Product enters the system via the inlet reservoir and is pulled into a constant pressure pumping system which pushes the material through a fixed geometry interaction chamber at up to 30,000psi (2068 bar) where it experiences consistent, high shear rates and impact forces. All material receives the same treatment to achieve consistent, reliable results.
After passing through the interaction chamber, the product is effectively temperature controlled and collected. The combination of the constant pressure pumping system and exclusive fixed-geometry interaction chamber are what makes our Microfluidizer^® technology superior and enables our customers to achieve unparalleled success.

Highest Shear Rates

As shown in the shear rate and particle size distribution charts below from Chemical Engineering, Microfluidizer^® processors consistently generate significantly higher shear rates than other methods and more uniform particle size reduction.

By precisely controlling the level of shear applied, customers are able to process shear-sensitive materials and high-pressure applications. More efficient reduction of particles to the nano level allows customers to use less energy to achieve particle size results that are, on average, half the size of even the most effective homogenizer outputs.

Uniform Particle Size Distribution

Creating tiny particles is one step. A crucial second factor, often overlooked by manufacturers of other particle size reduction equipment, is generating a uniform particle size distribution in the process.

This is where Microfluidizer^® technology has proven its value in thousands of customer applications over the years: producing the most narrow particle size distribution results possible. Naturally, this yields greater stability, longer shelf life, more efficient use of raw materials, and significant potential savings in the filter area.

Smaller Particle Sizes

Microfluidizer^® processors generate unrivaled shear that is orders of magnitude higher than homogenizers. This results in significantly smaller average particle sizes. A test was conducted to compare a Microfluidizer^® processor and an Avestin homogenizer in liposome processing. Both pieces of equipment were operated at 30,000 psi. As shown in the chart below, the Microfluidizer^® processor achieved more than 50% smaller particles at every pass.

Uniform Processing Pressure

Another key advantage of the Microfluidizer^® processor is its ability to produce more uniform output vs. a homogenizer, as demonstrated in the liposome processing results.

Homogenizers operated at peak pressures for mere moments (approximately 7%) of each cycle (see chart below), which leads to wider deviations, less stable products, and the need to run more passes or use higher pressures than should be required — potentially denaturing proteins during cell rupture and adding time, energy and cost to the production process. Conversely, Microfluidics technology generates consistent shear in order to produce reliable and repeatable results.
