L.U.M. GmbH, market leader in innovative instruments to analyse stability, shelf life, particle size distribution of semi-diluted or concentrated dispersions, presents a new technological platform for comprehensive dispersion analysis, realized in the product lines LUMiSizer®, LUMiFuge® and LUMiReader®.

The cutting-edge patented STEP®-Technology meets the increasing demand for fast stability analysis and shelf-life determination of high concentrated dispersions and particle sizing in industrial and public research and development and industrial QA/QC. The technology is based on the Space and Time resolved measurement of Extinction Profiles of dispersions in a sample cell, during the demixing processes in a gravitational or centrifugal field.

The Dispersion Analyser LUMiSizer® is your complete dispersion lab, all in one instrument. The quick characterization of any demixing phenomena, consolidation and determination of particle size distributions make the LUMiSizer® the instrument of choice for research, development and QA/QC.

The instrument determines demixing processes of dilute or concentrated suspensions/emulsions for up to 12 different samples simultaneously. Even different sample cell types and physical references can be measured at the same time.

The multisample analytical centrifuges LUMiSizer® and LUMiFuge® can accelerate the demixing process up to 5000x compared to traditional test tube tests. Fast stability analysis and shelf-life determinations of high concentrated dispersions are done in minutes/hours instead of months/years. The LUMiSizer® is ideally suited for characterization and optimization of dispersion properties by measuring collective particle interactions, the compressional and elastic behaviour of sediments. The concentration, viscosity, complexity and particle size of a wide range of dispersions are easily analyzed.

The Separation Analyser LUMiReader®, determines the demixing of suspensions and emulsions for a large range of particle sizes under original storage conditions, e.g. sedimentation, creaming, flocculation and coalescence. Using a patented measuring principle, the demixing can be increased potentially by the factor of 5 and more, without applying additional mechanical forces onto the sample.

The variety of sample cells and light sources as well as temperature control up to 60 °C for all instruments meet the requirements of many applications in chemical, pharmaceutical, food and cosmetic industries.
