CP-1805GSA-RS - 2ml amber Write On Vials, 100/pk

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 CP-1805GSA-RS RSA™ Snap‑Top Vial & Cap Kit combines this reduced surface activity with the speed and convenience of snap‑on caps, while amber glass provides added protection for light‑sensitive analytes.

This kit is well suited for laboratories performing frequent analyses where rapid sample preparation and efficient autosampler handling are priorities.

Snap‑top vials do not seal as tightly as screw‑top systems, but they offer significantly faster handling and improved autosampler responsiveness in applications where maximum seal integrity is not required.

Snap‑Top Cap & Septa System for High‑Throughput Workflows

The included light blue snap caps seal instantly with a simple downward press, eliminating the need for torquing or threading. This snap‑on design supports:

• Rapid vial preparation at the bench

• Faster autosampler loading and unloading

• Consistent cap placement without over‑ or under‑tightening

Because snap‑top systems rely on mechanical engagement rather than threaded compression, they are best suited for short runs, screening methods, and routine analyses 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 and convenience 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 requiring amber glass for light protection

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 lab operation by pairing reduced surface activity vials with their correctly matched caps. The reclosable kit packaging helps keep components organized, clean, and readily accessible during routine use, reducing handling errors and setup time in busy laboratory environments.

This format is ideal for laboratories performing frequent, high‑volume analyses.
