GF125C-205385 is a configured Brooks Instrument GF125CXXC metal-sealed thermal mass flow controller in the GF100/GF120/GF125 high-purity thermal mass flow controller platform. Stored auction evidence and exact listing records show several observed contexts for this configured part, including N2 7200 SCCM title wording, Ar 6000 SCCM title wording, and an exact GF125C-205385 / GF125CXXC-SH467.2L-CXVODX-1121AX-000 listing with Ar 4000 SCCM, DeviceNet, surface-mount fitting, and AMAT 0190-49896-05 context. These listing observations should not be treated as interchangeable calibration specifications; verify the physical unit label and calibration paperwork before reuse
