Tandem MULTI: A Multi-Line Off-Gas Analyzer

The Tandem MULTI gas analyzer provides real-time, on-line, off-gas analysis of CO₂ and O₂ for microbial and cell culture experiments and is compatible with a wide range of bioreactor systems. The Tandem MULTI supports multiple gas line inputs for parallel bioreactor platforms, with a user-definable sampling interval. The real-time feedback enables automation of experimental operation, delivering greater control of the bioprocess and facilitating increased reliability and repeatability of experiments.
