Additional Info:
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‑3WCP‑RS RSA™ Snap‑Top Vial & Cap Kit pairs this surface treatment with rapid snap‑top handling and pre‑slit septa, making it a preferred choice for busy laboratories running frequent injections.
This configuration supports efficient sample preparation while maintaining analytical consistency in routine and high‑throughput methods.
Snap‑top vials do not seal as tightly as screw‑top systems, but they provide significantly faster handling and improved autosampler responsiveness where maximum seal integrity is not required.
Snap‑Top Cap & Pre‑Slit Septa System for High‑Throughput Workflows
The included light blue snap caps feature ultra‑pure silicone rubber / PTFE pre‑slit septa, designed to reduce injector force and needle coring while supporting rapid, repeatable injections. The snap‑on design requires only 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 over‑ or under‑tightening
Improved needle penetration consistency with pre‑slit septa
Because snap‑top systems rely on mechanical engagement rather than threaded compression, they are best suited for routine, high‑throughput applications rather than long sequences or volatile analytes.
When to Choose Snap Tops vs. Screw Tops
RSA™ snap‑top vials are intended for applications where speed, convenience, 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 pre‑slit septa for repeated injections
Not recommended for:
Critical quantitative LC‑MS/MS analyses
Volatile analytes or long unattended sequences
Applications requiring maximum seal integrity
For critical or extended autosampler applications, RSA™ screw‑top vials are recommended.
Easy Purchase Pack Convenience
RSA™ Easy Purchase Packs streamline ordering and inventory management by pairing reduced surface activity vials with their precisely matched caps. The reclosable packaging keeps components organized, clean, and accessible during daily laboratory use, helping reduce setup time and handling errors.
This kit is MICROSOLV’s most popular RSA™ Easy Purchase Pack, reflecting its broad suitability for routine laboratory workflows.
