Product Description

The Brown headspace lid with lid pad, designed for 20ml vials, features a durable closure system integrating a specialized Headspace vial lid pad. This 20ml vial closure pad ensures an airtight seal, compatible with standard autosamplers and analytical instruments operating at temperatures from -20°C to 150°C. Constructed with chemical-resistant PTFE/silicone material, it withstands aggressive solvents and maintains integrity under pressures up to 30 psi. Ideal for pharmaceutical, environmental, and food safety testing, its precision-molded design minimizes sample carryover. The lid's standardized 33mm diameter ensures compatibility with automation platforms. While optimized for single-use applications to prevent cross-contamination, its non-reusable nature may increase consumable costs in high-throughput labs. The integrated pad thickness (2mm) and uniform compression profile enhance reproducibility in GC/MS and HPLC headspace analysis.
