What’s causing variability in your bioreactor? It may not be biology—it’s often gas flow. Precise control of O₂, CO₂, and N₂ is critical to stabilizing DO, pH, and ultimately yield.

Sierra’s RedySmart® MEMS-based mass flow controllers help eliminate that variability with:
• No-drift, ultra-stable sensors
• High repeatability across runs
• Immunity to pressure & temperature fluctuations
• Compact, OEM-ready integration

Better flow control equals more consistent bioprocess results. Learn more How Digital Mass Flow Controllers Optimize Bioreactor Performance https://bit.ly/4ggpyXj
