Description
The Thermo Scientific Dionex AS-AP Autosampler, model 074925, manufactured in 2023, is designed for precision and reliability in ion chromatography applications. Despite being a preowned unit, it performs initial self-checks successfully and exhibits smooth carousel and arm motions, indicating potential operational functionality. Featuring a high sample capacity of up to 81 10 mL vials and a unique moving-needle design, it ensures contamination-free and reproducible sample processing. The all-PEEK flow paths enhance compatibility with various eluents, minimizing metal contamination. Equipped with automated sample preparation functions, the Dionex AS-AP minimizes labor while maximizing efficiency. Temperature control options further enhance its adaptability for thermally sensitive samples. While operational software is not bundled, calibration and performance verification are advised post-installation.
Technician comment
Unit powers on, initializes, and passes self-check with no error indicators observed during basic functional testing. Carousel rotation, initialization & arm motion operate smoothly through multiple test cycles. Unit is preowned and sourced from a lab environment. Calibration and full performance verification are recommended after installation. Software not included.
