Additional Info:
Reduced Surface Activity with Fast, Snap‑Top Convenience for Routine Workflows
RSA™ (Reduced Surface Activity) autosampler vials are engineered to minimize analyte interaction with glass surfaces, helping reduce adsorption losses during routine analytical use. The 9509C‑1EWCP‑RS RSA™ Snap Top Vial & Cap Kit combines RSA™ glass performance with the speed and convenience of snap‑on caps, making it well suited for high‑throughput, non‑critical autosampler workflows.
Snap‑top vial systems offer faster handling than screw‑top formats but do not seal as tightly, and are therefore recommended for applications where operational efficiency is prioritized over maximum sealing performance.
Snap‑Top Soft‑Guard™ Cap & Septa System
This kit is supplied with snap‑top caps fitted with white silicone rubber / red PTFE Soft‑Guard™ septa, bonded into blue polypropylene caps. The Soft‑Guard™ septa design provides:
Gentle needle penetration with reduced septum coring
Reliable performance during short injection sequences
Consistent septum positioning without torque variability
Because snap‑top seals rely on mechanical engagement rather than threaded compression, these caps are best used 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 less‑critical applications where speed and ease of use are the primary concerns.
Recommended for:
High‑throughput HPLC screening
Method development and scouting runs
Routine analytical testing
Short autosampler dwell times
Not recommended for:
Critical quantitative LC‑MS/MS analyses
Long unattended sequences
Volatile or highly evaporation‑sensitive analytes
For applications requiring maximum sealing integrity, RSA™ screw‑top vials are recommended.
Easy Purchase Pack Convenience
Easy Purchase Packs simplify ordering and daily lab operations by pairing RSA™ snap‑top vials with their correctly matched caps in a single, reclosable package. This packaging format helps keep components clean, organized, and properly matched during use, while reducing setup time and handling errors.
