EPA/TOC 40 ml Borosilicate Pre-Cleaned Vial Kit with PP 24-414 Cap and PTFE/Silicone Septa

Complete kit for environmental sampling and total organic carbon (TOC) analysis. 40 ml clear borosilicate 6.8 vial, factory-assembled with cap and septa — ready to use, no pre-cleaning required. Pre-cleaning ensures purity levels appropriate for trace-level analysis in compliance with EPA standards.

Kit Components

• Vial: EPA/TOC type, clear borosilicate 6.8 glass, 40 ml
• Cap: White polypropylene (PP) screw cap, 24-414 thread
• Septa: 22 mm, natural PTFE and white silicone, 3.0 mm thick
• Dust cover: Included
• Supply condition: Factory-assembled, ready for immediate use

Applications

Designed specifically for water testing, volatile organic compound (VOC) analysis and any trace-level analytical determination where vial contamination can compromise results. Widely used in environmental laboratories, water quality control and forensic analysis.

The natural PTFE septa minimises sample interaction — critical when working at trace concentrations of organic compounds.

Why PTFE in the Septa

The PTFE layer in contact with the sample provides greater chemical resistance than silicone alone — no plasticiser leaching, no chromatographic interferences. The silicone outer face delivers the elasticity needed for a reliable seal around the injection needle.
