YSI 2940/2980 OLM

4 and 8 Channel Online Monitoring Systems

For multiple and parallel bioreactor systems, our 4-channel and 8-channel sampling systems provide many simple and reliable online monitoring and control solutions for your bioreactor processes. Closed-loop monitoring and control capabilities are easily achieved for any scale of operation or type of bioreactor, including single-use systems.

Rapid, Accurate, and Interference Free  

The key to generating analyte-specific results in 60 seconds or less is YSI’s innovative biosensor technology. Using the inherent specificity of enzymes for a single target analyte, YSI’s immobilized enzyme electrodes allow for a rapid, accurate measurement to be made quickly.


Save Time and Money

YSI’s proprietary immobilized enzyme electrodes allow for rapid, accurate, and largely interference-free measurement to be made in about a minute. Sample analysis requires little or no preparation due to the YSI Biochemistry Analyzers' unique sample chamber design and membrane characteristics, which makes the enzyme electrode impervious to sample color, pH, turbidity, and other low molecular weight interferences.

Fully modular and with a range of upgrades available, the YSI 2900 and 2950 Series feature an intuitive graphical user interface and a touch screen display, making 2900 series analyzers the easiest to use and most cost effective way to measure the following chemistries in a wide range of matrices:

  • Glucose

  • Lactate

  • Glutamine

  • Glutamate

  • Ammonium

  • Potassium

  • Ethanol

  • Methanol

  • Sucrose

  • Galactose

  • Lactose

  • Choline

  • Glycerol

  • Hydrogen peroxide


If you're interested in online monitoring with 2 chemistries you may be interested in the YSI 2900M. We also offer the 2950D without online monitoring but it has the capability of offering up to 6 parameters!

Be sure to check out our add-on module that provides OPC data management for off-line YSI 2900 Series Biochemistry Analyzers or YSI 2900M Online Monitoring & Control Systems, too!
