Apex Disperser ZERO
Dispersion｜Emulsification｜Mixing｜Kneading｜Media-Free High-Shear Processing

Apex Disperser ZERO is a versatile, media-free disperser that utilizes high shear force generated by high-speed rotation to perform a wide range of processes, including emulsification, mixing, kneading, dispersion, and fibrillation. The name “ZERO” represents a zero-media high-shear processor, making it ideal for contamination-sensitive applications or processes requiring precise control.

The system consists of a rotor and stator that form an extremely narrow shear gap between them. As the rotor rotates at high speed, materials are subjected to strong and uniform shear forces within a very short time (less than 1 second). Because all slurry passes through this shear gap, uniform dispersion or emulsification can be achieved in a single pass, making the system particularly suitable for small-batch and short-process production.

By adjusting the circumferential speed of the rotor, ZERO enables both low-damage dispersion and high-intensity shear dispersion on the same machine, offering highly flexible process control.

Applicable Processes

• Dispersion or defibrillation of soft-particle slurries and high-viscosity slurries
• Continuous emulsification processing
• Media-free mixing and dispersion without bead contamination
• Continuous mixing of high-viscosity slurries

Key Applications

• Dispersion: Thick-film electrode materials (gold, silver, platinum, vanadium), semiconductor packaging materials (SiO₂-filled resins), etc.
• Defibrillation: Carbon nanotubes (CNT), cellulose nanofibers (CNF)
• Mixing: Battery materials (cathode powders, carbon materials, binder mixtures)
• Emulsification: Cosmetics (lotions), personal care products, food products, synthetic rubber latex, etc.
