Application :
Fill and drain operations with sterile vessels blending Dispersion Homogenisation Suspension
Operative range :
Vaccines Insuline Suspensions APIs prone to foaming

In many cases, pharmaceutical end products need to be stirred continuously prior to entering the final filling stage. Given this requirement, the main challenges are :
  • Steady stirring until 'the last drop'
  • Minimized deadleg for complete product harvest
  • Prevention of vortex-caused incorporation of gaz bubbles
  • Prevention of foam formation caused by too vigorous stirring
Amplitude controllers AC-051 used with Rütten Vibromixers make all this possible. AC-051 is an intelligent floor mounted weighing frame. Vessel with vibromixer on a trolley are driven into the frame. During operation, its load cells register the exact weight and adapt stirring amplitude correspondingly, during fill and drain operations. Five programmable speed ramp types are available, allowing either discreet or continuous adapation of the stirring amplitude. An unlimited number of recipes can be used. By reducing the stirring amplitude during emptying, stirring is kept up longer, allowing more of the media to be used for fill and finish.
