Bioreactors
The Minifors 2 is a compact and easy-to-use bioreactor with a full range of application possibilities. It is a complete package that enables both, beginners and experienced users to easily perform applications.
Culture vessel :
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)
Gassing :
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”)
Sensors :
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
