Brooks Instrument GC Series Compact Gas Mass Flow Controllers
Product Overview
Brooks Instrument GC Series (GC50/GC51) offer supercompact gas flow control, specifically designed for benchtop laboratory systems and cost-sensitive OEM platforms. By leveraging advanced MEMS (Micro-Electro-Mechanical Systems) technology, the GC Series delivers high-performance thermal mass flow control in an incredibly small footprint. This ultra-compact design allows for seamless integration into space-limited environments such as bioreactors, analytical equipment, and medical analyzers without compromising on precision or stability.
Engineered for versatility, the GC Series features a wide 100:1 turndown ratio and a flow range up to 5000 sccm, allowing a single device to cover a broad array of operating conditions. Users benefit from simplified system designs and reduced spare parts inventory thanks to the in-situ verification and recalibration capabilities provided by Brooks’ BCAT software. With multiple connectivity options including Modbus RTU (RS-485) and various analog interfaces, the GC Series is a flexible, plug-and-play solution for modern laboratory and industrial gas delivery systems.
Features and Benefits
Take a look at some of the features and benefits of the GF40 Series
In-Situ Verification & Recalibration: Utilize Brooks Instrument BCAT software to verify accuracy and recalibrate units without removing them from the process line, drastically reducing maintenance downtime.
Inventory Consolidation: The multi-gas/multi-range capability allows a single device to be reconfigured for different setups, reducing the need to stock multiple spare part SKUs.
“Matchbox” Form Factor: The ultra-compact footprint allows for easy integration into dense OEM manifolds or crowded benchtop workstations where traditional MFCs won’t fit.
Simplified System Integration: Dual-mode communication (Analog and Digital) ensures the device “drops in” to legacy systems or modern PLC-controlled environments without needing expensive adapters.
Enhanced Process Integrity: Superior valve shut-off minimizes “leak-by” during idle periods, protecting sensitive samples in bioreactors or analytical equipment from unwanted gas exposure.
Global Regulatory Compliance: Fully certified for safe area use and global standards, making it the ideal choice for OEMs exporting equipment to international markets.
