Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
Autosampler vials are small but exacting. A GC or HPLC autosampler picks up each vial and pierces its septum with a needle, so the vial’s dimensions, above all in the standard 12 × 32 mm 2 ml format, must be held to tight tolerances for the instrument to grip, seal and sample reliably over a long unattended run.
We make them from Type I borosilicate tubing glass, which keeps extractables low for trace-level work.
The vials are used for GC, GC-MS, HPLC and LC-MS analysis in autosampler workflows, for trace and residue testing, and for short-term sample archiving. Typical buyers are pharmaceutical and environmental QC labs, food and beverage testing labs, contract research organizations, and forensic and clinical labs. Low-volume inserts let small samples run in the standard vial format, and amber vials protect light-sensitive analytes.
The standard vial is a 12 × 32 mm Type I borosilicate body with a 9 mm screw, 11 mm snap or 11 mm crimp finish, sealed by a cap carrying a PTFE/silicone septum for the needle to pierce. PTFE faces the sample for chemical resistance, and silicone gives the septum its reseal. Clear and amber glass are available, with write-on patches and graduations as options. Compliance documentation for the glass type is available on request.
Match the cap and septum to your method and instrument, and avoid over-tightening screw caps, which can distort the septum and cause leaks or coring. Fill to the working volume rather than the brim so the needle depth stays within range. Use amber vials for light-sensitive analytes and inserts for small samples. Keep vials capped and boxed until use, since any contamination shows up in the chromatogram.
We convert Type I borosilicate tubing on precision forming machines that hold the body and finish to tight tolerances, then anneal and clean the vials for low-extractable use. Dimensional accuracy and glass cleanliness are checked in production. We can supply vials alone or as kits with fitted caps and septa, in custom pack counts, with printed write-on areas or graduations. Tell us your instrument model and we’ll match the finish and samples.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
