PRODUCT INFORMATION

  • Greater understanding of your cells and processes

  • Physiological state measurement on-line

  • Scale-up and scale-down predictions

  • Batch variation studies: feature analysis

  • Metabolic flux analysis and mass-balance calculations

The Tandem Mulitplex system is an economical choice for laboratory, pilot or production areas that have in excess of six fermentors or more. The multiplexed models have a local display, calibration functions, error reporting and selectable line control with an RS232 output for integration to control systems.

 

The Tandem MULTIPLEX is incredible value and offers you all these benefits:

Untitled-1
  • Accurate fed-batch control

  • Repeatable event decisions: induction, infection, harvesting etc.

  • Batch variation studies: anomaly analysis

Increase the reliability and repeatability of your processes

  • Metabolic activity based feeding

  • Repeatable event decisions: induction, infection, harvesting etc.

Automate your processes
