9 mm Screw Top Caps for 9-425 GC Vials – PTFE/Red Silicone Septa, Autosampler Compatible General Lab Supplies Polyethylene pipettes will not shatterDescription In gas chromatography (GC) and autosampler based analytical workflows, sample integrity is highly dependent on reliable vial sealing. Volatile compounds, solvent evaporation, and septa failure can introduce variability and compromise analytical accuracy during injection sequences. High throughput laboratories require consistent, chemically resistant sealing systems that maintain sample stability throughout storage and automated injection.
