Product Description

The medium boron sample vials are designed with specialized graduated headspace caps (2ml) for precise volume measurement in gas chromatography and mass spectrometry applications. The borosilicate glass vials feature a unique zona pellucida vial lid design, ensuring optimal transparency for visual inspection while maintaining chemical resistance up to 130°C. Each lid incorporates a PTFE-faced silicone septum and integrates with standard autosampler systems via 13mm threading. The graduated markings on the caps allow 0.1ml resolution for accurate headspace analysis, compatible with temperatures ranging from -80°C to 200°C. Widely used in pharmaceutical stability testing, environmental monitoring, and forensic toxicology, these vials provide excellent thermal shock resistance and minimal sample adsorption. Key advantages include enhanced leak-proof performance at 35psi internal pressure, though they require manual alignment for proper graduation visibility. The matching lid pad securely seals low-volume samples while preventing cross-contamination in high-throughput laboratory workflows.
