Chrom Tech provides a full range of GC autosampler vials—including crimp top, headspace, and accessory options—for precise and reliable gas chromatography workflows. Our crimp-style GC vials are trusted for superior sealing performance, making them ideal for volatile compound analysis where evaporation control is essential.

Most gas chromatography vials use an 11 mm closure and are available in multiple cap colors and septa configurations to match your specific autosampler setup. One of our most popular options, the 11 mm wide-mouth crimp top vial, provides a 40% larger opening than standard vials—simplifying pipetting and enhancing autosampler precision without compromising compatibility.

Chrom Tech stocks both wide-mouth and standard opening GC vials with corresponding closures and inserts. All glass vials are manufactured from Type I borosilicate glass, offering outstanding chemical resistance and thermal stability for aggressive reagents and solvents.

Crimp top vials are the benchmark for low-evaporation and tamper-proof sealing, making them a preferred choice in regulatory or chain-of-custody environments. Standard autosamplers typically accommodate 2 mL (12 × 32 mm) vials—the most widely used format in GC laboratories.

For limited-volume or repeat-injection analyses, Chrom Tech offers pre-assembled vial and insert combinations that save handling time and ensure consistent injection performance. These configurations are ideal for trace-level work and high-throughput applications.

Key Definitions ▸
Crimp Top Vial
A glass vial sealed with an aluminum crimp cap to provide the most secure, airtight closure—ideal for volatile gas chromatography samples requiring maximum evaporation resistance.
Headspace Vial
A vial designed for headspace GC analysis, allowing gas-phase sampling above the liquid sample. Available in screw thread or crimp finishes.
Wide-Mouth Opening
An 11 mm vial opening that improves pipette access and autosampler needle targeting while maintaining compatibility with standard GC tray formats.
Type I Borosilicate Glass
High-purity, chemically inert glass commonly used for chromatography vials due to its thermal stability and resistance to aggressive solvents.
Vial Insert
A small glass or polymer insert placed inside a GC vial to reduce dead volume and improve injection consistency for limited-volume samples.
Frequently Asked Questions ▸
Why are crimp top vials preferred for GC?
Crimp top vials ensure a superior, airtight seal that prevents evaporation and maintains sample integrity, essential for volatile GC analytes.
Are wide-mouth vials compatible with standard autosamplers?
Yes. Chrom Tech’s 11 mm wide-mouth GC vials maintain full autosampler compatibility while providing easier pipetting and needle targeting.
Do you offer pre-loaded vial and insert combinations?
Yes. Chrom Tech offers pre-assembled vials with inserts for small-volume or repetitive injection workflows, reducing setup time and improving consistency.
