Reduced Surface Activity Fused‑Insert Vials for Improved Recovery

RSA™ reduced surface activity fused‑insert vials are designed to improve recovery and reproducibility for low‑volume and trace‑level samples by integrating the insert directly into the vial. The fused construction eliminates variability associated with separate inserts, including misalignment, sample trapping beneath the insert, or inconsistent needle access.

The defined 300 µL sample reservoir, combined with reduced surface activity glass chemistry, supports consistent sample positioning and efficient aspiration—especially important for limited‑volume or high‑value samples. Clear borosilicate glass allows visual verification of sample volume and condition while maintaining low extractables and chemical inertness during autosampler residence.

AQR™ Ultra‑Pure Pre‑Slit Septa for LC‑MS Performance

The included light blue screw caps are fitted with AQR™ ultra‑pure silicone rubber / PTFE pre‑slit septa, engineered to minimize extractables and septum bleed in demanding LC‑MS and LC‑MS/MS workflows. The pre‑slit design supports smooth, repeatable needle penetration while reducing septum wear and coring during extended analytical sequences.

Matched vial and cap components ensure consistent performance across high‑sensitivity and high‑throughput applications.

Easy Purchase Pack Convenience

Easy Purchase Packs are a convenient way to order and inventory autosampler vials with their matching caps. The reclosable kit packaging keeps vial and cap types matched, organized, and clean, saving setup time and reducing handling errors at the bench.
