Used Brooks Instrument Mass Flow Controller

How Much Does Cost in 2026?

Used Brooks Instrument mass flow controllers (MFCs) in 2026 range from $1,200 to $3,500, depending on model, condition, and RF-hour count. Refurbished units typically command $500–$1,000 more than used equivalents, due to factory recalibration and warranty. Savings vs. new OEM list prices (which average $8,000–$12,000) are 50–70%. Units with >40,000 RF-hours are prioritized for semiconductor applications, while lower-hour units may suit industrial use. Prices reflect 2026 market trends, with stable demand from wafer fab and chemical processing sectors. Note: Part numbers like GF100-4 or SLA-1000 are critical for pricing accuracy. Sourcing lead times are 2–4 weeks post-verification, per 2026 inventory cycles.

Specifications and Compatible Tools

Key specs include 120V AC power, 60Hz frequency, and flow rates up to 100 sccm. The GF series operates at 20–30 psi differential pressure, while SLA models support 5–100 sccm ranges. Compatible tools include Applied Materials’ Centura PECVD (model 400, 2020–2023) and Tokyo Electron’s Vamos PECVD (model 450, 2021–2024). Avoid units with part numbers like GF100-4B, which are incompatible with newer semiconductor etch systems. Always verify RF-hour counts and calibration dates—2026 buyers should prioritize units with >20,000 hours and calibration certificates from 2024 or later.

What to Check Before Buying a Used in 2026

1. RF-hour verification: Confirm units with >40,000 RF-hours for 2026 semiconductor applications. Lower-hour units may lack precision for advanced processes.
2. Calibration test: Use a Brooks 4000 Series Meter to validate flow accuracy within ±1.5% of setpoint. Reject units with deviations exceeding 2.5%.
3. Pressure drop test: Measure differential pressure at 20 psi; deviations above 5% indicate internal wear.
4. Electrical integrity: Test insulation resistance with a megohmmeter; values below 10 MΩ are unsuitable for 2026 high-purity environments.
5. Lifecycle assessment: Prioritize units manufactured between 2015–2020; post-2020 models may lack 2026-compatible firmware.

FAQ

Q: Are used Brooks MFCs better than refurbished in 2026?
A: Used units offer 50–70% savings vs. new, but refurbished models include factory recalibration and 2026 warranty. Choose based on budget and process requirements.

Q: Can I use a Brooks GF100-4 in a 2026 etch tool?
A: No. GF100-4 is incompatible with 2026 etch systems requiring SLA-1000 models. Always verify part numbers against compatible tool specs.

Q: How do I test a used MFC’s flow accuracy in 2026?
A: Use a Brooks 4000 Series Meter to measure deviation from setpoint. Reject units with >2.5% error, as per 2026 semiconductor standards.

Q: What’s the difference between GF and SLA series in 2026?
A: GF models are for general industrial use, while SLA series meet 2026 semiconductor purity standards. SLA units are 20–30% more expensive but essential for advanced wafer processing.
