Sartorius, FMB114867, Flexel® Bags for Magnetic Mixer without Sensors - Silicone and TPE - No Drain Valve - 50 L

Because media powders tend to float, a strong vortex is required for their downward entrainment to the impeller and their subsequent dissolution.
The strong vertical vortex of Flexel®for Magnetic Mixer combined with the baffle effect of the cubical design allows for instant downward movement and efficient dissolution of floating powders. The high torque provides a fast dissolution of media powders and an efficient mixing of high concentration buffers or viscous products.
For downstream intermediate purification and drug substance/product formulation, we recommend using the Low Shear Flexel®for LevMixer®.
