FNet - Fermentor Control Software - Description of fermentation software


FNet is a software for monitoring fermentation and cell culture processes with the LAMBDA MINIFOR laboratory fermenter. The software runs under Windows NT, 2000, XP, Vista, 7 and 8:

Ready to use software


  • • Easy to install


  • • The software recognizes the connected fermenters at start-up. Up to 6 fermenters, 12 integrators and 6 peristaltic pumps can be connected to one PC (figure 1)


  • • No need of programming knowledge


  • • All cables are easy to connect and have standard connectors


  • • No special add-in or license to buy for the connection of new fermentors





Display and graphs
(Figure 2) Fermentation Control Software FNet - main window

All the information (actual values, set points, graphs, alarms) of the fermenter is presented in the main window (figure 2):



  • • Actual values like temperature, pH, pO2, air flow rate, amount of base and acid, and an additional parameter X which could be for example the culture weight for continuous processes, optical density or an online biomass concentration measurement.


  • • Set point values like temperature, pH, pO2, air flow rate, agitation, another parameter X and one feed with a peristaltic pump


  • • Scalable graphs: The user can choose the fermenter parameters he wants to display in function of time


  • • Ruler to read values on the graphs

Data archive


The process data (temperature, pH,...) are stored in a text file. This file can be exported to most programs on the market for statistical treatment or reporting. More fermentation batches can then be compared for process optimization.

Process control


  • • Remote control of the fermenter, all the set point values can only be changed from the PC


  • • Possibility to know the amount of base and acid added into the fermenter


  • • Profiles on all the set points like temperature, pH, pO2, air flow rate, agitation, parameter X or feed with a peristaltic pump (figure 3)


  • • Alarm management: The user can activate alarms for temperature, pH, pO2, air flow rate, agitation, parameter X.


  • • The program shows when an alarm has occurred.
