Product Description

The Transparent screw lid with pad is a 20ml lab screw cap designed for precise headspace analysis, featuring an integrated sealing pad to ensure airtight containment. This headspace lid with sealing pad is compatible with standard 20ml vials, offering excellent chemical resistance and clarity for visual monitoring. Constructed from durable, inert materials, it operates within a temperature range of -20°C to 120°C and withstands pressures up to 50 psi. Ideal for GC/MS, environmental testing, and pharmaceutical industries, its transparent design allows easy inspection while maintaining sample integrity. Key advantages include leak-proof performance, reusable design, and compatibility with autoclaving. Limitations involve limited compatibility with highly aggressive solvents.
