DAC - Dual Asymmetric Centrifuge

Hauschild SpeedMixer® DAC Technology

The original DAC - Dual Asymmetric Centrifuge. A Hauschild Mixing Principle from 1973.

This is the DAC - Dual Asymmetric Centrifuge.

'The' original DAC principle was first discovered by Gerd-Ulrich Schmidt and used in the worlds first Hauschild SpeedMixer® instrument, which he invented and built in Germany, 1973.

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

His DAC mixing principle using a closed mixing bowl with no mixer blade as demonstrated above. This contra-rotates on two separate axis, hence the term Dual Asymmetric Centrifuge.

The combination of these two centrifugal forces acting at different levels provides very fast, high sheer mixing, with simultaneous removal of air inclusion from a very quiet and stable, variable speed, precision controlled instrument designed for fully repeatable processing.

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

The Hauschild SpeedMixer® is a precision laboratory instrument for eficient, rapid, controlled mixing, dispersal or pulverization of dis-similar substances and / or chemicals in very short time with fully reproducible results.

The DAC mixing principle is a highly efficient,  very low energy consumption, high speed  rotation force that generates a material flow to ensure homogeneous and simultaneous air / bubble-free mixing of different substances.

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 1973.


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 RPM between 300 to 3500. This generates an incredible and unrivaled power producing more than 1000 times the force of gravity (g-force) .
