Catalog Number - 9502C-E-43T-S

The 9502C-E-43T-S Soft‑Guard™ Crimp Caps are designed for high‑throughput chromatographic applications, featuring pre‑slit white silicone / red PTFE septa that provide exceptionally easy needle penetration and consistent resealing.

Built with silver aluminum crimp caps, these closures ensure a secure, leak‑resistant seal, making them ideal for HPLC, LC‑MS, and autosampler-based workflows where injection reliability and instrument uptime are critical.

Compatible with 11 mm crimp‑top and snap‑top, 12 × 32 mm autosampler vials, these caps provide a balanced combination of ease of use and performance.

Soft‑Guard™ Pre‑Slit Septa – Easy Penetration & Consistent Performance

• White silicone / red PTFE septa

• Pre‑slit design reduces injection force

• Minimizes:

  • Needle resistance

  • Septa coring

  • Particle generation

✅ Ensures smooth, repeatable autosampler injections

Enhanced Resealing – Improved Autosampler Reliability

• Designed for:

  • Better resealing than standard septa

  • Reduced sample evaporation

• Supports:

  • Longer run sequences

  • Fewer missed injections

✅ Increases instrument uptime and analytical consistency

Crimp Top Design – Secure Seal Integrity

• 11 mm aluminum crimp cap

• Provides:

  • Airtight sealing

  • Reliable containment of volatile samples

  • Consistent performance under demanding conditions

✅ Ideal for critical analytical workflows

Compatible with Crimp & Snap Top Vials

• Fits:

  • 11 mm crimp‑top vials

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

• Standard 12 × 32 mm autosampler vial format

✅ Supports flexible lab configurations

Durable Aluminum Construction

• Silver aluminum cap body

• Ensures:

  • Uniform crimping

  • Strong mechanical seal

  • Long‑term performance

✅ Provides reliable and repeatable sealing

Optimized for High‑Throughput Workflows

• Ideal for:

  • HPLC autosamplers

  • LC‑MS and LC‑MS/MS systems

• Reduces:

  • Downtime

  • Injection variability

✅ Excellent for routine and high‑volume analysis

Typical Applications

• HPLC autosampler workflows

• LC‑MS and LC‑MS/MS analysis

• High‑throughput analytical labs

• Pharmaceutical and QA/QC testing

• Environmental and food analysis

Important Usage Notes

• Requires crimping tool for proper sealing

• Pre‑slit septa:

  • Reduce injection force

  • Slightly lower reseal strength vs. non‑slit

• Ideal when:

  • Autosampler performance and ease of penetration are priorities
