All this – and more
The Minifors 2 comes as a complete package with everything you will need for the culture of microorganisms and cell cultures. The fully equipped culture vessel is located on a compact base unit with four freely configurable pumps, pH and pO2 sensors, up to five 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.

Unpack and get started
The Minifors 2 will take you directly to your bioprocess. The bioreactor is preconfigured and delivered ready to use. Connect the device, mount the vessel, connect pumps and sensors and begin to work after only 10 minutes.

Design for practical applications
The Minifors 2 has a compact, user-friendly design. With its small footprint and few external connections, the bench-top bioreactor takes up little space in the lab. Your work around the bioprocess will be simplified by special details; for example, the practical vessel holder that enables the safe and risk-free transport of the pump heads and the bottles together with the culture vessel. Also, the steel drip tray can be easily cleaned, even if the bioreactor is in operation.

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
