Field of application
The Raman Rxn-45 probe capitalizes on the power of Raman in bioprocess manufacturing by measuring multiple, specific components in real-time for continuous, around-the-clock process feedback. It also meets the daunting sampling requirements of compliance, sterilization, port compatibility, and convenience. The Raman Rxn-45 probe was designed for installation in development and cGMP stainless-steel reactors and is successfully used to provide an analytical “eye” into large-scale bioprocesses.
Cell culture: glucose, lactate, amino acids, cell density, titer, and more
Fermentation: glucose, glycerol, acetate, methanol, ethanol, biomass, and more
Benefits
