Autosampler Syringes

Chrom Tech supplies a complete selection of Agilent GC Autosampler Syringes, including Blue Line and Gold Standard 7693A models designed for high-precision injections across GC and GC/MS workflows. As an authorized Agilent distributor, Chrom Tech ensures customers receive verified, application-ready consumables that maintain system performance, injection reproducibility, and long-term instrument reliability.

Blue Line Autosampler Syringes with Fitted Plungers are individually matched to each glass barrel, providing a tight, consistent seal ideal for homogeneous liquid samples. Because each plunger is custom-fit, plungers are not interchangeable—preserving the precision required for reliable quantitative injections.

Blue Line PTFE-Tipped Plunger Syringes support both gas and liquid applications. The PTFE seal reduces carryover, improves resistance to chemical attack, and significantly increases syringe longevity. Chrom Tech carries replacement plungers for these models, offering a cost-efficient maintenance path for high-throughput labs.

Agilent’s advanced dual-gauge tapered needle combines the upper strength of a 23-gauge needle with the injection flexibility of a 26s-gauge tip. This design supports split/splitless, pulsed split, and on-column injection techniques, including compatibility with 0.53 mm ID columns. All plungers are manufactured with high-grade stainless steel to ensure chemical stability and smooth operation.

Whether you’re maintaining routine GC throughput or performing sensitive trace-level analysis, Chrom Tech provides the genuine Agilent syringes, replacement plungers, and sample delivery components required to keep your autosampler performing with accuracy and repeatability.
