Aber Futura – Inline sensor for viable biomass measurement in bioreactors
The principle of the Futura system is based on cell capacitance technology (the ability of a cell to collect an electric charge). Cells with intact plasma membranes in a fermenter can be considered to act as tiny capacitors under the influence of an electric field. The non-conducting nature of the plasma membrane allows a build-up of charge. The resulting capacitance can be measured: it is dependent upon the cell type and directly proportional to the membrane-bound volume of these viable cells.
ABER´s technology converts capacitance into a live biomass reading, typically cells/mL or g/L. However, other units can be derived from the raw capacitance measurements; these may be more relevant to the chosen application. FUTURA also measures the conductivity of the medium. Conductivity is not used to measure biomass but is indicative of the production or utilization of ions by the cell suspension.
The robustness and proven performance of Aber’s sensors make them the first choice for manufacturing, providing a clear and consistent scalable pathway from R&D and process development all the way through to cGMP manufacturing.
The FUTURA system is a modular system existing of 3 hardware components and a software package. Need help in building your own FUTURA system? Please contact us and we will get in touch with you to discuss the most suitable option for your needs.
Aber Futura System Components
The FUTURA system contains three primary hardware components: the probe, the head amplifier, and the transmitter (connection hub). Various probes are available to suit all applications and bioreactors of different sizes. The head amplifier is the system’s main processing engine, powering the probe and transferring critical data to the chosen output. It is available in two distinct variants for reusable bioreactor systems. Transmitters or connection hubs come in a variety of options, depending on your output needs. It interfaces the system to a PC or any bioreactor control system. For validation and testing of the system, there is a probe tester and signal simulator available.
