CP-1870GSA-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-1870GSA-RS RSA™ Snap‑Top Vial & Cap Kit combines this surface chemistry with amber glass and pre‑slit septa, making it well suited for laboratories handling light‑sensitive analytes in high‑volume workflows.

Snap‑top handling allows rapid sample preparation and efficient autosampler operation, supporting productivity in routine and screening applications.

Snap‑top vials do not seal as tightly as screw‑top systems, but they provide significantly faster handling where maximum seal integrity is not required.

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

The included light blue snap caps are fitted with ultra‑pure silicone rubber / PTFE pre‑slit septa, designed to reduce needle resistance, minimize coring, and improve injection consistency during repeated sampling. 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 without operator variability

• Reliable needle penetration using pre‑slit septa

As with all snap‑top systems, mechanical engagement favors speed and convenience over maximum sealing performance, making them best suited for short runs and routine analyses.

When to Choose Snap Tops vs. Screw Tops

RSA™ snap‑top vials are intended for applications where speed, light protection, 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

• Light‑sensitive samples requiring amber glass

• Repeated injections benefiting from pre‑slit septa

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
