Standard Remote Futura

Head amplifier for biomass measurement

The Standard Futura is an essential component of the FUTURA system, designed to enhance bioreactor processes. This head amplifier serves as the system’s primary processing engine, driving the probe and facilitating the transfer of vital data to the desired output. Specifically designed for smaller vessels with limited head space, the Standard Remote Futura is perfectly suited for small bioreactors with working volumes as low as 100ml. Its slim and lightweight pre-amplifier allows for easy integration, even in compact setups. To maximize flexibility, the main Futura housing can be conveniently mounted at a distance from the bioreactor vessel, up to a maximum of 1 meter.

The FUTURA system itself focuses on measuring the Capacitance, an electrical property of cell suspensions, which has been linked to live biomass in academic and industrial research. By converting capacitance into live biomass readings such as Cells/ml or g/l for Spun Solids dry weight, the Standard Futura enables the quantification of biomass. Moreover, it also measures Conductivity, expressed in millisiemens per centimeter (mS/cm), which provides insights into the production or utilization of ions by the cell suspension.

In addition to the three primary hardware components, which include the sensor probe, the Futura instrument, and the communications hub, the FUTURA system is complemented by the FUTURA SCADA software, which provides advanced functions for data analysis and mining.
