MODELS: GC50 / GC51
GC Mass Flow Controller
Supercompact Gas Flow Control for Benchtop and Laboratory Systems
The GC Series delivers precise, stable gas flow control in an ultra-small footprint, 20 X 40 X 60 mm. Designed for non-GMP tabletop biotech, laboratory systems, and cost-sensitive OEM platforms, GC combines value-based MEMS technology with practical performance and in-situ calibration capability.
Features & Benefits
- In-Situ Verification & Recalibration with BCAT Software: Minimize spares inventory. Reduce downtime. Keep systems running on your schedule.
- Wide Control Range, 100:1 Turndown Ratio, Across Full Scale: Cover more operating conditions with a single device. Simplify design and reduce SKUs.
- Stable, Repeatable Performance, 1.5% S.P. ±0.5% F.S. accuracy
±0.25% repeatability: Dependable flow control for lab and pilot applications without premium platform cost. - Excellent Valve Shut-Off, Leak-by < 0.005 sccm: Improve process integrity and reduce unwanted gas flow when closed.
- Simple Integration, Analog I/O + Modbus RTU (RS-485): Integrates easily into new or existing control systems without added complexity.
- Safe Area Certified & Globally Compliant: Supports global deployment and regulatory alignment for laboratory and OEM systems.
Applications
- Benchtop bioreactors
- Lab-scale fermentation systems
- Media preparation systems
- Analytical equipment
- Medical and respiratory analyzers
- Cost-sensitive OEM platforms
