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 preserve adsorption‑prone compounds during routine analysis. The 9509C‑3XWAP‑RS RSA™ Snap‑Top Vial & Cap Kit pairs this surface treatment with amber glass for light protection and the speed of snap‑top handling, supporting efficient workflows in busy laboratories.
This kit is well suited for routine and screening applications where rapid sample preparation, autosampler responsiveness, and analyte protection are prioritized.
Snap‑top vials do not seal as tightly as screw‑top systems, but they offer significantly faster handling and ease of use in applications where maximum seal integrity is not required.
Snap‑Top Cap & Pre‑Slit Septa System for High‑Throughput Workflows
The included blue snap caps are fitted with ultra‑pure silicone rubber / PTFE pre‑slit septa, allowing consistent needle penetration with reduced resistance compared to non‑slit septa. Caps seal with a simple downward press, eliminating the need for torquing or threading.
This snap‑on system supports:
Rapid vial preparation at the bench
Faster autosampler loading and unloading
Consistent cap placement across operators
Reliable, repeatable injections
Because snap‑top systems rely on mechanical engagement rather than threaded compression, they are best suited for short runs, screening methods, and routine analyses rather than long unattended sequences or volatile analytes.
When to Choose Snap Tops vs. Screw Tops
RSA™ snap‑top vials are intended for applications where speed, convenience, and light protection outweigh the need for maximum sealing performance.
Recommended for:
High‑throughput LC or HPLC screening
Routine analytical testing
Method development and scouting runs
Short autosampler dwell times
Light‑sensitive samples requiring amber glass
Not recommended for:
Critical quantitative LC‑MS/MS analyses
Volatile analytes or long unattended sequences
Applications requiring maximum seal integrity
For critical or long‑term autosampler applications, RSA™ screw‑top vials are recommended.
Easy Purchase Pack Convenience
RSA™ Easy Purchase Packs simplify ordering, inventory management, and daily lab operation by pairing reduced surface activity vials with their correctly matched snap caps. The reclosable packaging helps keep components organized, clean, and readily accessible, reducing handling errors and setup time during routine laboratory use.
This kit format is ideal for laboratories performing frequent, high‑volume analyses.
