Collection: Dissolved Oxygen Analyzers
Dissolved Oxygen Analyzers for Sale - New and Refurbished | mLab Supply
Dissolved oxygen (DO) analyzers measure oxygen concentration in liquid media for fermentation monitoring, water quality testing, and bioprocess control. mLab Supply sources new, refurbished, and surplus benchtop DO meters, portable analyzers, and inline DO sensors from leading manufacturers.
Related Measurement and Bioprocess Equipment
- Bioreactors and Fermenters - Inline DO monitoring and control for bioprocess applications
- pH Meters and Controllers - Inline pH monitoring paired with DO control in bioreactors
- Orbital Shakers - Shake flask culture where DO monitoring may be required
Common Use Cases
- Bioreactor and fermenter DO monitoring and cascade control
- Aquaculture and aquatic research oxygen monitoring
- Environmental water quality monitoring
- Wastewater treatment process control
- Cell culture media oxygenation monitoring
What to Look For
- Sensor type: Polarographic sensors require polarization time; optical (luminescent) sensors respond faster and require less maintenance
- Measurement range: Confirm the range covers your application - fermentation may require 0-200% air saturation
- Sterilizability: For inline bioreactor use, confirm the probe is autoclavable or SIP-compatible
- Response time: Faster response times are important for dynamic bioprocess control applications
