Flexel® Magnetic Mixer

Because media powders tend to float, a strong vortex is required for their downward entrainment to the impeller and subsequent dissolution.

The strong vertical vortex of Flexel® for Magnetic Mixer combined with the baffle effect of the cubical design allows instant downward movement and efficient dissolution of floating powders. The high torque provides a fast dissolution of media powders or diatomaceous earth powders used with Sartoclear® Dynamics and an efficient mixing of high concentration buffers or viscous products.

For Downstream intermediates purifcation, drug substances and drug products formulation, we recommend you to use the Low Shear Flexel® for LevMixer®.
