High pressure homogenizer's are widely used in the pharmaceutical, cosmetics, nutraceuticals and chemical industries to make emulsions, suspensions and dispersions.

For quick contact please click the 'Ask a Question' or 'Leave a message' tab.

The quality parameters of emulsions, suspensions and dispersions are:

Smallest droplet size – smallest ratio of droplet surface area to droplet volume

Narrow particle size distribution – most of the droplets at or below the target size and no "tails" on the distribution graph

The benefits include higher stability (longer shelf life), sterilisation by filtration (for medical suspensions), higher efficacy (absorption), controlled release, odour and flavour masking and, often, lower production cost.

Our homogenizer's excel at efficiently producing emulsions, suspensions and dispersions with droplets and particles in the size range from a few nanometers to a few micrometers and very narrow particle size distributions. This is accomplished by three different physical mechanisms:

Impingement on entry to the nozzle area

High liquid shear in the nozzle

Sudden pressure drop upon discharge

The following unique features enable the user to create emulsions and dispersions with smallest particles sizes and narrowest particle size distributions in the smallest number of passes:

Ultra high pressure, to maximise the intensity of the process

Exceptionally wide range of pressure, for maximum versatility

Precise control of the pressure throughout the range, and constant pressure once set, for narrowest particle size distribution, reproducibility and scalability

Sophisticated temperature control systems, including pre- and post-cooling or heating, to preserve product integrity

The table below illustrates.
