Online measurement of OTR, CTR and RQ for shake flask cultivations

The Kuhner TOM (Transfer-Rate Online Measurement) provides online measurements of the oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR), and respiratory quotient (RQ) for up to 16 individual shake flasks in a Kuhner incubator. The TOM provides the user with a better understanding of any bioprocess and allows for more efficient and effective optimization during process development. It is easily installed in any Kuhner shaker and is compatible with a variety of different shake flask types and sizes, including single use shake flasks.

Facts about Kuhner TOM

  • Measures online OTR, CTR and RQ for up to 16 shake flasks
  • Modular design: choose between 4, 8, 12 or 16 shake flasks
  • Zero footprint on the shaker tray, TOM is mounted above the shake flasks
  • Robust: durable sensors and static electronics
  • Available for Kuhner ISF1-X and ISF1-ZP, LT-X and Kuhner Kelvin+ incubators
  • Various glass and single use flasks can be connected
  • Option: Individual aeration for each shake flask with humidity and CO2 controlled air from the incubator

Modularity

The modularity of the Kuhner TOM allows the user to choose online measurements from 4, 8, 12, or 16 shake flasks. The TOM itself is mounted above the shake flasks and requires no space on the shaking platform, maximizing the capacity for shake flasks in the incubator.

KuhnerTOM

The Kuhner TOM captures the progress of multiple cultivations over time, providing an opportunity for the user to selectively schedule off-line sampling and analysis at critical time points. The TOM offers valuable insight on the viability and growth rate of shaken cultivations and will also help identify sub-optimal conditions, including oxygen limitation, substrate limitation, or product inhibition. The TOM also provides an opportunity for the systematic and rapid optimization of culture media and conditions (e.g. balancing different carbon sources or media additives, substrate uptake and product formation via RQ). The OTR, CTR, and RQ data captured from the TOM will accelerate any process development and facilitates scale-up.
