Reduced Surface Activity with Fast, Convenient Snap‑Top Handling
RSA™ (Reduced Surface Activity) autosampler vials are designed to minimize analyte interaction with glass surfaces, helping preserve adsorption‑prone compounds during routine analysis. The 9509C‑3XWCP‑RS RSA™ Snap‑Top Vial & Cap Kit pairs this surface treatment with simple snap‑top handling and standard pre‑slit septa, supporting efficient autosampler operation in routine laboratory workflows.
This kit provides a practical balance of performance and cost for laboratories prioritizing speed and throughput over specialized needle‑protection features.
As with all snap‑top systems, sealing force is lower than screw‑top designs, but handling speed and operational efficiency are significantly improved for non‑critical applications.
Snap‑Top Cap & Standard Pre‑Slit Septa System for High‑Throughput Workflows
The included blue snap caps are fitted with ultra‑pure silicone rubber / PTFE standard pre‑slit septa, allowing direct needle penetration without the additional bonded Soft‑Guard™ layer used in other configurations. 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 across operators
Reliable injections with reduced septum coring versus non‑slit designs
When to Choose Snap Tops vs. Screw Tops
RSA™ snap‑top vials are intended for applications where speed and convenience 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
Applications where standard pre‑slit septa meet injection requirements
Not recommended for:
Critical quantitative LC‑MS/MS analyses
Volatile analytes or long unattended sequences
Applications requiring maximum seal integrity or advanced needle protection
For critical or extended autosampler applications, RSA™ screw‑top vials or Soft‑Guard™ septa kits are recommended.
Easy Purchase Pack Convenience
RSA™ Easy Purchase Packs simplify ordering, inventory management, and daily laboratory operation by pairing reduced surface activity vials with their correctly matched snap caps. The reclosable packaging keeps components organized, clean, and readily accessible, reducing handling errors and setup time in high‑throughput lab environments.
