Alfa Laval
This company is expanding its range of magnetic mixers with the new LeviMag UltraPure (photo), which is engineered for the sterile production of biotechnological and pharmaceutical products. These mixers are based on the same patented, hygienic design as their predecessors, and feature an impeller that levitates on a powerful magnetic field at all times, so there is no direct contact between the axial part of the bearing surfaces. They are designed to meet the demands of liquid-based pharmaceutical formulations that require the validation of mixer cleanability, drainability, bioburden control, low-shear performance and thorough documentation. Capable of operating at a broad range of speeds, the magnetic mixer features a specially designed four-wing impeller that delivers high pumping efficiency. This safeguards product integrity, provides full drainability and ensures efficient mixing, since the mixer can be run dry. — Alfa Laval AB, Lund, Sweden
