Additional Info:
Reduced Surface Activity with Fast, Convenient Snap‑Top Handling
RSA™ (Reduced Surface Activity) autosampler vials are engineered to minimize analyte interaction with glass surfaces, helping reduce adsorption losses during routine analysis. The 9509C‑1XWCP‑RS RSA™ Snap Top Vial & Cap Kit combines this reduced surface activity with the speed and convenience of snap‑on caps, making it well suited for high‑throughput, non‑critical workflows.
Snap‑top systems provide significantly faster vial preparation and handling than screw‑top formats, but they do not seal as tightly. As a result, they are recommended for applications where speed and convenience are prioritized over maximum seal integrity.
Snap‑Top Cap & Septa System for High‑Throughput Workflows
The included blue snap caps are designed to seal with a simple downward press, eliminating the need for threading or torque control. This snap‑on design supports:
Rapid vial preparation at the bench
Faster autosampler loading and unloading
Consistent septum placement without risk of over‑ or under‑tightening
Because snap‑top seals rely on mechanical engagement rather than threaded compression, they are best suited for short runs, screening methods, and routine analyses, rather than long sequences or volatile analytes.
When to Choose Snap Tops vs. Screw Tops
RSA™ snap‑top vials are intended for less‑critical applications where ease of use and throughput are the primary requirements.
Recommended for:
High‑throughput HPLC screening
Method development and scouting runs
Routine analytical testing
Short autosampler dwell times
Not recommended for:
Critical quantitative LC‑MS/MS analyses
Long unattended sequences
Volatile or highly evaporation‑sensitive analytes
For critical applications requiring maximum sealing performance, RSA™ screw‑top vials are recommended.
Easy Purchase Pack Convenience
Easy Purchase Packs simplify ordering and daily laboratory workflows by pairing RSA™ snap‑top vials with their correctly matched caps in a single, reclosable package. This helps keep components clean, organized, and properly matched during use, reducing handling errors and saving setup time.
This kit format is ideal for laboratories performing frequent, high‑volume routine analyses.
