Multi-Frequency PENTAX fluid mixers are used where two mutually insoluble liquids must be continuously mixed into a stable emulsion, or where solids in suspension must be dispersed as finely as possible in a viscous liquid.

Design and construction
The multi-frequency liquid mixer comprises a series of opposed rotors and stators on a common axis. The rotors are fitted with milled teeth for low viscosity applications and with round studs for use with viscous fluids.
Inside the PENTAX mixer, constantly changing areas of rapid flow and resistance subject the liquid to high frequency acceleration and deceleration.
The resulting high energy shear forces result in effective dispersion and emulsification.
A pre-mixing chamber is located at the entrance to the mixer. When one or more components are fed in by non-synchronous piston or diaphragm pumps, this chamber accommodates the discharge volume of several pump strokes and thereby equalises any differences in concentration before the liquids enter the main mixing area
Advantages
- Extremely fine droplet size and material distribution
- Low space requirement
- High shearing action and phase boundary area
- Rapid reaction rate for neutralisation and other reactions
- Effective material exchange for reactions involving gases
