G3286-80224, Rinse station, Agilent ASX-500 series autosampler

The Agilent ASX-500 rinse station is a replacement autosampler accessory that supports probe rinsing between scheduled sample measurements. The station provides the location where the autosampler probe can be washed to remove residual sample solution and reduce carryover before moving to the next vial. Its operation depends on the correct rinse-liquid supply, waste drainage, pump tubing, and autosampler control sequence. This rinse station is specified for the ASX-500 series autosampler and is not a complete liquid handling system. During maintenance, inspect the rinse pathway for deposits, damaged surfaces, or leaks and replace the station when cleaning or service cannot restore normal function. Install the replacement using the autosampler service procedure, reconnect the wash and drain lines, and run a rinse cycle to verify correct probe positioning and drainage. The original rinse-station component is marked obsolete in Agilent's current catalog; procurement should therefore be checked for available replacements or compatible service options before scheduling maintenance.
