Chromatography Vials, Inserts, and Closures
Chrom Tech offers a complete range of chromatography vials, inserts, and closures engineered for compatibility with all major autosamplers in GC, HPLC, and LCMS systems. Available in glass or plastic, these vials ensure leak-free performance, accurate sample recovery, and secure sealing for reliable results.
Choosing the right vial depends on sample volatility, sensitivity, and system compatibility. The industry standard 12 × 32 mm vial fits most autosamplers, while 20 mm headspace vials are used for specialized gas analysis. Screw thread, crimp, and snap top formats allow flexible closure options for every workflow.
Screw thread vials are preferred for HPLC/LCMS due to easy handling and tool-free caps. Crimp vials are ideal for GC applications, minimizing evaporation and ensuring tamper resistance. Snap top vials offer fast, convenient sealing for high-throughput environments.
Vials are available in Type I borosilicate glass for inertness, or in polypropylene and TPX polymer for cost-effective and chemical-resistant use. Use amber or black vials for light-sensitive samples, and pair them with PTFE/F217 closures for secure, resealable storage.
For limited sample volumes, Chrom Tech supplies pre-loaded vial inserts and low-volume configurations to minimize waste and maximize precision. All vials and closures are stocked and ready to ship for immediate lab use. Contact Chrom Tech for expert help selecting the right vial system for your application.
Frequently Asked Questions
Which vial type should I use for GC vs. HPLC applications?
Crimp vials are recommended for GC due to superior sealing and evaporation control, while screw or snap top vials are preferred for HPLC and LCMS systems.
What vial material is best for light-sensitive samples?
Amber glass or black polypropylene vials block UV and visible light, protecting light-sensitive analytes from degradation during handling and storage.
Do Chrom Tech vials fit all autosamplers?
Yes. Chrom Tech vials conform to standard autosampler dimensions and are compatible with Agilent, Thermo Fisher, Shimadzu, Waters, and other major LC/GC instruments.
