    Bacterial Fermenter/Bioreactor 1.5 / 3 / 6 Liter

All this – and more.

The Minifors 2 comes as a complete package with everything you will need for the culture of microorganisms. The fully equipped culture vessel is located on a compact base unit with four freely configurable pumps, pH and pO2 sensors, two fully automatic gas lines with mass flow controllers and a touch screen control unit. In addition, the Minifors 2 offers optional features with which you can understand and optimise your bioprocesses even more easily.



Culture vessels
  • Available in total volumes of 1.5 L, 3 L and 6 L
  • Quick and easy change between culture vessel sizes
  • Rounded flat vessel bottom: Low minimum working volume, good mixing, stability with or without a vessel holder
  • Safe sampling without any dead volume: INFORS HT Super Safe Sampler
Top plate
  • Intelligent design for easy access to all ports
  • Sufficient ports, for standard fittings and extra inlets, immersion tubes and sensors
  • 4 x 7.5 mm: addition ports available for acid, base, feed & 1 free
  • 4 x 10 mm: sparger, anti-foam system, temperature sensor, sampling/harvest
  • Maximum 7 x 12 mm (Pg13.5): pH, pO2, exhaust gas cooler, inoculation are pre-allocated, 3 are freely available
  • Convenient, tool-free cleaning and maintenance thanks to knurled screws
High-performance pumps
  • 4 High-performance pumps
  • Configurable operating mode: digital (fixed-speed) or analogue (variable speed)
  • 3 x fix (acid, base, antifoam), 1 x variable (feed)
  • Autoclavable pump heads
  • Gravimetric feeding with dosing mode (requires external scale)
  • Profile-based pump-speed control (with eve®)
  • 2 analogue inputs / outputs to connect external pumps (version for cell cultures)
  • 2 integrated MFC for air, air/O2, or air/N2 (version for microorganisms)
  • 5 integrated MFC for air, O2, N2, CO2 and head space gassing (version for cell cultures)
  • Integrated pressure sensor for detecting a blocked filter
  • Gassing optimised for bacteria applications and cell cultures: specific gassing rate (vvm) up to 2.0 min-1
  • Multiple cascades for pO2 control by means of stirrer speed, gassing rate (“TotalFlow”) and/or gas composition (“GasMix”)
  • Robust, digital connection of pH and pO2 sensors
  • Optical pO2 sensor: immediately ready for use, no polarization required
  • Calibration data stored in sensor head
  • Product calibration of the pH sensor for reliable measurements during long-running bioprocesses
  • Optional: biomass sensors from Optek and aquila biolabs
Operating unit
  • Integrated 7" touch screen (17.8 cm)
  • Simple handling through intuitive menus and practical on-screen help
  • Calibration of pH, pO2 and OD sensors using simple install wizards
  • Direct data export to USB drive in stand-alone operation
  • Multiple display languages
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
