CP-1870GS-RS - 2ml Clear Vial, Snap w/PTFE/SIl Slit,100/pk

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 CP-1870GS-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.
