GF125C-107762 is a configured Brooks Instrument GF125C metal-sealed thermal mass flow controller record. Official Brooks GF100-series documentation supports the GF125 pressure-transient-insensitive metal-sealed MFC family and the C MultiFlo-capable configuration code; the configured suffix 107762, exact gas/range, protocol, fittings, valve state, and process options must be verified from the unit label or build record. Stored auction evidence repeatedly describes this suffix as SF6, 2000 SCCM, which is retained only as observed configuration context
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
Part identifier
GF125C-107762
Manufacturer
Brooks Instrument
Device type
GF125C configured metal-sealed thermal mass flow controller
Series family
GF100 / GF120 / GF125 metal-sealed high-purity thermal mass flow controller family
Configuration
Configured-unit rule
Gas, full-scale range, communication interface, valve state, fitting package, downstream condition, and process options vary by configured model code and must be read from the unit label or Brooks build record
GF125 package code context
Brooks GF100-series ordering documentation identifies code 125 as the pressure-transient-insensitive GF125 package with 3 sccm to 55 slpm N2-equivalent flow range, 300 to 700 ms response, 5 microinch Ra finish, and +/-1.0% of set point accuracy context
C configurability code context
Brooks GF100-series ordering documentation identifies code C as MultiFlo capable, allowing standard bins or selected gas/range configuration
Applications
Application domain
Semiconductor, MOCVD, thin-film, and other high-purity gas flow-control applications requiring an all-metal flow path
Performance
Flow accuracy
Series-level accuracy is configuration dependent; official Brooks GF100/GF120/GF125 analog and DeviceNet documentation lists +/-1% of set point above 35-100% and +/-0.35% full scale over 2-35% based on factory N2 calibration
Settling time
For GF125 normally closed valve configurations, official Brooks documentation lists 300 ms for 3-860 sccm, 400 ms for 861-7200 sccm, 500 ms for 7201-30000 sccm, and less than 700 ms for 30001-55000 sccm
Materials
Wetted path standard
Brooks GF100/GF120/GF125 documentation lists SEMI F20 HP compliant wetted materials for the family
Controls
Communication interfaces
Official family documentation covers Analog/RS-485, DeviceNet, and EtherCAT variants; the exact interface for GF125C-107762 must be verified from the unit label or connector
Flow
Gas/range programmability
MultiFlo gas and range programmability is supported on applicable C-code configurations
Observed configuration
Stored auction gas/range combination
Stored auction records repeatedly describe GF125C-107762 as SF6, 2000 SCCM; this is observed listing context only, not an official Brooks model-wide specification
