LUMiSizer® - The All-in-One Dispersion Analyser

The new generation of the High-End Dispersion Analyser LUMiSizer®, is your complete dispersion lab, all in one instrument. The quick characterization of any separation phenomena, like sedimentation, flotation or consolidation and the calculation of the velocity distribution in the centrifugal field as well as of the particle size distribution makes the LUMiSizer® the instrument of choice for research, development and QA/QC.
The multisample analytical photocentrifuge is ideally suited for characterization and optimization of dispersion stability and shelf-life as well as particle-particle interactions, compressibility of particles and flakes, the structural stability and elastic behaviour of sediment and gels.

Separation phenomena are quantified regarding clarification velocity and instability index, sedimentation and flotation velocity of particles, residual turbidity, separated phase volume (liquid or solid), sediment consolidation or dewaterability. With the LUMiSizer, stability tests are up to 5000x faster than performed in a test tube under earth gravity by naked eye. Fast stability ranking and shelf-life determinations of dispersions in original concentration are
done in minutes/hours instead of months/years. The obtained results correlate well with the sample behaviour at normal gravity.

The consolidation behavior of sediment and particle networks can easily be determined. Particle size distribution and velocity distribution are calculated on the basis of the two analysis modi “constant Position”- Concentration detection over time at one position and the unique “constant Time”- Concentration detection over the entire sample length at least for one time. Comprehensive information is provided with respect to the multimodality or polydispersity of dispersed particles. The software animation tool displays the recorded measurement data with programmable playback parameters for easy recognition & identification of complex separation phenomena.
The modular and object oriented design of the software provides easy extension and customizing opportunities on customer‘s request, i.e. for special R&D or QC tasks.

Giving hydrodynamic particle density, separation velocity distribution and particle size distribution in addition to the direct stability result, the All-in-One-Dispersion Analyser LUMiSizer® is one instrument for the comprehensive understanding of complex industrial products in an easy way.
