Agilent 1290 Infinity G4226A Autosampler

This used Agilent 1290 Infinity G4226A Autosampler is a high performance sample injection module built for the demands of UHPLC analysis. Designed to deliver precise, low volume injections at high pressure, it supports the sharp peak shapes and fast run times that define modern ultra high performance chromatography, handling both single vial and batch sequence work with minimal carryover. The unit has been tested for injection accuracy and mechanical reliability prior to listing. Built to integrate with the 1290 Infinity UHPLC modular stack, this autosampler communicates over Agilent's standard system bus and works alongside compatible pumps, detectors, and thermostatted compartments already common in high end analytical labs. Its rapid injection cycle and minimized dispersion design make it well suited to pharmaceutical stability studies, metabolomics research, and other applications where analysis speed and reproducibility are critical. Precise temperature controlled sample storage options and thorough needle wash routines help protect sample integrity across long automated runs. For laboratories seeking to restore or expand UHPLC sample handling capability, this pre-owned autosampler offers dependable performance at a fraction of new equipment cost. It is a sound choice for research institutions, pharmaceutical QC groups, and contract testing labs that need proven high pressure injection performance without the lead time or expense of purchasing new hardware.
