Dispersion is a mixture of a solid within a fluid where the solid exists as particles, of microscopic or ultramicroscopic size, distributed throughout the liquid.  Typically solids do not remain stable within a fluid and separation occurs quickly; solids will remain in suspension by their own free will if they are small enough for gravity to be compensated for by the kinetic energy present within the mixture.  Mechanical means such as agitation, fluid acceleration, cavitation, vibration, shaking or excessive direction change will help reduce particle sizes of the solids so that it remain in suspension.  Sonic's purpose is to develop equipment that will form dispersions for you with sub-micron particle sizes and uniform particle size distributions that don't separate readily and possess enhanced shelf life and stability.  Even finely dispersed solids over time will agglomerate, coagulate or flocculate into larger particles, or coagula or flocs.  Our equipment is also used to eliminate these larger formations.

Our Sonolator Homogenizing Systems have been used in all the major industries to form superior emulsions on a continuous basis.  We use the power of fluid acceleration, cavitation and high pressure to dramatically reduce phase droplet sizes and create extremely stable emulsions.  The Sonolator, seen here, houses a specially engineered Orifice that subjects material to high pressure and cavitation.  A PD pump, instrumentation, controls and PLC are used to make a complete homogenizing system.  Because the Sonolator works in-line on a continuous basis, it lends itself well to Multiple-Feed Homogenization.  This is where a Sonolator system containing 2 or more PD pumps and a Sonolator meters various phases, phase 1 being water and phase 2 being silicone oil for example, and emulsifies them instantly at point of contact at the Sonolator Orifice.  This allows for oils to be drawn from bulk, water to be drawn from source without being placed in a process tank and saves on overall time and expense!

Our Colloid Mills have been used in all the major industries to form superior emulsions on a continuous basis.  We use the power of mechanical shear to dramatically reduce phase droplet sizes and create very stable emulsions.  The RotoMill, seen here, houses a specially engineered Rotor that turns at high speed within a stationary Stator; process fluids are subjected to intense hydraulic shear as they pass through the gap.  Colloid Mills have been an industry standard for many applications such as mayonnaise emulsions.  Our Colloid Mill is leading the industry in design innovations and is definitely the best in its class.  With improved bearing and seal life via a specially designed removable chamber, the stability and reliability of this mill are unmatched!
