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‑3EWCP‑RS RSA™ Snap‑Top Vial & Cap Kit combines this surface chemistry with fast snap‑top handling and Soft‑Guard™ septa technology, supporting efficient autosampler operation in busy laboratory environments.
This configuration is well suited for routine and screening workflows where productivity and injection consistency are priorities.
Snap‑top vials do not seal as tightly as screw‑top systems, but they offer significantly faster handling where maximum seal integrity is not required.
Snap‑Top Cap & Soft‑Guard™ Pre‑Slit Septa System for High‑Throughput Workflows
The included blue snap caps are fitted with white silicone rubber / red PTFE Soft‑Guard™ pre‑slit septa, bonded to provide controlled needle penetration and reduced needle stress. The Soft‑Guard™ design helps minimize coring and septum deformation during repeated injections.
The snap‑on design seals with a simple downward press, eliminating torquing or threading and supporting:
Rapid vial preparation at the bench
Faster autosampler loading and unloading
Consistent cap placement without over‑ or under‑tightening
Improved needle longevity and injection consistency
As with all snap‑top systems, mechanical engagement prioritizes speed and convenience over maximum sealing performance.
When to Choose Snap Tops vs. Screw Tops
RSA™ snap‑top vials are intended for applications where speed, gentle needle entry, 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
Applications benefiting from Soft‑Guard™ 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 management, and daily laboratory use by pairing reduced surface activity vials with their precisely matched caps. The reclosable packaging keeps components organized, clean, and accessible during routine operation, helping reduce handling errors and setup time.
This format supports efficient workflows in laboratories performing frequent, high‑volume analyses.
