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 PRO is a self-contained O2 & CO2 gas analyzer. The PRO system comes with an internal gas pump and programmable display. It includes calibration functions, error reporting and dual 4-20mA outputs. An RS232 output is included for integration into control systems.

 

The Tandem PRO 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

  • On-line information, allows real-time calculation of RQ, CER, OUR, growth rate, KLa etc.

  • 0-10V and 4-20mA, with RS232 on PRO & Multiplex

  • Integrates to any reactor size (250ml – 100m3)

Dedicated, continuous, standard signals for all your reactors
