LAMBDA MINIFOR fermentor-bioreactor, designed for bench-top surfaces in laboratories is suitable for volumes from as low as 35 ml to 6.5 l.
LAMBDA MINIFOR fermentor - bioreactor has been designed such that several of these can be placed side by side and are well suited for the optimization of bio-transformations and growth parameters of the culture. LAMBDA MINIFOR takes up the minimum amount of space on the laboratory benches and allows having good access to all parts of the unit.
MINIFOR can be used either to work independently or it can be connected directly with a PC to control it remotely and for extensive data treatment, regulation and storage.
Several innovations and new ideas have been introduced.
• For many years, the whole glass vessels have been used in cell cultures and proven to maintain perfect sterility, we have used this idea in our fermentor / bioreactor.
• The agitation system is based on up-and-down movement. The agitator system has a motor with a membrane ensuring sterility and efficient mixing without forming a vortex (thus no baffles are needed). The bio-mimicking 'fish-tail' stirring discs offer maximum efficiency without cutting edges; they mix the cells gently and produce less foam.
• The culture is heated by 'sun-like' radiation with a gold reflector and a parabolic radiator under the vessel to maintain the temperature precisely
• Compact unit, without a casing tower, it is possible to measure and control six parameters with the use of its modern microprocessor stored at the front of the instrument.
LAMBDA MINIFOR fermentor-bioreactor system includes the Advanced and Start-up kit.
