Agilent 1260 Infinity II HPLC G7129A High-Capacity Vialsampler Autosampler for Liquid Chromatography
Product Description
The Agilent 1260 Infinity II HPLC G7129A Vialsampler is a high-precision autosampler engineered for routine liquid chromatography applications in pharmaceutical quality control, environmental monitoring, and food analysis. This vial autosampler supports an injection volume range of 0.1 to 100 µL with 0.1 µL increments, operating reliably at pressures up to 60 MPa (600 bar / 8702 psi).
Key features include:
- Precision injection performance with less than 0.25% RSD for peak areas between 5 and 100 µL injections, ensuring reproducibility essential for molecular diagnostics and bioprocessing assays.
- Dual vial drawer design accommodates up to 132 vials, enhancing throughput for large sample sets common in biomanufacturing and synthetic biology workflows.
- Robotic gripper arm with stepper motor drive enables accurate, flexible vial handling critical for automated liquid chromatography and sample preparation.
- Automated needle washing system minimizes sample carryover, a key factor in maintaining integrity in gene editing and molecular cloning analyses.
- Overlapped injection functionality improves sample throughput, supporting efficient workflows in clinical diagnostics and biotechnology research.
- Low internal volume minimizes system dispersion, preserving chromatographic resolution and peak integrity across diverse biotechnology and pharmaceutical pipelines.
- Compatibility with Agilent InfinityLab LC systems and standard control software offers seamless integration in advanced LC-MS and analytical configurations.
- Optional thermostatted modules ensure stable temperature control for samples sensitive to thermal variation, critical for live-cell metabolite analysis and bioactive compound quantification.
This autosampler is widely adopted in biotechnology laboratories, including applications in molecular biology, bioprocess development, and synthetic biology, due to its robustness, automation, and precision in high-throughput liquid chromatography. Its technical specifications make it essential for biopharmaceutical production pipelines requiring accurate, reproducible injections and automated sample handling.
