The design supports direct integration with automated sampling interfaces and maintains consistent pressure integrity during heated headspace extraction cycles.
