Catalog Number - 95025-14-2S

The 95025-14-2S BASIK Headspace Caps are a made‑to‑order configuration engineered for high‑temperature, pressurized headspace GC applications, combining silicone rubber / aluminum foil septa with a pressure‑relief aluminum crimp cap design.

These caps are fitted in 20 mm silver aluminum closures with an 8 mm center hole and engineered scoring, providing enhanced sealing surface area, consistent autosampler access, and controlled venting for safety in demanding analytical environments.

✅ Recommended for validated, high‑temperature and safety‑critical workflows

• Pressure Relief Caps with Silicone/Foil Septa

Pressure Relief Design – Engineered Safety

• Scored aluminum caps designed to vent at ~3.0 ± 0.5 bar

• Helps prevent:

  • Vial rupture

  • Excess pressure buildup

• Protects:

  • Operators

  • Instruments
