Tornado’s Hudson™ Bioreactor Raman Immersion Probe

Tornado’s Hudson Bioreactor Raman Immersion Probe enhances the power of Raman in bioprocess manufacturing by measuring multiple component concentrations and critical quality attributes (CQAs) in real-time for continuous, around-the-clock process feedback. There are many applications for process Raman applications in the “upstream” domain which require precise quantitative information, and this probe provides excellent data in both the fingerprint and CH-stretch regions, facilitating these demanding requirements. Advanced Raman probes like this one provide a perfect illustration of how fiber optics can be joined with other optical components to obtain a simple and flexible measurement.

Real-time process analysis for your bioprocessing needs

Its optical design is optimized for compatibility with Tornado’s Process Guardian and HyperFlux™ PRO Plus Raman analyzers and can be used for the superior representative sampling and measurement reproducibility for both turbid and transparent bioreactor contents, culture media, mammalian and bacterial cell types, and heterogeneous mixtures.
