Ultra-fine dispersing machine for emulsions and suspensions

Producing the finest micro-emulsions and suspensions requires a mixing machine that generates extremely high shear.  Multi-staged rotor/stator dispersing machines work well for this purpose because of the high shear forces applied to the mixture at each rotor/stator stage.  A rotor /stator dispersing machine that also incorporates extremely fast rotation and resultant tip speeds for even greater shearing action will lead to the creation of super-fine emulsions and ensure the success of your process.

Top-of-the-line rotor/stator dispersion with utlra high shear for nano-scale particle emulsions and suspensions

The DISPAX-REACTOR® DRS from IKA is an inline ultra high shear dispersing machine used to achieve the finest micro-emulsions and suspensions. Extremely high shear rates (up to 190.000 1/s) combined with a fine generator geometry enable crushing of droplets and solids particles down to the nanoscale. The resulting product has long-term stability which reduces the need for emulsifying agents and thickeners. Because of the extremely high energy density, other dispersing aids can be reduced or possibly eliminated.

The DRS is usually equipped with a two-stage rotor-stator system (generators). The high tip speed of 40 m/s (10.000 fpm) often negates the need for a third stage. The ultra-fine dispersing machine, designed with the same high quality features as the ULTRA-TURRAX® UTL and the DISPAX-REACTOR® DR, is especially well suited for challenging pharmaceutical applications.  The units are designed for easy and reliable scalability and sizes are available with flow rates from 70 to 40.000 liters per hour.
