Optimize Your Process

Engineered to fit within a variety of bioreactors, this instrument delivers precise, real-time data that increases your understanding of critical fermentation and cell culture processes. This data can help you gain insight into cell metabolism and other changes within your bioreactor.

The 8500 allows you to monitor dissolved CO₂ via real-time display of digital data or you can use the instrument''s plot function to see the data graphically. You may also upload data to your computer or incorporate the output signal into your control processes. Data points can be logged as frequently as every 15 seconds, but can be set at longer intervals to reflect the length of your run.
