DAC - Dual Asymmetric Centrifuge
Original Hauschild SpeedMixer® DAC Technology
Air Free Material Mixing - A 50 Year Old Standard
1973 - Dual Asymmetric Centrifuge (DAC) Invented
1974 - First DAC Hauschild SpeedMixer® Made By Hand
Hauschild DAC Dual Asymmetric Centrifuge
- The Real One -
'The' original DAC principle was first discovered by Gerd-Ulrich Schmidt in 1973. 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 our No1 world leading, formulation
and production material mixers today in 2024.
His high sheer mixing principle used a closed mix cup with 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, Efficient, Bubble-Free, Quiet, Non-Invasive German Quality.
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 so it is immediately ready for the next batch – with no cleaning required.
The DAC mixing principle is the most ecconomical process, using very low energy consumption, for high speed, high sheer generated from dual rotational g-Force generating movement in materials ensuring homogeneous and simultaneous air / bubble-free mixing when processing similar or different substance types.
Hauschild DAC - Variable Speed Control As Standard
DAC with Variable Speed Control were both combined into the original concept prototype by the Hauschild founder, Gerd-Ulrich Schmidt. These two ground breaking funtions have been incorporated into every original SpeedMixer manufactured under his lead between 1974 and 2024.
This first original Hauschild SpeedMixer® incorporated a variable speed control so the operator could manually alter and fluctuate the RPM mixing speed whilst mixing without pausing or stopping to establish the best 'recepie' needed for an optimum mix.
The 'Oldie But Goldie' DAC150 Laboratory SpeedMixer® operates between 300 to 3500RPM. This generates an incredible, unrivaled power exceeding 1000 times the force of gravity (g-Force).
