Reduced Surface Activity with Ultra‑Low‑Volume Fused Insert Design
RSA™ (Reduced Surface Activity) autosampler vials are engineered to minimize analyte interaction with glass surfaces, preserving sample integrity for adsorption‑sensitive and trace‑level compounds. The 9532C‑1CP‑RS RSA™ Snap‑Top Vial & Cap Kit incorporates a precision‑formed 300 µL fused glass insert, permanently integrated into each vial to support ultra‑low‑volume injections with maximum reproducibility.
Unlike removable or drop‑in inserts, the fused insert is manufactured as part of the vial body, eliminating misalignment, dead volume, and contamination risks associated with separate components. All wetted surfaces benefit from RSA™ surface chemistry, making these vials among the highest‑purity, highest‑performance low‑volume autosampler vials available.
This configuration is specifically designed for laboratories working with limited sample volumes, high‑value compounds, or adsorption‑prone analytes, where vial performance directly influences analytical success.
Advantages of the 300 µL Fused‑Insert RSA™ Vial
The integrated fused insert geometry places low sample volumes precisely at the needle entry point while maintaining exceptional surface inertness throughout the vial. Key benefits include:
Maximum recovery from very small sample volumes
Exceptional injection‑to‑injection reproducibility
Elimination of loose, tilted, or extractable‑generating inserts
Reduced adsorption of sensitive compounds
Reliable, predictable autosampler performance
These characteristics make fused‑insert RSA™ vials an intentional investment for workflows where sample conservation and data integrity outweigh consumable cost.
Snap‑Top Caps with Ultra‑Pure AQR Septa
The included light‑blue snap‑top caps are fitted with clear AQR (Advanced Quality Rubber) silicone rubber / clear PTFE ultra‑pure septa, selected for applications requiring maximum cleanliness and minimal background interference.
These septa provide:
Extremely low extractables
Clean needle penetration with minimal coring
Reliable resealing for short autosampler dwell times
The snap‑on cap design enables fast, consistent sealing with a simple downward press, supporting:
Rapid sample preparation
Efficient autosampler loading
Uniform cap engagement without torque variability
As with all snap‑top systems, this closure method prioritizes speed and consistency rather than long‑term vapor containment.
When to Choose Fused‑Insert Snap‑Top RSA™ Vials
This kit is optimized for laboratories that require ultra‑low‑volume performance with premium surface chemistry.
Recommended for:
Trace‑level HPLC analysis
Adsorption‑sensitive or low‑abundance analytes
Very limited or precious samples
Method development and confirmation studies
Applications requiring ultra‑pure septa materials
Not recommended for:
Volatile analytes
Long unattended autosampler sequences
Applications requiring maximum sealing integrity
For extended runs or volatile compounds, RSA™ screw‑top fused‑insert vial systems are recommended.
RSA™ Easy Purchase Pack Convenience
RSA™ Easy Purchase Packs pair precision‑matched vials and caps to simplify procurement, inventory management, and daily laboratory operations. Reclosable packaging keeps high‑value components clean, organized, and protected during use, reducing handling errors and setup time.
This format is ideal for laboratories performing frequent high‑sensitivity analyses where material consistency and cleanliness are critical.
