While the slurry is being mixed it is mixable and pourable. If agitation is stopped the slurry becomes firm requiring the input of much energy to resume mixing. Slurry complexations can be carried out in a tank equipped with an agitator or in the case of more concentrated slurries a roller mill or ball mill
Incubator Hoods can be combined with the shakers for temperatures up to 60C can also be used as independent units . Infrared heaters for fast heating of samples without open flame . Homogeniers with knives for mechanical crushing of samples at very high speed . Vibrogen Cell Mills for the dissolution of samples according to the ball mill principle
The robust highperformance drive makes the mill suitable for longterm grinding processes up to 99 hours. Hence the MM 500 is the first mixer mill in the market to provide a real alternative to grinding in a planetary ball mill with more comfortable handling and less warming effects
