Catalog Number - 9502C-0-20-S

The 9502C-0-20-S MICROSOLV Crimp Caps are engineered with a 1.0 mm thick, triple‑layer PTFE / silicone rubber / PTFE septa, providing enhanced durability, improved resealing, and effective needle wiping performance.

Designed for 11 mm crimp‑top and snap‑top, 12 × 32 mm autosampler vials, these caps are especially suited for legacy autosamplers and applications where needle cleanliness and septa longevity are critical.

Triple‑Layer Septa – Enhanced Performance

• Construction:

  • Red PTFE / White Silicone Rubber / Red PTFE

• Total thickness: 1.0 mm

• Provides:

  • Improved resealing vs. standard silicone/PTFE

  • Enhanced durability under repeated injections

✅ Ideal for extended autosampler sequences

Needle Wiping Functionality

• Designed to clean (wipe) the injection needle during penetration

• Helps reduce:

  • Carryover

  • Sample contamination

✅ Particularly useful for older autosampler systems

Optimized for Legacy Instruments

• Specifically designed for:

  • Agilent 1050 and similar systems

• Improves:

  • Needle cleanliness

  • Injection consistency

✅ Excellent choice for older HPLC platform compatibility

Crimp Top Design – Secure Sealing

• 11 mm aluminum crimp cap

• Provides:

  • Airtight seal

  • Reduced evaporation

  • Reliable storage and injection performance

✅ Suitable for volatile and non‑volatile samples

Broad Vial Compatibility

• Fits:

  • 11 mm crimp‑top vials

  • 11 mm snap‑top vials (with proper tools)

• Standard 12 × 32 mm autosampler format

✅ Compatible with most HPLC, LC‑MS, and GC‑MS systems

Durable Aluminum Construction

• Silver aluminum cap body

• Ensures:

  • Consistent crimping

  • Strong mechanical seal

  • Long‑term reliability

✅ Supports repeatable analytical workflows

Typical Applications

• Legacy HPLC systems (e.g., Agilent 1050)

• LC‑MS and HPLC autosampler workflows

• Applications requiring:

  • Needle wiping

  • Reduced carryover

• Routine analytical testing

Important Usage Notes

• Requires crimping tool for proper installation

• Thicker septa may require:

  • Slightly higher needle force

• Ideal when:

  • Improved resealing and durability are needed

  • Standard septa do not provide adequate cleaning or longevity
