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‑3WAP‑RS RSA™ Snap‑Top Vial & Cap Kit combines this surface chemistry with amber glass and pre‑slit septa, making it well suited for laboratories handling light‑sensitive analytes in high‑volume workflows.
Snap‑top handling allows rapid sample preparation and efficient autosampler operation, supporting productivity in routine and screening applications.
Snap‑top vials do not seal as tightly as screw‑top systems, but they provide significantly faster handling where maximum seal integrity is not required.
Snap‑Top Cap & Pre‑Slit Septa System for High‑Throughput Workflows
The included light blue snap caps are fitted with ultra‑pure silicone rubber / PTFE pre‑slit septa, designed to reduce needle resistance, minimize coring, and improve injection consistency during repeated sampling. Caps seal with a simple downward press, eliminating torquing or threading.
This system supports:
Rapid vial preparation at the bench
Faster autosampler loading and unloading
Consistent cap placement without operator variability
Reliable needle penetration using pre‑slit septa
As with all snap‑top systems, mechanical engagement favors speed and convenience over maximum sealing performance, making them best suited for short runs and routine analyses.
When to Choose Snap Tops vs. Screw Tops
RSA™ snap‑top vials are intended for applications where speed, light protection, and injection consistency outweigh the need for maximum sealing performance.
Recommended for:
High‑throughput LC or HPLC screening
Method development and scouting runs
Routine analytical testing
Short autosampler dwell times
Light‑sensitive samples requiring amber glass
Repeated injections benefiting from pre‑slit septa
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 control, and daily lab use by pairing reduced surface activity vials with their precisely matched caps. The reclosable packaging keeps components organized, clean, and accessible during routine operation, reducing handling errors and setup time in busy laboratories.
This kit format is well suited for labs performing frequent, high‑volume analyses.
