DAC - Dual Asymmetric Centrifuge

Original Hauschild SpeedMixer® DAC Technology

 1973 - Dual Asymmetric Centrifuge (DAC) The Original
1974 - Very first DAC Hauschild SpeedMixer® invented

The Hauschild DAC - Dual Asymmetric Centrifuge.

'The' original DAC principle was first discovered by Gerd-Ulrich Schmidt in 1973. Later incorporated into the worlds very first Hauschild SpeedMixer® instrument, which he invented and built by hand in Hamm Germany, 1974.

This same non-invasive DAC technology is 
still used in all the No1 world leading, formulation
and production material mixers today.

His high sheer mixing principle used a closed mix cup no mixer blade as demonstrated above. This contra-rotates on two separate axis, hence the term Dual Asymmetric Centrifuge (DAC).

The combination two opposing centrifugal forces acting at different levels provides very fast, efficient high sheer mixing, with simultaneous removal of any air inclusion. This gives us the very quiet and stable, variable speed, precision controlled instrument designed for fully repeatable processing which we know today as as the DAC + SMART-DAC Hauschild SpeedMixer®.

Fast, effective, bubble-free, quiet, non-invasive.

Any Hauschild SpeedMixer® is a precision laboratory instrument built for repeatable, efficient, rapid, controlled mixing, dispersal or pulverization of dis-similar substances and / or chemicals. This occurs in a very short time with fully reproducible results with no waste, so no clean up.

The DAC mixing principle is the most ecconomical process, using very low energy consumption, for high speed rotational g-force that generates movement in materials to ensure homogeneous and simultaneous air / bubble-free mixing of different substance types.

The Original DAC Hauschild SpeedMixer® invented by Gerd-Ulrich Schmidt in 1973.

Variable Speed Control.

DAC with Variable Speed Control were both combined by the Hauschild founder, Gerd-Ulrich Schmidt, into the worlds first ever SpeedMixer invented by him in 1974.


This first original Hauschild SpeedMixer® incorporated a variable speed control allowing the operator to manually alter and fluctuate the RPM mixing speed during the actual mixing process without stopping the machine. 

The 'Oldie But Goldie' DAC150 Laboratory SpeedMixer® operates between 300 to 3500RPM. This generates an incredible, unrivaled power producing more than 1000 times the force of gravity (g-force).
