High-Shear Homogenizers & Dispersers - Swiss Precision Since 1962
Discover world-leading homogenizer and disperser technology engineered in Switzerland. For over 60 years, Kinematica has developed high-performance rotor-stator systems for laboratory, pilot plant, and industrial production. Trusted by R&D directors and production managers globally, our POLYTRON®, MEGATRON®, and MICROTON® series deliver unmatched reproducibility for pharmaceutical, cosmetic, food, and chemical applications.
What is a Homogenizer and How Does Rotor-Stator Technology Work?
A high-shear homogenizer is designed to break down particles in a liquid to create a uniform, stable mixture (emulsion, suspension, or dispersion). Kinematica achieves this through our proven rotor-stator principle:
- Suction Zone: The medium is drawn into the precision gap between the high-speed rotating rotor and the stationary stator.
- Shear Zone: Intense mechanical shear forces (up to 100,000 s⁻¹) and cavitation instantly reduce particles to micrometer or nanometer sizes.
- Discharge Zone: The homogenized product is expelled radially, ensuring thorough mixing without dead zones.
Homogenizer vs. Disperser:
Is There a Difference?
The terms are frequently used synonymously, but there are subtle nuances: A homogenizer aims to make a mixture completely uniform (particle size and distribution), while a disperser is specifically optimized for distributing solids in liquids (e.g., powder in paints). Kinematica POLYTRON® devices combine both functions in one system – by changing the dispersing tool (generator), both applications can be realized with the same drive.
Our Homogenizer Series: Scalable from Lab to Production
Whether you are developing a new formula in the lab or scaling to industrial throughput, Kinematica offers seamless scalability with identical process parameters. All devices are characterized by Swiss quality, digital precision, and modular expandability.
The Benchtop Class for Laboratory and Pilot Plant
The industry standard for R&D and QC. From the portable PT 1200 E (up to 400 ml) to the high-end PT 3100 D (up to 10,000 ml, 30,000 RPM, PC-controlled).
Inline Homogenizers for Industrial Production
The Megatron® Series was developed for continuous inline operation in industrial production. These devices are integrated directly into piping systems and process throughputs from 100 liters to over 10,000 liters per hour.

Why Rotor-Stator Technology? Advantages Over Other Methods
Compared to high-pressure homogenizers, ultrasonic systems, or ball mills, Kinematica’s rotor-stator technology offers decisive advantages:
- Precise particle size control: Through adjustable speed (500-30,000 RPM) and choice of generator, the target particle size can be precisely controlled – from a few micrometers to below 100 nanometers.
- Reproducible results:The digital PC software of our D-Series records every process parameter (speed, time, temperature, energy input) and enables exact repetition of every experiment – a basic requirement for GMP-compliant work.
- Seamless scalability: From laboratory (PT 1200 E, 100 ml) to production (Megatron MT, 10,000 L/h), the process parameters remain identical. This reduces development time from months to weeks.
- Low energy consumption: Compared to high-pressure homogenizers, Kinematica devices consume up to 40% less energy with comparable results.
- Easy cleaning: Tool-free disassembly of dispersing tools and CIP-capable (Cleaning-in-Place) designs minimize downtime.

How to Choose the Right Homogenizer?
4 Decision Factors
1. Sample Volume & Throughput
2. Sample Viscosity
Low-viscosity samples (water, solvents) require standard generators. High-viscosity samples (creams, pastes, doughs) require special generators with large openings and high shear force. Our Accessories Page shows all available tool options.
3. Target Particle Size
For micrometer ranges (5-50 μm), standard homogenizers are sufficient. For nanoparticles (<500 nm), we recommend high-speed models like the PT 3100 D with 30,000 RPM or ultrasonic systems like the BSP-1200.
4. Regulatory Requirements
For GMP-required applications (pharmaceuticals, cosmetics), choose devices with PC software and digital documentation (all D-models). For food production, look for EHEDG-certified inline systems.
