Description
Powerful, robust, small-scale magnetic mixers, which are able to operate at high agitation rates (up to 1500 RPM). Ideal for laboratory tanks (up to 10 L working volumes). Thanks to the high torque rating, the D20 series mixers are able to provide optimal mass transfer rates even in highly viscous liquids. In the proposed design, a gap between the outer rotors and the hermetic containment housing is maintained in order to avoid grinding between rotating and static elements. Simultaneously, two concentric lines of suction slots were machined into the body of the outer rotor. The upper layer slots guide the liquid in such a way, so that the movement on the boundary layer during rotation would be directed towards the gap between the containment housing and outer rotor. In the vicinity of the lower suction slot layer the flow direction is opposite that of the upper layer, so that liquid would move from the air gap to the outside environment. Such design aspects, considering the suction slots, were envisioned, in order to avoid flow stagnation in the air gap between the outer rotor and the containment housing, which is crucial during both microorganism cultivation/fermentation processes and CIP procedures.
