Reduced Surface Activity Wide‑Tip Fused‑Insert Vials for Improved Recovery
RSA™ reduced surface activity wide‑tip fused‑insert vials are designed to improve recovery and reproducibility for low‑volume samples while accommodating analytical methods that benefit from a broader needle access area. The fused construction integrates the insert directly into the vial, eliminating variability associated with loose inserts such as misalignment, sample trapping, or inconsistent needle positioning.
The wide‑tip 300 µL reservoir supports efficient aspiration and reliable sample access, particularly for viscous matrices or workflows requiring consistent needle engagement. Combined with reduced surface activity glass chemistry, these vials help support accurate quantitation for limited or high‑value samples. Clear borosilicate glass allows visual confirmation of sample volume and condition while maintaining low extractables and chemical inertness during autosampler residence.
AQR™ Ultra‑Pure Septa for Low‑Background LC‑MS Applications
The included light blue screw caps are fitted with AQR™ ultra‑pure silicone rubber / PTFE septa, engineered to minimize extractables and septum bleed in LC‑MS and LC‑MS/MS workflows. This septa configuration supports clean needle penetration and reliable sealing while maintaining extremely low background contribution.
Matched vial and cap components help ensure consistent analytical performance across extended sequences.
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, reducing setup time and minimizing handling errors at the bench.
