Product Description

The Brown graduated headspace lid with 4ml headspace lid pad is designed for precise sample volume measurement in gas chromatography applications. This headspace lid with graduated markings features a PTFE-coated, chemical-resistant aluminum body and silicone-lined rubber septa, compatible with standard 20mm vial necks. It operates within -20°C to 120°C temperature ranges and withstands pressures up to 30 psi. The brown graduation markings ensure visibility in low-light conditions, while the 4ml capacity pad enables accurate volatile compound analysis. Widely used in pharmaceutical, environmental, and food testing laboratories, its key advantages include leak-proof sealing and repeatable penetration durability, though limited to specific vial sizes. The clear 0.1ml increment markings enable precise residual space calculations during sample preparation.
