Catalog Number - 95025-01-2S

The 95025-01-2S MICROSOLV Headspace Caps are designed for safe and reliable headspace GC analysis, featuring dark grey butyl rubber septa combined with pressure‑relief aluminum caps.

These caps incorporate scored, clear‑lacquered aluminum closures that are engineered to vent at controlled pressure levels, improving laboratory safety when working with volatile or pressurized samples.

Pressure Relief Cap Design – Enhanced Safety

• Aluminum caps with engineered score lines

• Designed to vent at ~3.0 ± 0.5 bar

• Helps:

  • Prevent vial rupture

  • Reduce risk during high‑pressure conditions

✅ Ideal for headspace applications involving pressurization or volatile compounds

Butyl Rubber Septa – PTFE‑Free Compatibility

• Dark grey molded butyl rubber septa (no PTFE)

• Eliminates:

  • PTFE contamination

  • PTFE interference

✅ Recommended when:

• PTFE is an analyte

• PTFE must be avoided

Reliable Sealing for Routine Analysis

• Septa hardness: 55° Shore A

• Thickness: 3.0 mm

• Provides:

  • Good sealing integrity

  • Durable performance in standard use

✅ Suitable for routine and non‑critical workflows

Temperature Compatibility – Headspace Ready

• Operating range:

  • -40°C to 120°C

• Standard headspace GC methods

• Moderate temperature conditions

10 mm Center Hole – Autosampler Access

• Open center design allows:

  • Easy needle penetration

  • Consistent injection performance

✅ Supports automated headspace systems

Crimp Top Design – Secure Seal Integrity

• 20 mm aluminum crimp cap

• Provides:

  • Reliable sealing

  • Reduced sample loss

  • Consistent vial closure

✅ Essential for accurate GC headspace analysis

Designed for 20 mm Headspace Vials

• Compatible with:

  • 20 mm crimp‑top headspace vials

✅ Ensures:

• Proper fit

• Reproducible analytical results

Cost‑Effective Solution – Budget Friendly
