CP-1805GS-RS - 2ml Clear 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-1805GS-RS RSA™ Snap Top Vial & Cap Kit combines this reduced surface activity with the speed and convenience of snap‑on caps, making it ideal for high‑throughput and non‑critical workflows.

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

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

The included light blue snap caps are designed to 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

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

Easy Purchase Packs simplify ordering, inventory management, and daily lab use by pairing RSA™ snap‑top vials with their correctly matched caps. The reclosable packaging keeps components organized, clean, and accessible during routine laboratory operation, helping reduce handling errors and setup time.

This kit format is well suited for laboratories performing frequent, high‑volume analyses.
