The magnetic levitating mixers  STE.M.® comply with all requirements of GMP, U.S. Pharmacopoeia and all Italian and CE Directives, infact:

1. Eliminate all  risks of infection and contamination of personnel and products.

2. Are completely open on top and are easily cleaned and sterilized in placeWithout dismantling

3. Are permanently levitating while stopped and all over operation at all speedsof agitation.
   These characteristics, patented since the year 1996, provide the exclusive
   

Advantages:

Superior hydraulic efficiency realized eliminating all sources of wear and adopting the most suitable profiles of impellers for each  process demand.

Zero dead legs as all parts are fully and continuously flushed, including the rearof impellers and bearings

Magnetic levitation which avoids the mechanical contacts on the thrust blocks,eliminates the mechanical wear, the local heating and protects complex
molecules and biotechnological products.

Foam free agitation adapted to productions of  vaccines, blood derivatives, proteins extractions andother processes with surface-active components.

Easy procedures of validation with all certifications of materials and Conformity declarationsenclosed with the Users’ Guide.

Interchangeable as every impeller of any size can be replaced with impellers of the same size with different profiles for other productions; for example the traditional axial impellers can be replaced with centrifugal impellers or homogenizers of the same size, without changing the support welded in the bottom of the tank.
