Agilent Technologies G7157A 1260 Infinity II Preparative Autosampler, serial number DEAEL00632, manufactured 2021-04-28 per the rear instrument label. This is a flow-through vialsampler module designed for automated sample handling in preparative and purification HPLC workflows, and is intended to operate as part of an Agilent 1260 Infinity II / InfinityLab purification stack alongside a separate pump and detector. Per Agilent's published data for this model, the prep autosampler handles injection volumes from 0.1 uL up to 5 mL, supports preparative flow rates to 200 mL/min at pressures to 400 bar, and accommodates 2 mL and 6 mL vials with a maximum capacity of up to 132 vials for unattended sample purification. The unit is CAN/LAN/USB controlled; the rear panel shows LAN, USB, CONFIG, two CAN ports and the remote connector. The photos show the module with its sample compartment open, fitted with two vial trays, and an Agilent 900 uL analytical metering head with G7157-60000 high-flow assembly installed. The instrument label reads 100-240 V, 50/60 Hz, 350 VA and carries CE, CSA and other agency marks. The unit is a benchtop module sitting on a laboratory cart with an IEC power inlet and solvent/waste lines attached. The module was in service in an R&D laboratory and is identified in-house as 'HPLC 25'. No detector, pump or system controller is included in this listing; condition, operating hours and service history were not documented at the time of the site visit.
