What you are buying
A refurbished Agilent 7693 Tray (G4514), an autosampler tray. It holds and positions vials for the autosampler tower; it runs unattended sequences.
Every unit moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.
What Agilent says about this platform
Agilent scales the 7693A around the same modular tray system: 16 vials as a start, up to 150 vials for long unattended runs. The tray holds and positions each vial for the injector tower on its turn in the sequence. Agilent offers whole-tray heating, or cooling to sub-ambient temperatures, to condition samples before injection. A priority sample position lets an operator insert an urgent sample without stopping the running sequence.
What each component does
Vapor sampling
Holds and positions vials for the autosampler tower, presenting each one in turn so the injector always draws from the correct position.
Automated sequencing
Runs overnight sequences without an operator, working through the loaded tray on its own schedule.

What “GenTech Certified” means
Refurbishment at GenTech is a defined process, not a wipe-down. Every system moves through the same five stages.
1. Disassembly and rebuild. Solution Scientists strip the instrument down, clean each module inside and out, and rebuild it from the frame up. They replace pump seals, pistons, and check valves to specification.
2. Configuration and new parts. Solution Scientists install the options and modules you selected and fit new wear parts throughout. They replace the detector lamp with a new one and reset the lamp hours.
3. Diagnostic and performance testing. Solution Scientists tune and calibrate the instrument, run system diagnostics, and confirm detector wavelength accuracy. They test full-system pressure and gradient performance against OEM and published benchmarks using known reference chemicals.
4. Data package you approve before shipment. The verification data goes to you for approval before the system leaves the bench. You see exactly how the instrument performs before it ships.
5. Delivery and installation. The instrument ships in protective packing with a one-year warranty option and professional installation available from a GenTech Solution Scientist.
