Certified Vials, Caps, Septa, & Inserts

Importance of Certified Vial Quality

High‐quality sample vials are critical to reliable chromatographic analyses. Variability in vial materials and manufacturing can introduce trace contaminants, ghost peaks, and inconsistent sample recovery. Certified vials with rigorous quality control reduce downtime, limit rework, and protect sensitive detectors in GC, LC, and MS workflows.

Overview of Phenomenex Verex Certified Vial Products

Phenomenex Verex™ line offers a comprehensive portfolio of autosampler vials, closures, septa, and inserts engineered for maximum purity and compatibility. Verex products are designed to meet three certification levels:

• Level 1: Certified – full lot traceability, dimensional verification, and defect‐free standards
• Level 2: Certified PLUS – additional cleanliness and performance testing
• Level 3: Certified MSQ – ultra‐clean, mass spec-grade for highest sensitivity applications

Quality Assurance and Testing Methodology

All Verex vials are manufactured under ISO 9001:2015, using USP-grade Type 1 borosilicate glass (33- or 51A-Expansion) or medical‐grade polypropylene. Each lot undergoes:

• Machine vision inspection for dimensional tolerances
• Cleanroom packaging to eliminate particulates
• Cleanliness testing to verify low organic bleed and ion content
• Certificate of Conformance for complete lot traceability

Product Range and Key Features

The Verex portfolio accommodates a wide range of sample volumes and applications:

• Crimp-top vials (2 mL) with PTFE, PTFE/Silicone, or PTFE/Rubber septa for long-term, leak-free storage
• Snap-top vials (2 mL) with easy on/off sealing for rapid throughput and non‐volatile samples
• Screw-thread vials in 8, 9, 10, and 13 mm formats, including bonded-in septa, press‐fit caps, and assembled kits
• Headspace vials (6–20 mL) in flat or round bottom, with specialized magnetic and pressure‐release caps
• VOA/ASE and storage vials (20–40 mL) in clear or amber glass with PTFE/urethane liners for volatile organic analysis and solvent extraction
• Specialty vials for micro‐sampling: Max-Recovery CD, Qsert fused-insert, v-Vial, µVial series offering residual volumes below 5 µL
• Plastic protein/peptide-compatible vials in polypropylene to eliminate adsorption and pH shifts

Benefits and Practical Applications

Verex certified vials deliver:

• Enhanced reproducibility by eliminating ghost peaks and sample loss
• High chemical compatibility with virtually any autosampler platform
• Guaranteed defect-free performance backed by a 45-day satisfaction guarantee
• Innovative, user-friendly packaging with dispenser boxes and convenience kit carriers
• Online cross-reference tool to match existing part numbers and simplify transitions

Applications span pharmaceutical QC, environmental monitoring, food testing, clinical research, and advanced MS workflows.

Future Trends and Potential Developments

Advances in vial technology will focus on:

• Further miniaturization for nanoliter and microfluidic sampling
• Enhanced inert coatings to suppress ultra-trace contamination
• Sustainable materials and recyclable packaging
• Smart vials with RFID or barcoding for automated inventory and chain-of-custody tracking

Conclusion

Phenomenex Verex certified vials represent a state‐of‐the‐art solution for demanding chromatographic and mass spectrometry applications. Their rigorous quality management, broad product range, and user-centric design help laboratories achieve reproducible results, protect instrument uptime, and streamline workflows.
