What is laboratory dispersion and homogenization?

27 Feb 2024

In the ever-evolving landscape of laboratory technology, digital dispersers have become indispensable tools for achieving precise and efficient sample preparations across various industries such as Cosmetics, Food and Feed, Pharma and Biotech, and much more.

These versatile instruments play a significant role in achieving homogeneous dispersions and high speed mixing of various materials, ensuring effective sample processing, and, consequently, accurate analytical results.

What is dispersion?

Dispersion refers to the process of distributing or spreading a substance, such as particles or components, evenly throughout a medium. In the context of laboratory work, dispersion often involves creating a homogeneous mixture or distribution of particles within a solution or matrix, ensuring uniformity and consistency.

In practical terms, dispersion can take various forms and usually describes a laboratory application in which it is necessary to mix, suspend, emulsify, disintegrate, and dissolve two or more immiscible phases in a fluid to produce a mixture.

How does homogenization work?

In the context of laboratory dispersers, like the OV 625 Digital Disperser, homogenization is facilitated through the mechanical action of a high-speed rotating blade (the rotor) within a stationary stator.

The instrument creates a shearing effect, breaking down aggregates and dispersing particles evenly in the sample solution. The speed and efficiency of this process contribute to the homogeneity of the final mixture and the achievement of the desired particle fineness.

Which dispersing tools can be used?

Various dispersing tools can be used to achieve effective sample dispersion based on a specific laboratory application.

The choice of dispersing tool depends on factors such as the sample type, size, and the degree of dispersion particle fineness required: selecting the proper dispersing tool is crucial to achieving the best performance and high reproducibility.

Different types of dispersing tools are required to process different fluids. Sometimes it is necessary to use two dispersing tools to achieve specific requirements. Together with the convenient quick disconnect and installation system, it is possible to effortlessly change the dispersing tool so you can move onto the next step of the homogenization process.
