In situ bioreactors made easy
Compact in-situ sterilizable bioreactor

Is the first step always the hardest? Not with the Techfors-S. The Techfors-S contains exactly the same components as our bench bioreactors. This ranges from the pumps via the gassing line to the touch screen controller and the associated software. Both beginners as well as process experts will be able to manage easily.



  • Working volume from 3 to 30 l
  • Double jacket made of 316L stainless steel
  • Individually configurable with a selection of different impellers, spargers and special accessories
  • Up to 14 ports for sensors (anti-foam, optical density, pH, pO2, redox, conductivity, live cell density, etc.)
  • 1 port in the bottom of the vessel for harvesting/sampling
High-performance pumps
  • Basic setup includes four easy-load precision pumps per culture vessel (option of two more)
  • Gravimetric feeding (with external scale)
  • Profile-based pump-speed control with eve®
  • Customer-specific gassing with up to 5 gas lines
  • Feed via rotameter or mass-flow regulator
  • Cascades may be configured in serial or in parallel for controlling the pO2 via the stirrer speed, gassing rate, gas composition, etc.
  • Customers may choose from digital (Modbus) or analog sensors.
  • Product calibration of the pH sensor for reliable measurements during long-running bioprocesses
  • If required, additional sensors and actuators can be connected.
12″ Touchscreen Controller
  • Touchscreen with integrated OPC server
  • Reliable measurement and setting of the bioprocess parameters and communication with eve®
  • Up to 24 selectable parameters, such as temperature, stirring speed, pH, pO2, anti-foaming agent, feed
eve® Bioprocess Platform Software
  • Planning, controlling and analysing bioprocesses
  • Integrated workflows, devices and bioprocess knowledge
  • Integrates bioreactors and analytical instruments, regardless of the manufacturer
  • Web-based project organisation
  • Communication using the latest OPC UA (Minifors 2) or OPC XML-DA standard (Multifors 2, Labfors 5, Techfors-S, Techfors)
  • Synchronisation of process-related events such as sampling or inoculation
