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?

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.

Cytiva's Whatman Mini-UniPrep Syringeless Filters provide efficient and cost-effective sample preparation for HPLC and other applications.

These syringeless filters combine four products into one solution for efficient chromatography sample preparation across a broad range of applications. They are built for fast and easy high performance liquid chromatography sample preparation and analysis.

Features and Benefits

How the Mini-UniPrep Syringeless Filters Work?

Mini-UniPrep syringeless filters can be used either manually or with a multicompressor. The multicompressor allows for processing of multiple filtration samples, further reducing sample preparation time for chromatographic analysis.

Using the Mini-UniPrep syringeless filter is easy. If you are not using a multicompressor, simply place your sample in the Mini-UniPrep device, insert the plunger, and compress. Your sample is filtered rapidly and easily. The unique design allows the liquid sample to be forced into the reservoir of the plunger. Any excess air escapes though the vent hole, until the seal is engaged. The Mini-UniPrep syringeless filter can then be used in an autosampler.
