3. Magnetic impeller


Stirrer design can influence mixing time and efficiency, nutrient and oxygen distribution, mass and heat transfer. Due to the fact that mammalian cells have no cell wall they are fragile and express higher sensitivity to hydrodynamic shear forces than prokaryotic cells. For mammalian cell cultivation, “Marine Propeller” is the best-suited impeller because it offers the best performance in term of cell growth and biomolecule production at acceptable pressure.
