Stirred-tank bioreactor Vario series

laboratorycell cultivationwith agitator

The exclusive stirring bioreactors are used for cell cultivation of shear stress insensitive cells as bacteria and many plant cells. They work completely automatically and are equipped with stirrer, magnet clutch, probes and fittings. They can be converted easy with few basic components into fixed bed systems. The stirring mini-bioreactor "Vario" is offered with double coat vessels for the cultivation of cells with a stable cell wall. The mini bioreactors are offered with 0.5 or 1 litres volume as standard instruments. The capacities of inner vessels are 100- 125 ml “Vario 500” and 125-250 ml “Vario 1000”. They can be offered also as multi system with 4 bioreactors. The outstanding features of the mini-bioreactors are separable double vessels with high lid occupancy density, the saving of expensive nursing media with the same cell yield results by the conical forms, the low height and the small diameters of the inner vessels.
