CP-1870-03-RS - Vials,clear, snap top cap w/slit,300uL, 100pk

Advantages of the 300 µL Fused‑Insert RSA™ Vial

The integrated fused insert geometry precisely positions small sample volumes at the needle entry point while maintaining exceptional surface inertness. Key benefits include:

• Maximum recovery from very low sample volumes

• Highly consistent injection depth and reproducibility

• Elimination of loose or tilted inserts

• Reduced adsorption of sensitive or low‑abundance analytes

• Predictable, stable autosampler performance

These characteristics make fused‑insert RSA™ vials a deliberate choice for workflows where sample conservation and data quality take precedence over consumable cost.

Snap‑Top Caps with Ultra‑Pure Pre‑Slit AQR Septa

The included light‑blue snap‑top caps are fitted with clear AQR (Advanced Quality Rubber) silicone rubber / clear PTFE ultra‑pure pre‑slit septa. This septum configuration combines extremely low extractables with controlled, low‑force needle entry.

The pre‑slit design offers:

• Clean, repeatable needle penetration

• Reduced septum coring and needle stress

• Improved injection consistency for delicate needles

• Ultra‑low background interference

The snap‑on cap design seals with a simple downward press, supporting rapid vial preparation, efficient autosampler loading, and consistent cap placement without torque variability. As with all snap‑top systems, sealing performance favors speed and convenience over long‑term vapor containment.

When to Choose Fused‑Insert Snap‑Top RSA™ Vials with Pre‑Slit Septa

This kit is optimized for laboratories requiring ultra‑low‑volume performance with gentle needle entry and premium surface chemistry.

Recommended for:

• Trace‑level HPLC analysis

• Adsorption‑sensitive or low‑abundance analytes

• Very limited or precious samples

• Method development and confirmation work

• Applications benefiting from pre‑slit, ultra‑pure septa

Not recommended for:

• Volatile analytes

• Long unattended autosampler sequences

• Applications requiring maximum seal integrity

For volatile compounds or extended dwell times, RSA™ screw‑top fused‑insert systems are recommended.
