Brooks Instrument GF125C Metal-Sealed Mass Flow Controller
About this part
GF125C-100107 is a configured Brooks Instrument GF125C / GF100-family metal-sealed thermal mass flow controller identifier used in high-purity gas delivery contexts. Official Brooks documentation supports GF100/GF120/GF125 family-level specifications, while exact gas, range, protocol, fitting, valve, and surface-finish details must be confirmed from the unit label. Stored Sonisys auction evidence for this exact configured identifier observes H2 at 500 SCCM
Unit-specific configuration
Historical listing records identify this part as H2 at 500 SCCM. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.

Key Facts
Specifications
| Part identifier | GF125C-100107 |
| Device type | Configured Brooks metal-sealed thermal mass flow controller |
| Series family | Brooks GF100 / GF120 / GF125 metal-sealed mass flow controller and meter family |
| Configured-unit rule | Gas, full-scale range, communication interface, valve state, fitting package, pressure-transient option, and process options vary by configured model code and should be confirmed from the physical label or OEM build documentation |
| Application domain | High-purity and ultra-high-purity gas flow control for semiconductor, MOCVD, thin-film, and related process-gas delivery systems |
| Flow accuracy | Official GF100/GF120/GF125 family documentation lists accuracy as +/-1% of set point from 35-100% full scale and +/-0.35% full scale from 2-35% full scale, based on factory N2 calibration; applicability to this configured unit depends on the actual build and calibration |
| Settling time | Official family documentation lists normally closed GF125 response bins from 300 ms for low-flow ranges through less than 700 ms for higher listed ranges; exact response depends on the configured gas, range, and valve option |
| Wetted path standard | Official GF100/GF120/GF125 family documentation describes SEMI F20 HP-compliant wetted materials for the family |
| Communication interfaces | Official family documentation covers Analog/RS-485, DeviceNet, and EtherCAT variants depending on configuration |
| Gas/range programmability | Brooks MultiFlo gas and range programmability is supported on applicable GF-series configurations; do not infer a specific enabled gas table from the configured part number alone |
| Stored auction gas/range combinations | H2 500 SCCM (2 stored listing records) |
